GAAP: Generally Accepted Accounting Principles \u2014 the US accounting rules set by the Financial Accounting Standards Board (FASB) that all US public companies must follow in financial reporting. GAAP prioritizes consistency and comparability. Companies often disclose both GAAP and "non-GAAP" (adjusted) figures; always understand the differences, as non-GAAP adjustments can be substantial and selective.
Game Theory: The mathematical framework for analyzing strategic interactions where each participant's best choice depends on what the others do. Game theory underlies competitive dynamics in oligopolies, M&A bidding, OPEC quota negotiations, antitrust analysis, advertising arms races, and every situation where rational actors must anticipate each other. Investors who model competitive dynamics as games gain a structural read on which industries will stabilize and which will compete margins away.
Gamma: How fast Delta changes for a $1 move in the underlying. High Gamma means Delta swings quickly: an option that's near-the-money has high Gamma and its hedge ratio shifts rapidly with each price move. Long options have positive Gamma, short options have negative Gamma. Gamma is highest at-the-money near expiration.
Gamma (Options): The rate at which delta changes for a $1 move in the underlying. High gamma near expiration means a small stock move dramatically changes your position's directional exposure. Option sellers face gamma risk — their position can swing from neutral to deeply directional very quickly.
Gamma Exposure: The aggregate impact that options positioning has on a market maker's delta as the underlying price moves. Dealers with large short gamma exposure must buy more of the underlying as it rises and sell as it falls, amplifying price momentum. This flow can reinforce trends and worsen breakdowns.
Gamma Flip: The estimated underlying-asset level at which the net gamma position of options dealers flips from positive to negative (or vice versa). Below the flip line, dealers are typically net short gamma and their hedging amplifies moves; above the flip line, dealers are typically net long gamma and their hedging dampens moves. The line is ESTIMATED from public open-interest data with assumptions about dealer-vs-non-dealer positioning, so different vendors publish different lines -- estimates of the same flip can differ by 50-200 index points. A useful microstructure concept with material calibration uncertainty.
Gamma Risk: The risk that an option's delta changes rapidly as the underlying stock moves, making a hedged position suddenly directional and difficult to manage. Gamma is highest for at-the-money options near expiration. Option sellers face the greatest gamma risk because their short positions can swing from neutral to deeply in the money very quickly.
Gamma Squeeze: A rapid, self-reinforcing upward move in an underlying driven by dealer delta-hedging when call buying overwhelms put buying and pushes dealers into a heavily short-gamma position. As the underlying rises, dealers must buy more to keep their delta hedge, which pushes the price higher and forces more buying. The 2021 meme-stock episodes showcased the dynamic in single names. Gamma squeezes typically resolve as call buyers take profit, dealers unwind hedges in reverse, and the move retraces -- a reminder that the mechanism is mechanical rather than fundamental.
Gas Processing: The step where raw natural gas straight from the wellhead is run through a processing plant to strip out heavier hydrocarbons -- natural gas liquids (NGLs) like ethane, propane, and butane -- leaving pipeline-quality dry methane. Processing volumes (again in Bcf/d or BBtu/d) measure how much raw gas a midstream company treated, and the business earns fees on both the processing and the resulting NGLs. It sits between gathering (collecting raw gas from wells) and transportation (moving finished gas to market), and processing throughput is a key indicator of activity in the wet-gas basins where the NGL economics are richest.
GDP: Gross Domestic Product — the total value of all goods and services produced in a country over a period. GDP growth means the economy is expanding. Two consecutive quarters of negative GDP growth is the traditional definition of a recession.
GDP (Gross Domestic Product): The total market value of all goods and services produced within a country over a specified period, typically a quarter or year. GDP is the broadest single measure of economic health and size. Two consecutive quarters of negative GDP growth is the traditional definition of a recession.
GDP Deflator: A measure of the price level for all goods and services included in GDP, not just consumer purchases. Unlike CPI, the GDP deflator covers the entire economy including government spending and investment. It is used to convert nominal GDP growth into real GDP growth.
General Partner: The fund manager in a private equity or venture capital structure who makes investment decisions, charges management fees, and earns carried interest on profits. GPs have unlimited liability for the fund's obligations (though this is typically managed through subsidiary structures).
