Factor Exposure: The sensitivity of a portfolio to systematic risk factors — market beta, value, growth, momentum, interest rates, credit, etc. Factor exposure analysis reveals the true sources of a portfolio's returns and risks, beyond just the individual security names held.
Factor Investing: Tilting a portfolio toward stocks with a specific characteristic that academic research links to long-run excess return: value (low P/B), momentum (high trailing 12-month return), quality (high ROE / low debt), size (small-cap), low volatility. Factor premia are real but operate over decade-plus windows and experience 5-10-year drawdowns; most retail factor investors abandon the strategy during the drawdown and miss the recovery.
Fade Period: The middle stage of a multi-stage DCF -- typically 10-20 years -- where abnormal ROIC and growth are modeled to gradually compress from the explicit-period level toward the industry structural floor (ROIC) and long-run nominal GDP (growth). The fade period encodes the empirical observation that abnormal returns are competed away over time. A DCF that skips the fade period implicitly assumes the moat is impervious for the full explicit horizon, which is rarely defensible for category leaders.
Fade Rate: In multi-stage DCF (and reverse DCF), the assumed rate at which a company's growth premium decays from its explicit-period high-growth rate to its long-run terminal growth rate (typically pegged to nominal GDP). A single-stage DCF implicitly assumes NO fade — the explicit growth rate continues to infinity — which is economically implausible because no company can compound above the broader economy forever. Two-stage and three-stage DCFs build the fade explicitly: e.g., 8% growth for 10 years, then linear fade to 3% terminal growth over years 11-20, then 3% forever. The pace of fade is often the highest-leverage assumption in the model after terminal growth itself; aggressive (slow) fade assumptions are a common way analysts smuggle optimism into a model that looks otherwise conservative.
Failure to Deliver: A trade that did not settle on the standard timeline -- T+1 (trade date plus one business day) for US equities since May 2024. When a short seller cannot deliver the borrowed shares by settlement (because the locate was sloppy or the borrow disappeared), the trade fails. Persistent FTDs trigger Reg SHO close-out requirements under Rule 204 and can land a stock on the Reg SHO threshold list, which itself signals to the market that lendable inventory has become scarce.
Fair Dealing: The obligation to treat all clients equitably when taking investment action or disseminating research — the same opportunity, access, and timing — rather than ranking them by how much revenue they generate. Its sharpest violation is front-running: trading for your own account ahead of a client order or ahead of research the client is entitled to, capturing a price move that should have been theirs. It is a breach even when the underlying opinion is correct, because the harm is the self-serving sequencing, not the view.
Fair Value: The price at which an asset would be exchanged between knowledgeable, willing parties in an arm's-length transaction. Fair value accounting (mark-to-market) produces more timely information than historical cost but can introduce volatility and subjectivity into financial statements.
Fallen Angel: A corporate bond that was originally rated investment grade but has been downgraded to high yield (junk) status. Fallen angels often trade at distressed prices after the downgrade because many institutional investors are required to sell them. Some distressed investors specifically target fallen angels that they believe will recover.
Fama-French Three-Factor Model: The Fama-French (1992) extension of CAPM that adds two factors beyond the market: SMB (small-minus-big, capturing size effect) and HML (high-minus-low book-to-market, capturing value effect). Expected return = Rf + beta_mkt * ERP + beta_SMB * SMB_premium + beta_HML * HML_premium. Used as an alternative to the build-up method for adjusting CAPM cost of equity on small-cap and value-tilted firms; structurally a substitute for the build-up size premium rather than a complement (using both is double-counting). Subsequent Fama-French five-factor (2015) adds profitability and investment factors.
Fat Tails: The statistical phenomenon where extreme events (very large gains or losses) occur far more frequently than a normal distribution would predict. Financial markets exhibit fat tails — crashes and bubbles are too common to be explained by bell-curve models. Fat tails are why VaR underestimates true risk.
