Haircut: The percentage discount applied to collateral in a repo or margin loan. A 2% haircut on $100 million in Treasuries means you can borrow $98 million against them. Haircuts protect lenders against a sudden drop in collateral value. Haircut widening during crises can force cascading asset sales.
Halving: The pre-programmed reduction in Bitcoin's new-supply issuance every ~4 years (every 210,000 blocks). Each halving cuts the block reward in half: from 50 BTC initially, to 25 (2012), 12.5 (2016), 6.25 (2020), 3.125 (2024). The total supply is capped at 21 million by protocol. Halvings have historically been followed by multi-year price appreciation periods, but the pattern is not guaranteed -- past performance doesn't predict future cycles.
Hamada Equation: The classic formula linking levered equity beta to unlevered (asset) beta and capital structure: equity_beta = asset_beta * (1 + (1 - tax_rate) * D/E). Used to (a) unlever a peer's observed equity beta to isolate business risk, and (b) re-lever an average asset beta at a target capital structure to produce the cost-of-equity input for a forward DCF. The Hamada form assumes risk-free debt (debt beta = 0), which is fine for investment-grade firms but understates levered beta for high-yield or distressed targets; the Modigliani-Miller variant equity_beta = asset_beta + (asset_beta - debt_beta) * (D/E) * (1 - t) is the corrected form when debt itself is risky.
Hard Inquiry: A credit-report pull triggered when you apply for new credit (mortgage, auto loan, credit card, sometimes apartment lease). Costs ~5–10 FICO points on average and stays on report for 24 months (impacts scoring for 12). Multiple mortgage / auto inquiries within a 14–45 day window are de-duplicated as one for scoring (rate-shopping window). Avoid in the 6 months before a mortgage application.
Hard to Borrow: A designation for a stock where lendable share inventory is thin and locating shares to short is difficult or expensive. Hard-to-borrow names typically carry borrow rates well above 1% annualized -- sometimes 50% or more -- and locates can be denied entirely. Recalls (the lender pulling shares back) happen more frequently. Most retail brokers display borrow rate or HTB status on the order ticket before accepting a short sale.
HARPEX: Tracks container ship charter rates. When shipping costs spike, it signals strong global trade demand (or supply bottlenecks). A leading economic indicator.
Healthcare Proxy: Legal document naming someone (the "agent" or "healthcare power of attorney") to make medical decisions on your behalf if you're incapacitated. Different from a living will, which directs specific treatment preferences. Goes into effect only when a physician determines you can't communicate. After 18, parents have NO automatic right to make medical decisions for you — without a healthcare proxy, the hospital follows state default rules, which often favor a spouse over a parent.
Heartbeat Trade: A pair of in-kind transactions used by some ETF sponsors to flush out appreciated holdings without realizing taxable gains at the fund level. Pattern: an authorized participant creates a large block of new ETF shares in kind, then within a few days redeems an equivalent block in kind using a different basket designed to push out the most-appreciated lots. The mechanic is legal under current US tax rules and is one reason some ETFs report essentially zero net realized gains year after year. Optically controversial but structurally available only to ETFs.
Hedge Fund: A pooled private partnership whose mandate is an absolute, market-agnostic return — making money whether markets rise or fall — using instruments forbidden to mutual funds (short selling, leverage, derivatives). Sold only to accredited or qualified investors, with lock-ups and periodic redemption windows, and a classic "2 and 20" fee (≈2% of assets plus ≈20% of profits). The bar is alpha net of fees; a long-biased fund that only rises with the market has delivered beta, not alpha.
Hedge Ratio: The proportion of a position offset by a hedge — how much of your exposure is covered. A 0.50 hedge ratio means half the position is hedged. In options hedging, the hedge ratio equals the option's delta. Setting the right hedge ratio involves balancing protection cost against remaining exposure.
Held-to-Maturity: HTM. An accounting classification for fixed-income securities a bank intends to hold until they mature. HTM securities are carried at amortized cost on the balance sheet rather than at current market value, so unrealized losses from rising rates do not flow through reported earnings or regulatory capital -- as long as the bank actually holds them to maturity. When a bank is forced to sell HTM securities to meet liquidity needs (as Silicon Valley Bank was in March 2023), the unrealized losses crystallize and can rapidly erode capital. HTM unrealized losses relative to tangible common equity are a key bank-safety diagnostic.
