NAHB Housing Market Index: A monthly survey of US homebuilders rating current sales conditions, sales expectations, and prospective buyer traffic. Above 50 means more builders view conditions as good than poor. A leading indicator for residential construction and lumber/building materials demand.
Naive Diversification: The mistaken belief that holding many positions IS the same as being diversified, regardless of how those positions correlate. A portfolio of 25 US large-cap stocks across 8 sectors has roughly the same drawdown profile as 1 US large-cap ETF when correlations rise during market stress. True diversification (Markowitz, 1952) requires adding low-correlation positions across distinct risk factors — not just adding more positions within the same factor.
Narrative Fallacy: The human tendency to construct a plausible causal story around random or statistical events, and to trust that story over base-rate evidence. Coined by Nassim Taleb in "The Black Swan" (2007). In investing, narrative fallacy drives the overpricing of "story stocks" with compelling but already-priced narratives, and the underpricing of boring compounders with strong fundamentals and no exciting headline.
Nash Equilibrium: An outcome in a strategic game where no player can improve their result by changing strategy unilaterally, given the strategies of the others. The Nash equilibrium is the stable resting point competitors converge to — and it is often WORSE for everyone than a cooperative outcome that nobody can credibly commit to. The prisoner's dilemma is the canonical example: both players defect at the Nash equilibrium even though both-cooperate would jointly be better.
National Debt: The total amount a government owes from accumulated budget deficits over time. US national debt exceeds $34 trillion. It is most meaningfully measured as a percentage of GDP to allow cross-country comparison and historical context.
National Income Identity: Y = C + I + G + NX. The accounting truism that total output (Y, real GDP) equals the sum of consumption (C), investment (I), government spending (G), and net exports (NX = exports minus imports). The identity holds every period by construction -- every dollar of output must be bought by someone in one of those four buckets. The identity is the constraint that every macro policy debate runs into: any claim that all four components can move favorably at once without something else giving must be reconciled with the arithmetic.
NAV per Share: Net Asset Value per share -- an estimate of what a REIT's underlying real estate would be worth if sold at current private-market prices, net of debt, divided by shares. Because REIT properties are carried on the balance sheet at depreciated historical cost (often far below market value), NAV is a market-based alternative to book value, and REITs frequently trade at a premium or discount to it. A persistent discount to NAV can signal the market doubts management or expects property values to fall; a premium signals confidence. It is an estimate (analyst- or management-derived), not an audited figure, so treat it as directional.
NAV Premium/Discount: When an ETF trades above NAV, it's at a premium; below NAV, it's at a discount. Most liquid ETFs trade within 0.1% of NAV thanks to the creation/redemption mechanism.
NBBO: National Best Bid and Offer -- the highest bid and lowest ask currently posted across every US equity exchange, consolidated by the SIP (Securities Information Processor). The NBBO is the headline quote you see on a ticker page. Brokers are required under Reg NMS to fill marketable retail orders at the NBBO or better, which is the basic best-execution protection retail orders enjoy in US equities.
Negative Convexity: When a bond's price gains from falling rates are smaller than its price losses from rising rates — an asymmetric and unfavorable curvature. Callable bonds and mortgage-backed securities exhibit negative convexity near their call or prepayment price because the issuer or homeowner will refinance when rates fall.
Negative Leverage: When borrowing costs exceed the cap rate — so debt reduces your cash return on equity. Taking on a 7% mortgage for a property generating a 5% cap rate is negative leverage. Common in low-cap-rate markets with rising rates, which reduces returns for highly leveraged investors.
Negative Pledge: A covenant preventing a borrower from pledging its assets as collateral for new debt, protecting existing unsecured creditors from being structurally subordinated. Violating a negative pledge clause is an event of default. The clause effectively limits the company's ability to issue senior secured debt that would jump ahead of existing holders.
Negotiated Transaction: An M&A deal structured through bilateral negotiation between one buyer and one target, distinct from a structured auction. Negotiated transactions often arise from pre-existing strategic relationships, activist-driven situations, or hostile bids that turn friendly. The contractual machinery (standstill, no-shop, fiduciary-out, matching rights, break fee, Revlon duties) governs how the deal can be modified or topped after signing.