FCF Conversion: A diagnostic ratio computed as Free Cash Flow divided by Net Income. A multi-year average above 1.0 indicates the business converts every dollar of accounting profit into more than a dollar of actual cash, characteristic of mature consumer staples, asset-light services, and high-quality software. A multi-year average below 0.5 indicates that half the reported earnings never reach cash form, characteristic of capital-intensive industrials and a flag for software companies that should be running well above 1.0. The trend matters more than the absolute level — a declining conversion ratio with stable reported earnings is usually the earliest signal of earnings-quality decay, often visible one to three quarters before the income statement itself rolls over.
FCF Yield: Free Cash Flow divided by Market Capitalization -- the equity FCF yield, which reads like a bond yield on your investment: a 6% FCF yield means the business generates 6 cents of free cash for every dollar of market value. (This is the denominator the platform uses.) For a leverage-aware view, FCF divided by Enterprise Value -- the inverse of EV/FCF -- is the more conservative variant; use it when comparing firms with very different debt loads, because market-cap yield flatters a heavily indebted company. Common misuse: treating a single year's FCF as representative. FCF is volatile by design -- a single year of heavy capex or working-capital build can halve it. Use a 3-5-year trailing average for cyclical businesses, and always check whether the FCF figure includes or excludes stock-based compensation (the standard practitioner adjustment is to subtract SBC).
FCFE: Free Cash Flow to Equity \u2014 the cash available specifically for equity holders after operating costs, capex, working capital changes, and net debt repayments. Formula: Net Income + D&A \u2212 \u0394Working Capital \u2212 Capex + Net Borrowing. FCFE is discounted at the Cost of Equity (not WACC) in equity-level DCF models. The distinction from FCFF matters most for leveraged companies where interest payments and debt amortization are material.
FCFF: Free Cash Flow to the Firm \u2014 the cash a business generates for all capital providers (both debt and equity holders) after operating expenses and capital expenditures but before financing payments. Formula: EBIT \u00d7 (1 \u2212 tax rate) + D&A \u2212 \u0394Working Capital \u2212 Capex. FCFF is discounted at WACC in enterprise-level DCF models because it represents returns available to the entire capital structure.
FCRA §611: Section 611 of the federal Fair Credit Reporting Act, which gives consumers the right to dispute inaccurate items on their credit report for free. Once you file a dispute, the credit bureau must investigate — generally within 30 days — and must remove any item it cannot verify as accurate. Disputes can be filed online, by phone, or (strongest, for a paper trail) by certified mail with return receipt. You do not need to pay a credit-repair company to exercise this right.
FDIC Insurance: Federal Deposit Insurance Corporation coverage that guarantees deposits at member US banks up to $250,000 per depositor per ownership category. FDIC insurance was created in 1933 in response to the bank runs of the early 1930s; it transformed the deposit franchise by removing the rational reason for most depositors to run on a healthy bank. Deposits above the $250,000 limit -- "uninsured" deposits -- can still be at risk if the bank fails, though regulators have occasionally invoked discretionary backstops (as in March 2023) when failures threaten broader system stability.
Fed Balance Sheet: The Federal Reserve's holdings of Treasury bonds and mortgage-backed securities, accumulated through quantitative easing programs. Expanding it injects money into the financial system and lowers yields. Shrinking it (quantitative tightening) does the opposite and tightens financial conditions.
Fed Funds Rate: The Fed's main lever for the economy. Raising it slows borrowing and cools inflation. Cutting it stimulates borrowing and boosts growth. Affects everything.
Federal Funds Rate: The interest rate banks charge each other for overnight loans, set by the Federal Reserve. The most important rate in the economy \u2014 it influences mortgages, car loans, credit cards, and corporate borrowing. Raising it slows inflation; cutting it stimulates growth.