Held-to-Maturity (HTM): Debt securities that management has the positive intent and ability to hold until they mature, carried at amortized cost rather than fair value. Avoids income statement volatility from rate changes — but if forced to sell, the realized loss hits immediately.
Herd Behavior: The tendency for investors to follow what the crowd is doing rather than making independent decisions. Herding amplifies both rallies and selloffs and is one well-documented contributor to asset bubbles, alongside credit expansion, narrative innovation, and reflexive expectations. Recognizing the herd is easier than resisting it — pre-committing to a process (a written investment policy, a checklist) is the standard defense.
Herding: Synonym for herd behavior — following the investment crowd rather than independent analysis. In institutional investing, herding manifests as career risk: it is safer for fund managers to own popular stocks and underperform slightly than to own contrarian positions and underperform dramatically.
Hidden Assumption: A belief that an analyst is treating as load-bearing in a thesis without realizing it -- often a stickiness, durability, or relationship claim that the analyst absorbed from management without independent verification. The pre-mortem is the exercise that most reliably surfaces hidden assumptions, because the retrospective failure story forces the analyst to identify which assumptions broke. Examples: \"customers were stickier than industry norms because of dedicated equipment\" was a hidden assumption when the analyst had only the management quote as evidence.
Hidden Order: A resting order on an exchange that does not appear on the public order book until it executes. Hidden orders allow institutional traders to work large size without telegraphing their intent. The trade-off: hidden orders generally yield priority to displayed orders at the same price under most exchange rules, so a hidden order at $50.00 fills after every displayed order at $50.00 has been exhausted.
High Yield: Bonds rated BB+ or lower — also called junk bonds. They pay higher interest to compensate for greater default risk. High yield spreads widen sharply during recessions as investors price in more potential defaults.
High Yield (Junk Bond): Bonds rated BB+ or lower by Standard and Poor's (Ba1 or lower by Moody's) that pay higher interest rates to compensate investors for greater default risk. High yield spreads over Treasuries widen sharply during recessions and economic stress as investors demand more compensation for default risk.
High-Yield Savings Account: A savings account — typically offered by online banks — that pays a significantly higher interest rate than a traditional savings account by passing through the benefits of lower overhead. Rates float with the federal funds rate. Suitable for emergency funds and short-term savings where preservation and liquidity matter more than growth.
HIPAA Authorization: A signed release authorizing specific people (parents, spouse, healthcare proxy) to receive your health information from medical providers. After 18, federal HIPAA law forbids your doctor from sharing anything with your parents without it — they cannot even confirm you're in the building. Hospital admission desks have boilerplate forms; signing one at every new provider is the practical fix.
Historical VaR: A VaR calculation using the actual historical distribution of past returns. Realistic about what has happened before but blind to risks that haven't occurred in the lookback window. During stable periods, historical VaR underestimates risk for events that only appear in crises.
HML Factor: High-minus-Low, the value factor in Fama-French. Computed as the average return of high-book-to-market (value) stocks minus the average return of low-book-to-market (growth) stocks. A firm's HML loading measures its value-vs-growth tilt; a high HML loading means the firm earns the value premium in expectation. Like SMB, the HML premium has compressed post-2000 in some samples (especially US large-caps 2010-2020) but has historically been one of the most durable cross-sectional anomalies.
Hold Period: The duration of a private-equity investment from acquisition close to exit. Typical LBO hold periods range from 3-7 years, with a median around 5 years across institutional vintages. Shorter holds (under 3 years) usually reflect either accelerated value creation (genuine outperformance) or sponsor IRR-engineering (fast flip to optimize the timed-return metric). Longer holds (above 7 years) usually reflect underperformance (the deal cannot exit at the modeled multiple) or strategic alternatives that require patience. Hold-period IS the primary determinant of MoIC-to-IRR divergence: same MoIC over more years produces lower annualized IRR.
Holdings Overlap: The percentage of holdings shared between two or more ETFs. Important for avoiding unintended concentration when owning multiple ETFs. For example, SPY and QQQ overlap ~40% by weight.