Net Asset Value: The per-share book value of a fund or BDC: total assets minus total liabilities divided by shares outstanding. For BDCs, NAV is the most important anchor for valuation — a BDC trading at a discount to NAV implies the market prices the portfolio below cost; a premium implies confidence in the manager's ability to generate returns above book.
Net Asset Value (NAV): The per-share value of an ETF's underlying holdings. Calculated daily by dividing total assets minus liabilities by shares outstanding. ETFs trade at prices that may differ slightly from NAV.
Net Book Value: The original cost of an asset minus all accumulated depreciation recorded so far. A machine bought for $1 million with $400,000 in accumulated depreciation has a net book value of $600,000. This is the balance sheet value — not necessarily market value.
Net Cash: Cash on hand minus total debt. Positive = more cash than debt (financially strong). Negative = the company owes more than it has in liquid reserves.
Net Charge-Off: NCO. Actual loan losses written off the books during the period, net of any recoveries on previously charged-off loans. While loan-loss provisions are managements estimate of future losses, NCO is the reality check -- the realized losses now hitting the income statement. Comparing the trajectory of provisions to the trajectory of NCO tells you whether management is building reserves (provisions exceed NCO) or releasing reserves (NCO exceeds provisions). NCO as a percentage of average loans is the standard credit-quality benchmark across the banking industry.
Net Charge-Off Rate: The value of loans a bank gave up on as uncollectible during the period (charge-offs, net of any later recoveries), annualized as a percentage of its average loans -- the realized-loss rate on the loan book. It is the clearest read on actual credit quality: a low, stable NCO rate (well under 1% for a diversified lender) signals a healthy book, while a rising rate is the concrete evidence that loans are going bad, usually showing up first in credit cards and commercial real estate. Read it alongside the loan-loss reserve: a bank whose charge-offs are climbing toward or past what it has reserved may need to take a larger provision, which hits earnings.
Net Current Asset Value: NCAV. Current assets minus all liabilities including long-term debt, divided by shares outstanding. NCAV approximates what shareholders would receive if the company were liquidated tomorrow at carrying values, after every creditor was paid in full. A stock trading below two-thirds of NCAV is buying current assets at a discount and receiving the entire long-term business for free -- the original quantitative basis of Grahams cigar-butt strategy.
Net Exports: Exports minus imports of goods and services. A trade surplus (positive net exports) adds to GDP; a trade deficit (negative net exports) subtracts from it. The United States has run persistent trade deficits for decades, importing more than it exports.
Net Flows: New client money coming in minus money withdrawn, over the period -- the organic growth engine of an asset manager, stripping out the effect of markets rising or falling. Positive net flows mean the firm is winning more assets than it is losing, which compounds fee revenue durably; persistent net outflows are the central risk for a traditional manager, because they shrink the fee base regardless of how markets perform. Read net flows alongside AUM growth to separate genuine franchise strength from a passive market tailwind.
Net Income: The bottom line: total revenue minus all expenses, taxes, and interest payments. What the company actually earned for shareholders during the period. Can be distorted by one-time items, accounting choices, and tax timing. Always read alongside cash flow to confirm quality of earnings.
Net Interest Income: The total interest a bank earns on its assets (loans, securities) minus the total interest it pays on its liabilities (deposits, bonds, other borrowings). NII is the dollar amount, while NIM is the percentage. NII grows when the asset book expands AND when the spread widens; NII can grow while NIM compresses if the balance sheet grows fast enough, which is one reason bank investors should always look at both numbers together.
Net Interest Margin: NIM. A banks net interest income divided by its average earning assets, expressed as an annualized percentage. NIM measures how much spread the bank captures on its core borrow-short-lend-long business, after netting the interest paid on deposits and other liabilities against the interest earned on loans and securities. Widening NIM signals an improving spread environment (typically a steepening curve and rising rates with sticky deposits); compressing NIM signals the opposite. NIM is the single most important profitability metric for traditional banks.