Fee-Earning AUM: The portion of a firm's assets under management that actually generates management fees right now -- distinct from total AUM, which can include committed-but-not-yet-invested capital, assets in a fee holiday, or co-investment money that pays no fee. For alternative managers especially, fee-earning AUM (sometimes "fee-paying AUM") is the more honest driver of near-term fee revenue than headline AUM, and the gap between the two -- "dry powder" and not-yet-earning commitments -- is a pipeline of future fee growth as that capital gets deployed.
Fee-Related Earnings: The profit an alternative-asset manager earns from its steady, recurring management fees, after the costs of running the firm but BEFORE the volatile performance fees (carried interest) that depend on investment outcomes -- abbreviated FRE. Because it excludes the lumpy, unpredictable carry, FRE is the durable, annuity-like earnings stream the market rewards with a higher multiple. It is a firm-defined non-GAAP measure with no single standard, so we show it on a firm's own page but never rank it across firms -- one manager's FRE definition is not another's.
Fermi Estimation: A back-of-envelope reasoning technique that builds an answer from a chain of rough estimates (population x penetration x price, customer-count x average-spend x capture-rate, etc.). Named after physicist Enrico Fermi, who was famous for producing roughly-correct estimates of complex quantities from chains of order-of-magnitude inputs. Each individual estimate can be off by 50% without breaking the order-of-magnitude bound on the final answer. For investors, the discipline produces cheap fast cross-checks on TAM claims, revenue runway projections, and valuation-by-inspection sanity tests before committing analytical hours to the deeper work.
FFO (Funds From Operations): The REIT industry's standard measure of operating performance: net income plus depreciation minus gains on property sales. REITs depreciate real estate that often appreciates in value, so FFO strips out the accounting distortion to show true recurring earnings power.
FFO per Share: Funds From Operations per share -- the REIT industry's primary earnings measure, replacing net income (EPS) because GAAP net income is distorted by huge non-cash real-estate depreciation. FFO takes net income, adds back real-estate depreciation and amortization, and removes gains on property sales, giving a truer picture of recurring cash-generating power per share. The critical caveat: the NAREIT-defined FFO is the standard, but many REITs headline a "Core FFO" or "Normalized FFO" that adjusts out items THEY choose -- a different, company-specific number. Compare only NAREIT-to-NAREIT, and never assume a bare "FFO" figure is the NAREIT one.
FFO Yield Method: The cost-of-equity proxy used for REITs and other high-payout pass-through structures, computed as (current FFO per share / current market price per share) + expected long-run FFO growth. The method substitutes for CAPM in REIT valuation because the 90%-of-taxable-income payout requirement under REIT rules means earnings retention is structurally constrained — most of the required equity return must arrive as current cash yield, not as retained-earnings growth. A REIT yielding 6% on FFO and growing FFO at 3% has an implied cost of equity of 9%; this is structurally the dividend-discount-model equivalent applied to FFO rather than dividends.
Fiat Money: Currency that has value because a government declares it legal tender and because people accept it — not because it can be exchanged for gold or any physical commodity. Every major currency today is fiat money. The U.S. dollar became fully fiat in 1971 when President Nixon ended its convertibility into gold. Fiat money gives central banks control over how much money exists, which is powerful but depends entirely on public trust that the money will hold its value.
FICA: Federal Insurance Contributions Act — the payroll tax that funds Social Security (6.2% on wages up to the annual wage base, in the high-$170Ks for 2025-26 vintage; SSA indexes this each year) and Medicare (1.45% on all wages, plus an additional 0.9% above $200K single / $250K married — these Medicare thresholds are statutorily fixed and unindexed). Employer matches both Social Security + base Medicare. Self-employed pay both halves on Schedule SE.
FICO Score: The credit score most US lenders use, computed by Fair Isaac Corporation from your credit reports. Range 300–850; mortgage-grade is 740+, prime auto 700+. Five factors with published weights: payment history 35%, utilization 30%, age of credit 15%, mix 10%, new credit 10%. Different FICO models exist (FICO 8 most common; FICO 9 emerging); your credit-card website usually shows FICO Bankcard 8, which weighs revolving utilization more heavily.