Home Bias: The documented tendency of investors to over-weight their home country's stocks far beyond its share of global market capitalization. US investors typically hold 75-90% domestic equities even though US stocks represent roughly 60% of global market cap. Home bias increases concentration risk and reduces the diversification benefit of the global equity market. Source: French & Poterba, 1991.
Home Deliveries: The number of homes a builder closed in the period -- where title actually transferred to the buyer and the sale becomes revenue. Deliveries are the homebuilder's revenue-recognition event, so they drive the quarter's reported sales. They lag orders: a home ordered today is delivered months later, so deliveries tell you about demand from prior quarters, while net new orders tell you about demand right now.
Home Gross Margin: The gross profit a builder earns on its homebuilding revenue, shown as a percentage -- how much is left after the direct cost of land and construction, before overhead and interest. Builders report a GAAP figure and often an adjusted figure that strips out inventory impairments and purchase-accounting from acquisitions; the adjusted number is non-GAAP and runs higher, so compare like with like and never a reported margin against an adjusted one.
Homebuilder Backlog: Homes that are under contract but not yet delivered at the end of the period -- revenue a builder has already sold but not yet recognized. Backlog is reported as a unit count and, usually, a dollar value. It is a cushion of near-certain future revenue, but it is not guaranteed: buyers can still cancel, so a rising cancellation rate erodes backlog before it converts to deliveries.
Hotel Occupancy: The percentage of a hotel's available rooms that were actually occupied over the period -- the volume half of RevPAR, alongside average daily rate (the pricing half). Occupancy tells you how full the hotels were, a direct read on demand, but it is read together with ADR because the two trade off: a hotel can push occupancy toward 100% by cutting rates, or protect rate while accepting lower occupancy. The most profitable operators optimize the combination (RevPAR) rather than maximizing either alone. Occupancy also has a practical ceiling near the mid-to-high 90s, so at a full hotel further RevPAR growth has to come from rate.
Hours-Per-Position Budget: The realistic number of weekly research hours an investor can sustain divided by the number of positions held, expressed as hours per position per month. A weekly budget of four hours spread across twelve positions yields roughly one hour per position per month -- insufficient to maintain a current-quality fundamental view of any business. The metric is a structural check on whether a portfolio is operating in the defensive or enterprising category, and the honest number is usually lower than investors expect.
House Money Effect: The tendency to take more risk with money that was recently won or earned through investment gains — treating it as "not really mine." Originated in gambling research but directly applies to investors who take excessive risks after a run of good returns, exposing gains to large losses.
Housing Starts: The number of new residential construction projects begun in a given month. A key economic indicator — rising housing starts create demand for lumber, appliances, and financial services. Starts are heavily influenced by mortgage rates, employment, and land availability.
HSA: Health Savings Account — a tax-advantaged account for US taxpayers with high-deductible health plans. Contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free — the only triple-tax-advantaged account in the US. After age 65, unused funds can be withdrawn for any purpose (like a traditional IRA).
Hurdle Rate: The minimum return a BDC's portfolio must earn before the external manager is entitled to an incentive fee. Typically set at 6\u20138% annualized on total assets. Below the hurdle, all income goes to shareholders. Above it, the manager earns a percentage (often 20%) of the excess. The hurdle rate aligns manager incentives with shareholder returns.
HY Spread: The premium that junk bonds pay over Treasuries. One of the best real-time gauges of market risk appetite \u2014 tightening = confidence, widening = fear.
Hyperinflation: An extreme form of inflation where prices rise so quickly — typically over 50% per month — that money loses meaningful value almost daily. Modern examples include Zimbabwe (2007-2008), Venezuela (2016-2019), and Turkey (2022). Long-running examples include Weimar Germany (1922-1923, peak ~322% per month). Hyperinflation typically destroys savings, collapses banking systems, and forces a currency reset.
Hypersupply: The phase of the real estate cycle in which demand is cooling but buildings started during the prior expansion phase are still finishing construction and delivering space. Vacancy rises and rents soften even though the buildings under construction cannot be stopped. Hypersupply typically lasts 12-24 months from the first signs of demand softening through the last delivery of in-construction inventory; the rent declines that follow are baked into the cycle by the construction lag and cannot be undone by short-term policy shifts.