Net Investment Income: Interest income, dividend income, and fee income earned on investments, minus operating expenses. For BDCs, NII is the primary driver of the dividend. A coverage ratio of NII / dividend above 1.0 means the dividend is fully covered by recurring income. Watch for fee waivers that temporarily inflate coverage.
Net Leverage: Net Debt (total debt minus cash) divided by EBITDA \u2014 the primary leverage metric in credit analysis and loan covenants. Below 2x is conservative, 2-4x is moderate, above 4x is heavily leveraged. Negative means net cash.
Net Margin: What percentage of revenue the company keeps as actual profit. Expanding margins = improving efficiency. Shrinking margins = rising costs or pricing pressure.
Net New Orders: The count of new home-sale contracts a builder signed during the period, minus any that buyers cancelled -- the forward-demand signal. Today's net orders become tomorrow's deliveries and revenue, so a builder can look healthy on current deliveries while orders are already rolling over. Read net orders together with the cancellation rate and the absorption pace to judge whether demand is strengthening or softening.
Net of Fee IRR: The IRR realized by limited partners after deducting all GP fees (management, transaction net of offset, fund expenses) and carried interest. Distinct from GROSS IRR, which is the IRR at the portfolio-company level before any GP economics. Net IRR is the only meaningful metric for evaluating an LP's return on a fund investment; gross IRR flatters the GP's reported performance. Net-to-gross spread is typically 400-700 bps depending on the fee structure, with high-fee / low-offset funds running the wider spread.
Net Operating Income (NOI): A property's annual rental income minus operating expenses (maintenance, insurance, property taxes, management fees) — but before debt service and depreciation. NOI is the numerator in cap rate calculations and the primary measure of a property's operating performance.
Net Operating Loss (NOL): A tax loss from a prior period that can be carried forward to offset future taxable income, reducing future tax bills. NOL carryforwards are recorded as deferred tax assets. They expire after a set number of years if not used, so their realizability must be assessed annually.
Net Pay: Take-home pay — gross pay minus all deductions (federal/state/FICA tax withholding, pre-tax 401(k)/HSA contributions, health insurance premium, post-tax deductions). The number that hits your bank account. A $90K salary in California typically nets ~$5,200/month after maxing 401(k) match + standard health coverage; the gap from gross is the single most-misunderstood part of a first paycheck.
Net Premiums Earned: The portion of premium an insurer has actually earned during the period as coverage elapsed -- premiums written are recognized as earned gradually over the policy term (a 12-month policy earns one-twelfth of its premium each month). Net premiums earned is the revenue figure that pairs with the period's losses to produce the loss ratio and combined ratio. The gap between premiums written and premiums earned is a timing signal: when written runs ahead of earned, the insurer is growing and building an unearned-premium reserve that will convert to future revenue.
Net Premiums Written: The total premium an insurer sold during the period, net of the premium it ceded to reinsurers -- the top-line measure of how much new business the insurer took onto its own books. "Written" means booked when the policy is sold, before it is earned over the life of the policy. Growth in net premiums written is the clearest read on whether an insurer is expanding, and its direction relative to pricing tells you whether growth is coming from rate increases (healthy in a hard market) or from writing more risk (which can be a warning if pricing is soft).
Net Realizable Value: The estimated selling price of an asset minus the costs needed to prepare it for sale. For inventory, NRV is the ceiling for carrying value — if NRV falls below cost, the inventory must be written down. A key concept in the lower-of-cost-or-market rule.
Net Unit Growth: The year-over-year percentage change in a retailer's store count, net of closures -- new stores opened minus stores closed, as a growth rate. For discount and dollar-store chains, whose model is built on blanketing the country with thousands of small-format locations, net unit growth is a core driver of total revenue growth on top of same-store sales. It is the "more stores" lever, distinct from the "more per store" lever that comps measure. Watch for a slowing unit-growth rate at a maturing chain, and for closures rising at a struggling one, both of which signal the store-expansion runway is shortening.