Fiduciary Duty: A legal and ethical obligation to act in another person's best interest, placing that person's interests ahead of your own and your employer's. It has two limbs: the duty of loyalty (act for the client's benefit, no self-dealing) and the duty of care (recommend only what genuinely fits the client after reasonable diligence). It is a stricter, best-interest standard than mere suitability — the test is "is this the best available option for this client?" not "is this allowed?"
Fiduciary Out: The contractual exception within a no-shop clause that permits the target board to ENGAGE with an unsolicited superior proposal received after signing. The fiduciary-out exists because Delaware law would otherwise hold the no-shop in tension with the board's Revlon duties; the exception preserves the no-shop's default (no active solicitation) while permitting the board to respond to unsolicited topping bids that constitute superior proposals. Triggered by a "reasonably likely to lead to a superior proposal" standard.
FIFO: First In, First Out — an inventory accounting method that assumes the oldest goods are sold first. During inflation, FIFO produces lower COGS and higher reported profits than LIFO. Most companies outside the US use FIFO because LIFO is prohibited under international accounting rules.
Fill Quality: A general term for how favorably an order executed relative to the prevailing market at the time of arrival -- typically measured against the NBBO. Best-execution rules require brokers to deliver fills at or better than the NBBO for marketable retail orders. Fill quality is the main reason serious traders care which broker they use: differences of a fraction of a cent per share, compounded over thousands of trades, become real money.
Finance Lease: A lease that in substance transfers ownership risks to the lessee — typically long-term, with a purchase option or covering most of the asset's life. Treated like a purchase on the balance sheet: the lessee records both an asset and a debt. Interest expense is front-loaded unlike operating leases.
Financial Accelerator: The feedback loop where declining asset prices reduce the value of collateral, forcing borrowers to cut spending or sell assets, which further depresses prices. This mechanism amplifies both economic booms and busts, turning manageable problems into crises.
Financial Crisis: A severe disruption in financial markets where asset values drop sharply, credit freezes, and institutions face insolvency. The 2008 Global Financial Crisis and the 2020 COVID crash are recent examples — both required massive government and central bank intervention to stabilize the system.
Financial Leverage: The use of borrowed money to amplify returns on equity. Financial leverage is a key component of the DuPont analysis. It magnifies gains when business is good and magnifies losses when it is bad. Too much financial leverage converts a temporary downturn into a potential bankruptcy.
Financial Slack: Internal cash + unused debt capacity a firm holds in reserve to fund investment without tapping equity markets. Under pecking-order theory, financial slack is itself valuable because it lets a firm execute positive-NPV projects without bearing the information-asymmetry premium of an equity issuance. A reason that profitable firms accumulate cash piles even when they have no immediate use for the cash — the slack is option value on future opportunities.
Financial Statement Analysis: The systematic process of evaluating a company's income statement, balance sheet, and cash flow statement to assess performance, financial health, and valuation. It is the foundation of all fundamental investment research.
Financing Activities: The section of the cash flow statement showing cash flows from borrowing, repaying debt, issuing or repurchasing stock, and paying dividends. A company consistently funding operations through financing activities may be burning cash faster than it generates it.
First Lien: Debt secured by a first-priority claim on the company's assets. Gets paid first in bankruptcy. Lowest risk, lowest yield in the capital structure.
First-Look Screen: A 2-4 hour initial review of a captured idea to test whether it survives basic numeric and balance-sheet sanity checks before further work is committed. The first-look screen catches names that look interesting on surface descriptions but break down on basic ratios -- e.g., debt-to-EBITDA too high to support the thesis, customer concentration unusually high, or recent disclosures that contradict the framing. Names that pass the first-look screen are promoted to a one-page preliminary memo; names that fail are filed in the kill log.