Geographic Mix: The percentage breakdown of a company's revenue (or, less commonly, assets) by country or region. Geographic mix matters for comp selection because emerging-market exposure carries FX risk and regulatory risk that developed-market exposure does not; a US-focused target should be compared primarily against majority-US-revenue peers, with EM-exposed peers footnoted or moved to a cross-check tier.
Geometric Growth: Growth calculated by compounding — each period's gain builds on the cumulative total, not just the original base. A portfolio that grows 10% in year 1 and loses 10% in year 2 does NOT return to the starting point (result: $99 from $100). Geometric (compound) average return is always lower than arithmetic average return whenever returns vary.
GICS: Global Industry Classification Standard — the four-level classification system (Sector → Industry Group → Industry → Sub-Industry) developed by MSCI and S&P that organizes the public stock universe into roughly comparable groups. 11 sectors at the top level. Used by index providers, ETF issuers, and institutional investors to define peer groups for valuation comparison and portfolio construction.
Gift Tax Annual Exclusion: The amount one person can give another in a year without any gift-tax reporting (around $19,000 per giver, per recipient in recent years; it is inflation-adjusted, so verify the current figure at irs.gov). 529 contributions count as gifts, so staying under the exclusion -- or using the superfunding election -- keeps them paperwork-free.
GIPS: The Global Investment Performance Standards, a voluntary set of ethical principles published by the CFA Institute for how investment firms calculate and present historical returns. The point is comparability: when a firm claims GIPS compliance it has agreed to rules that block the most common ways performance is flattered — cherry-picked accounts, quietly dropped failed funds, and returns inflated by client cash-flow timing. Treat a GIPS claim as a trust signal to look for, and its absence as a reason to ask exactly how the numbers were built.
Glide Path: The pre-set schedule a target-date fund follows to shift its mix from mostly stocks toward more bonds as the target date approaches. Far from the date it is growth-heavy; near the date it is more conservative to protect what you have built. It is an automatic, hands-off version of the time-horizon principle.
Going Concern: An audit qualifier when there is substantial doubt a company can continue operating for the next 12 months — due to losses, cash shortfalls, or debt maturity. A going concern opinion can accelerate a crisis by scaring customers, suppliers, and lenders away.
Gold Standard: A monetary system in which a currency's value is fixed to a specific amount of gold, and paper money can be redeemed for gold on demand. It limits how much money a government can create (you need gold to back it), which keeps inflation low but also removes flexibility to respond to crises. Most countries abandoned the gold standard during the 20th century; the last major link broke in 1971 when the U.S. dollar stopped being convertible to gold.
Good Debt: Debt used to acquire appreciating assets or increase earning capacity — such as a mortgage on appreciating property, a student loan for a high-return career, or a business loan. Good debt can increase net worth over time when the return on what you bought exceeds the interest rate paid.
Goodwill: The premium a company pays above the fair value of acquired assets in a merger — essentially the price paid for brand, talent, and market position. Goodwill is tested annually for impairment. A large impairment charge signals the acquisition overpaid.
Goodwill Impairment: A write-down of goodwill when the fair value of an acquired business falls below its carrying value. It is a non-cash charge but signals the acquisition destroyed value. Large goodwill impairments often coincide with CEO changes or economic downturns.
Gordon Growth Model: See: Growing Perpetuity. PV = C₁ / (r − g). The foundation under every DCF Terminal Value calculation and the entire Dividend Discount Model school of equity valuation. Named after economist Myron Gordon, who formalized the formula in 1956. Use cases: pricing utility stocks, mature dividend payers, infrastructure assets with stable cash flows. Where it breaks: growth stocks (g approaches r), companies with negative free cash flow, businesses where the perpetual-growth assumption is implausible (commodity plays, cyclicals). For those, use multi-stage DCF or comparable multiples.
GP-LP Alignment: The degree to which a PE fund's structure ties general partner economics to limited partner outcomes. Structural alignment levers include: a meaningful GP commit (1-5%+ of fund size from partner personal wealth), a high preferred return that GPs only earn carry above, a European waterfall that defers carry until fund-level performance is proven, a clawback that recovers overpaid carry, and long carry-vesting periods. Funds with weak alignment (low commit, American waterfall, no clawback, fast vest) face structural drift where GP incentives can diverge from LP outcomes.