Network Effects: A competitive moat where a product or service becomes more valuable as more people use it. Visa's payment network, social media platforms, and marketplace businesses (Airbnb, eBay) exhibit network effects. Strong network effects create a virtuous cycle: more users attract more users, compounding the advantage and raising the barrier to competition.
NGL Fractionation: The final separation step in the natural-gas-liquids chain: a fractionation plant takes the mixed NGL stream that came out of gas processing and splits it into its pure, sellable components -- ethane, propane, normal butane, isobutane, and natural gasoline -- each of which has its own market and price. Fractionation volumes (in barrels per day) measure how much mixed NGL a company separated into purity products. It is a fee-based, toll-like business concentrated at hubs such as Mont Belvieu, Texas, and rising fractionation volumes signal growing NGL production feeding into petrochemical and export demand.
Nominal Return: The headline rate of return on an investment — the percentage gain in dollars before accounting for inflation. A savings account paying 4.5% APY delivers a 4.5% nominal return. The nominal return is what banks and brokers advertise; the real return (Nominal − Inflation) is what your purchasing power actually does.
Nominal Yield: A bond yield expressed in current-dollar terms, BEFORE any inflation adjustment. Standard Treasury yields, corporate yields, and most bond quotes are nominal. The nominal yield equals real yield plus expected inflation plus an inflation risk premium. Comparing nominal yields across bonds with different durations or credit profiles is the standard market comparison; comparing nominal-vs-real (nominal Treasury vs TIPS) is how the market reveals its expectation of future inflation.
Non-Accrual: When a BDC stops recognizing interest income on a loan because the borrower has missed payments or the investment is at severe risk of principal loss. Non-accrual loans are valued at fair value and typically written down. A rising non-accrual rate is the most direct warning sign of portfolio deterioration and dividend coverage risk.
Non-Cash Charge: An accounting expense that reduces reported earnings but does NOT actually cause cash to leave the company. Depreciation and amortization are the main examples. Stock-based compensation is another — it dilutes shareholders but does not consume cash. Non-cash charges are added back in the cash flow statement and in EBITDA calculations.
Non-Interest Income: Bank revenue that does not come from the rate spread on lending. Common sources include credit card interchange fees, wealth management fees, investment banking advisory and underwriting fees, mortgage banking gains, deposit service charges, and trading revenue. A higher share of non-interest income diversifies a bank away from pure rate-cycle exposure, but can introduce different risks (trading losses, market-volume sensitivity, regulatory action against fee categories).
NOPAT: Net Operating Profit After Taxes. The after-tax operating profit a business would generate if it had no debt -- EBIT multiplied by (1 minus tax rate). NOPAT is the operating-profit numerator of ROIC (NOPAT divided by invested capital) and the cash-flow input to economic profit (NOPAT minus the capital charge). The metric strips out financing decisions to isolate the operating performance of the business, which is what the value-driver framework analyzes.
Notional: The reference principal amount underlying a derivatives contract used to calculate payment obligations. In a $100 million interest rate swap, $100 million is the notional — no cash changes hands in that amount; it merely determines the size of periodic interest payments. Notional exposure across a derivatives book can dwarf actual capital at risk.
Notional Amount: The face value underlying a derivative contract used to calculate payment amounts. The notional is not exchanged between counterparties — it is simply the reference principal. A $100 million interest rate swap with a 1% fixed rate implies $1 million in annual payments.
Notional Value: The face value of a derivatives contract — the reference amount used to calculate payment obligations. A $10 million interest rate swap has $10 million notional value. The notional is rarely exchanged; it's just the measuring stick for payment calculations.
NPV: Net Present Value — the sum of an investment's future cash flows discounted to today at the cost of capital, minus the initial outlay. Positive NPV means the project earns more than its capital costs and creates value; negative NPV destroys value. NPV is the theoretically correct decision rule for capital allocation: when comparing options, take the highest positive NPV, not the highest IRR. Mechanically, NPV is just per-period discounting summed across an uneven cash-flow stream: NPV = −Initial + Σ CFₜ/(1+r)ᵗ for each year t. This is the engine under every DCF valuation; the same arithmetic that prices a project also prices a business or a stock.