First-Order Stochastic Dominance: FOSD. One investment A first-order dominates another B if A's cumulative distribution function lies everywhere below B's -- i.e., for every loss threshold, A is less likely to fall below it. FOSD implies every investor who prefers more wealth to less will choose A over B regardless of risk attitude. The strongest possible ranking between two risky payoffs because it requires no preference assumption beyond monotonicity.
Fiscal Multiplier: The ratio of the change in GDP to the change in government spending (or tax cut) that caused it. A multiplier of 1.5 means $1 of spending produces $1.50 of GDP; a multiplier of 0.5 means $1 produces only 50 cents of GDP, with the rest offset by crowding out. The multiplier is highly state-contingent rather than a fixed constant: empirical estimates range from below 0.5 (tight monetary regime, near full capacity) to above 2.0 (zero lower bound, large output gap). State-contingency is the central feature, not a footnote.
Fiscal Policy: Government decisions about spending and taxation used to influence the overall economy. Stimulus spending during recessions and tax cuts are common expansionary fiscal tools. The counterpart to monetary policy, which is controlled by the central bank rather than elected officials.
Fisher Equation: The exact relationship between nominal rates, real rates, and expected inflation: (1 + nominal) = (1 + real) \u00d7 (1 + expected inflation). Rearranged: real = (1 + nominal)/(1 + expected inflation) \u2212 1. The familiar approximation real \u2248 nominal \u2212 inflation is a first-order Taylor expansion that's accurate within ~0.1 pp at low rates and breaks down materially above ~10% inflation.
Fixed Exchange Rate: An exchange rate regime in which the central bank commits to maintaining a specific rate against another currency, typically by intervening in foreign exchange markets and by aligning monetary policy with the anchor country. Hard pegs (currency boards, dollarization) surrender monetary independence entirely; softer pegs may allow narrow bands. Fixed regimes import the anchor countrys monetary policy stance, which is sometimes desirable (importing low inflation credibility) and sometimes destructive (inappropriate rate cycles for local conditions).
Fixed Rate Payer: The counterparty in an interest rate swap that pays a fixed interest rate and receives the floating rate. Usually a company seeking to convert variable-rate debt into fixed obligations, providing certainty about future interest costs. Benefits when rates rise (paying cheaper fixed while rates go up).
Fixed-Rate Mortgage: A home loan with an interest rate that stays constant for the entire loan term. Provides certainty — your monthly payment never changes. Rates are typically higher than initial adjustable-rate mortgage rates, but you are protected from rising rates over the life of the loan.
Flattener: A yield-curve trade that goes SHORT the short end and LONG the long end, DV01-weighted to cancel parallel-shift exposure. The trade profits if the curve flattens -- short-end yields rising more (or falling less) than long-end yields. Common during Fed hiking cycles when policy rates rise faster than long-end inflation expectations. The mirror of a steepener; both can be expressions of curve-shape views without taking an outright duration bet.
Float: The number of shares actually available for public trading -- shares outstanding minus closely-held shares (insiders, parent companies, long-lock-up institutional holders, ESOP trusts). Float drives liquidity and short-squeeze potential: a $5B market-cap stock with a 50M float trades very differently from one with a 500M float. Stocks with small floats and high short interest are the classic squeeze setup (see Days to Cover). Often called Free Float in non-US markets.
Floating Exchange Rate: An exchange rate regime in which the currency is set by market supply and demand without central-bank intervention. Major economies have run floating regimes since the collapse of Bretton Woods in 1973. Floating regimes give the central bank full monetary independence under the impossible trinity but transfer macro shocks into currency volatility, which then propagates to inflation, dollar-debt servicing costs, and equity returns translated back to home currency.
Floating Rate: An interest rate on a loan or bond that resets periodically based on a reference rate (typically SOFR, sometimes Fed Funds or the Prime Rate) plus a fixed spread. Each reset (commonly monthly or quarterly) recalculates the all-in rate as Reference Rate + Spread. Borrowers pay more when reference rates rise and less when they fall. Most syndicated corporate loans, adjustable-rate mortgages, and revolving credit facilities are floating-rate.