Grahams Defensive Investor: Benjamin Grahams term for the investor who deliberately chooses to minimize the time spent on individual security selection in exchange for accepting market-average returns. The defensive category is defined by temperament and time budget, not by net worth -- a wealthy investor with no hours to dedicate to security analysis is correctly classified as defensive. The honest portfolio for this category is an index-fund-based allocation with periodic rebalancing, and Graham was direct that this is a respectable choice rather than a consolation prize for those who cannot do active work.
Grahams Enterprising Investor: Benjamin Grahams term for the investor who accepts the work of independent business analysis in exchange for the chance -- not the guarantee -- of above-average returns. The enterprising category typically requires ten or more hours per week of reading filings, tracking holdings, and monitoring positions, and it spans ten to thirty individual businesses each independently researched. Graham was explicit that the enterprising path can underperform the defensive path even after years of effort, and the choice of category should be made on grounds of temperament and time-budget honesty rather than on aspiration.
Greenshoe: A standard IPO clause (formally an "over-allotment option") that lets the underwriters sell up to 15% more shares than the original offering size. If the stock trades above the offer price after listing, the underwriters exercise the greenshoe (the extra shares are sold). If the stock trades below the offer price, the underwriters can buy shares in the open market to cover the same short position they created by overselling, which supports the price. The greenshoe is the legal mechanism that allows banks to stabilize a wobbly IPO in its first few weeks without raising market-manipulation concerns.
Grocery-Anchored Center: A multi-tenant retail center anchored by a grocery store on a long-dated lease, with inline tenants (typically restaurants, services, small specialty retail) surrounding the anchor. Grocery-anchored centers have historically been the most defensive subcategory of retail real estate because grocery is a weekly-trip purchase with very high frequency, immune to ecommerce in a way that apparel, electronics, and most general merchandise are not. Cap rates for grocery-anchored centers typically trade meaningfully below other retail subcategories reflecting the defensive profile.
Gross Gaming Revenue: The total amount a casino keeps from wagering -- what players bet minus what the casino paid back in winnings -- before any operating costs, abbreviated GGR. It is the top line of the gaming business, distinct from "net revenues" (which also includes hotel, food, and entertainment). GGR is inherently volatile because it depends on hold (how much of the money wagered the house keeps), which swings quarter to quarter with luck, especially at the high-limit table games. That is why analysts also look at a "hold-normalized" GGR that re-prices results to the theoretical hold, stripping out the luck to reveal the underlying volume trend.
Gross Lease: A lease structure in which the landlord pays all operating expenses (property taxes, insurance, maintenance, utilities, services) out of the gross rent collected. The tenant pays one number; the landlord absorbs all opex inflation, all maintenance surprises, and all tax assessments. Gross leases dominate office and multifamily and require landlord underwriting to bake in opex-inflation expectations because the landlord cannot pass those costs through to the tenant during the lease term.
Gross Margin: The percentage of revenue left after subtracting the direct cost of making the product. A company with 60% gross margin keeps $0.60 of every dollar of sales before paying for marketing, R&D, and overhead. Higher is generally better.
Gross Pay: Your total compensation before any deductions — base salary plus bonus, overtime, commissions, and the cash value of taxable benefits. The starting line on every paycheck. Net pay = gross pay minus federal/state/FICA taxes minus pre-tax contributions (401(k), HSA, health premium) minus post-tax deductions. The gap between gross and net is typically 25–35% for a salaried worker in a moderate-tax state.
Growing Perpetuity: A stream of cash flows that grow at a constant rate g forever. PV = C₁ / (r − g), where C₁ is NEXT period's cash flow (not the current one), r is the required return, and g is the perpetual growth rate. Also called the Gordon Growth Model. Two discipline checks: (1) C₁ must be the next-period cash flow — using the trailing one understates value by exactly g; (2) r > g is mandatory — if g ≥ r the formula returns infinity, signaling the perpetual-growth assumption is impossible (no company can grow faster than the discount rate forever). The mechanism: each year's incremental dividend is offset by an extra period of discounting; the algebra collapses the infinite stream into a single closed-form number.
Growth-Margin Cohort: A grouping of peer companies that share BOTH a similar revenue-growth rate (typically +/- 5 percentage points) AND a similar EBITDA-margin profile (typically +/- 5 percentage points). Two companies in the same sub-sector can still belong to different growth-margin cohorts -- a 20%-growth high-margin SaaS pure-play and a 5%-growth mid-margin SaaS pure-play do not trade in the same multiple regime, even though they share both sector and sub-sector.