Floating Rate (SOFR): A variable interest rate that resets periodically based on a benchmark — typically SOFR (Secured Overnight Financing Rate) plus a spread. Floating-rate borrowers pay less when rates fall but face rising costs when rates increase, creating interest rate risk.
Floorlet: A single component of an interest-rate floor -- a European put option on the floating reference rate at one specific reset date. Each floorlet pays max(0, strike - reference rate) times notional times the day-count fraction. A floor is a strip of floorlets, one per reset date. Floorlets are priced using the same Black-style framework as caplets but with reversed payoff direction.
FOMC: Federal Open Market Committee — the 12-member body within the Federal Reserve that sets US interest rates. Meets eight times per year. Their rate decisions and forward guidance move every major asset market on Earth the moment they are announced.
FOMO: Fear of Missing Out — the anxiety that others are making money on an investment you don't own, driving impulsive buying at elevated prices. FOMO is most dangerous near market peaks when seemingly everyone is discussing gains. Buying based on FOMO is the opposite of disciplined value investing.
Forced Selling: Selling driven not by investment conviction but by external constraints — index fund rebalancing after a delisting, institutional mandates requiring investment-grade-only holdings after a downgrade, or spin-off shares distributed to shareholders who cannot hold them. Forced selling creates temporary mispricings that opportunistic investors can exploit, because the seller's motivation is structural rather than informational.
Foreign Direct Investment: FDI. Cross-border investment in productive assets where the investor takes a controlling interest (typically 10 percent or more of voting equity), as opposed to passive portfolio holdings. FDI flows are generally considered the most stable form of capital inflow -- a foreign company building a factory or acquiring a controlling stake in a domestic firm is harder to reverse than a portfolio bond holding. Countries with current account deficits funded primarily by FDI tend to be less vulnerable to sudden-stop dynamics than countries funded primarily by short-term portfolio inflows.
Foreign Reserve Adequacy: A countrys foreign-exchange reserves measured against various stress benchmarks -- typically the IMF reserve adequacy metric, months of import cover, or short-term external debt coverage. Reserves serve as the central banks ammunition for defending the currency, smoothing import payments during stress, and meeting external debt obligations when private capital is unavailable. The traditional 3-months-of-imports floor is now considered too low for countries with open capital accounts; modern benchmarks emphasize coverage of short-term external debt and a composite IMF metric.
Form 1099: A family of IRS forms reporting income other than wages -- for example 1099-INT (interest), 1099-DIV (dividends), and 1099-B (proceeds from selling investments). Issuers send copies to you and to the IRS.
Form 13F: Same as 13F.
Form 4: SEC filing required when insiders (officers, directors, beneficial owners of 10%+ of any class) buy or sell their company's stock. Must be filed within two business days of the trade and appears publicly on SEC EDGAR the same day. Reading Form 4 patterns is informative but rarely conclusive — most filings record routine compensation events (option exercises, scheduled 10b5-1 sales, RSU vesting) rather than active conviction. Oxford Ledge surfaces only trades crossing 1% of float as material; smaller activity is filtered as noise. Browse the source on SEC EDGAR. The data behind insider net-flow and clustering signals — observation only, never a trading recommendation.
Form 8-K: An SEC filing required within 4 business days of a "material" corporate event — earnings releases, CEO changes, auditor changes, acquisitions, and going concern opinions. Investors monitor 8-K filings because they contain market-moving disclosures before the annual or quarterly reports.
Form 8606: IRS form for tracking non-deductible IRA contributions and Roth conversions. Critical for Backdoor Roth: you file Form 8606 in the year you make the non-deductible Traditional IRA contribution, and again when you convert to Roth, to establish basis (so the IRS doesn't double-tax you on conversion). Failing to file means the IRS can't see your basis — you risk paying tax twice on the same dollars. Free $50 IRS penalty per missed filing.
Forward Contract: A private, customizable agreement between two parties to buy or sell an asset at an agreed price on a specific future date. Unlike futures, forwards are not exchange-traded or standardized, creating counterparty risk. Commonly used by companies to hedge foreign currency exposure.
Forward Guidance: When the Federal Reserve signals its future policy intentions to influence market expectations today rather than waiting to act. Statements like "rates will remain low for an extended period" shape borrowing costs and investment decisions months in advance of any actual policy change.
Forward P/E: Price-to-earnings ratio using NEXT year's projected earnings (typically the consensus analyst estimate). Lower than the trailing P/E when earnings are growing. More relevant for valuation than trailing P/E because investors buy future profits — but only as reliable as the underlying analyst estimate.
Forward Rate: The implied future interest rate derived from today's yield curve. If the one-year rate is 4 percent and the two-year rate is 4.5 percent today, the market is implying a one-year rate of approximately 5 percent starting one year from now. Forward rates embed the market's expectation of future short-term rates.
Fractional Kelly: The practitioner adjustment to full-Kelly sizing that risks a fraction (typically a quarter to a half) of the mathematically growth-optimal fraction in order to trade some long-run growth for substantially reduced drawdowns and greater behavioral durability. Half-Kelly typically captures around 85% of full-Kelly's long-run growth with about half the drawdown; quarter-Kelly captures less growth but is far more survivable through edge mis-estimation and fat-tailed return distributions. Most professional fundamental investors size positions in the quarter-Kelly to half-Kelly range. The right fraction is empirical, not theoretical.
Fractional Reserve Banking: The standard banking arrangement where a bank holds only a fraction of customer deposits as immediately-available cash or central-bank reserves and lends the rest out. The arrangement produces credit creation and, under stress, the vulnerability to bank runs because no bank holds enough cash on hand to satisfy all depositors simultaneously. Deposit insurance and central-bank lender-of-last-resort facilities are the institutional answers to that vulnerability.
Fractional Shares: The ability to buy a slice of a share rather than a whole one, so you invest a dollar amount instead of a share count -- $50 can buy about one-sixth of a $300 fund. Offered by every major low-cost broker, fractional shares are what let beginners start small and automate fixed-dollar contributions.
Framing Effect: A cognitive bias where the SAME choice leads to different decisions depending on how it is described -- as a gain versus a loss, or a survival rate versus a mortality rate. Because losses hurt more than equivalent gains feel good (loss aversion), a portfolio described as "down 10% from its peak" feels worse than the same account described as "up 5% for the year." Investors who deliberately reframe a holding as "cash I could redeploy today" tend to make cleaner sell decisions than those anchored to what they originally paid.
Fraud Triangle: The three conditions that typically enable financial fraud: pressure (motivation to commit fraud), opportunity (weak internal controls), and rationalization (self-justification). Developed by criminologist Donald Cressey, it's used by auditors and forensic accountants to identify high-risk companies.
Free Cash Flow: Cash generated after paying operating expenses and capital expenditures \u2014 the money the business actually produces. Unlike earnings, it's difficult to fake with accounting. Free cash flow is what funds dividends, buybacks, debt repayment, and reinvestment. The best measure of a business's economic engine.
Free Cash Flow Theory: Michael Jensen's 1986 theory that managers and shareholders have CONFLICTING preferences over excess cash: managers prefer to retain it (funds empire-building, prestige acquisitions, perks, avoids capital-market discipline); shareholders prefer to receive it (so they can redeploy to higher-return alternatives). Dividends and committed buyback programs act as COMMITMENT DEVICES — once a firm raises payouts, the political cost of reversing is severe, effectively forcing management to disgorge the cash flow stream. Explains why mature firms with weak investment opportunities create value by raising payouts even when M-M dividend-irrelevance says they should not — the value comes from REDUCING the agency cost of free cash flow.
Free Cash Flow Yield: Free cash flow divided by market capitalization — the percentage of your investment that the company generates in real cash annually. Also expressed as FCF per share divided by share price. A 6% FCF yield means the company generates $6 of cash for every $100 of market value. Useful for comparing stocks to bond yields.
Free Float: Same as Float -- the shares available for public trading. The term Free Float is common in MSCI, FTSE, and other ex-US index methodologies; US data providers more commonly say Float. See Float.
Free Rider: A participant who benefits from a good or service without contributing to its cost — the typical reason private markets under-supply public goods. If everyone can enjoy the lighthouse without paying, no individual lighthouse-builder can recover their costs, and so private lighthouses do not get built. Free-riding is also why open-source maintainers burn out, why neighborhood-watch programs struggle to sustain volunteer hours, and why collective-action problems are persistent across many domains.
Fresh-Start Accounting: ASC 852 framework that resets a post-Chapter-11 company's balance sheet to fair value at emergence. Goodwill is wiped; tangible assets revalued; income statement starts clean. The accounting reset is part of why analyst coverage takes time to rebuild post-emergence -- the company's financial vocabulary is new even if the underlying business is unchanged.
Front-Running: Trading for your own account ahead of a client order, or ahead of research the client is entitled to act on, so you capture a price move that should have been theirs. It is the sharpest fair-dealing violation and is wrong even when the underlying opinion is correct — the harm is the self-serving sequence, not the view. It breaches priority of transactions: client and employer trades come before the professional's own.
Frugality: The practice of spending less than you earn and maximizing the gap between income and expenses. In personal finance, frugality is not about deprivation but about prioritizing spending on what genuinely creates value or happiness and eliminating the rest. Every dollar not spent becomes a dollar available to invest, and that invested capital compounds over decades.
FTSE Nareit Index: The benchmark index for US REIT performance, maintained by the National Association of Real Estate Investment Trusts. Widely tracked by institutional investors, ETF providers, and analysts measuring REIT sector performance. Similar role as the S&P 500 for broader equities.
Fulcrum Security: The tranche of debt where value "breaks" in a restructuring \u2014 senior to it recovers in full, junior to it gets nothing. Identifying the fulcrum is the core distressed investing question.
Full-Case Workflow: The seven-stage integration sequence that converts a screening idea into a sized position with a written exit plan: (1) industry scan, (2) company-specific lens, (3) financial-statement reading, (4) valuation walk, (5) risk register, (6) position-sizing math, (7) exit plan. Each stage feeds evidence into the next; running them in parallel rather than in sequence is the most common reason theses that look compelling in pieces fall apart in practice. The workflow is the practitioner toolkit's answer to the question of how to integrate the disciplines learned across multiple LEARN paths into a single coherent practice.
Fully Diluted: The total share count if every potential share were converted to common stock — including all outstanding options, unvested RSUs, warrants, and convertible bonds. Fully Diluted Shares is the denominator of Diluted EPS. The gap between Basic Shares (current outstanding) and Fully Diluted Shares is the maximum dilution drag built into the current capital structure.
Fungibility: The property of money where each unit is interchangeable with every other unit. One dollar in a checking account is identical in value to one dollar of investment gains. Mental accounting violates fungibility by treating different dollars differently — leading to irrational financial decisions.
Future Value: The amount a current sum of money will grow to over time at a given rate of return. Formula: FV = PV \u00d7 (1 + r)^n. At 7% for 30 years, $10,000 grows to ~$76,000. Future value calculations are the foundation of retirement planning and compounding analysis.
Futures Contract: A standardized agreement to buy or sell an asset at a specific price on a future date, traded on an exchange. Unlike forwards, futures are marked to market daily and require margin deposits. Used by airlines to lock in jet fuel prices, farmers to lock in crop prices, and traders to speculate on commodity or financial asset prices.
