The Complete Glossary of Value Investing Terms

Value investing has its own vocabulary. Some of it is shared with finance generally; some of it is specific to the discipline that Benjamin Graham pioneered and Warren Buffett refined. Either way, if you're new to the field — or just running into a term you've seen but never had clearly defined — this is the reference you want.

These aren't dictionary definitions. They're plain-English explanations, with context for why each term matters.

A

Activist Investor

An investor (usually a fund or wealthy individual) who acquires a meaningful stake in a company and then uses that ownership position to push for changes — new management, spinoffs, buybacks, sale of the company, or other strategic shifts. Activists believe the stock is undervalued and that specific changes will unlock that value.

Asset-Light Business

A business that generates significant revenue and profit without requiring large investments in physical assets (factories, equipment, property). Software companies, financial exchanges, and franchisors are often asset-light. These businesses tend to generate high returns on capital and scale efficiently.

B

Book Value

The net asset value of a company according to its balance sheet: total assets minus total liabilities. Sometimes called "shareholders' equity." Book value is an accounting measure — it reflects historical costs, not current market values.

Value investors have long used price-to-book (P/B) ratios as a valuation tool, though its usefulness has declined as intangible assets (brands, software, intellectual property) have become a larger share of corporate value.

Business Quality

A qualitative assessment of how durable and attractive a business is. High-quality businesses have strong competitive positions, recurring revenue, pricing power, and high returns on invested capital. Value investing isn't just about buying cheap — it's about buying quality at a fair price. As Buffett famously shifted from Graham's pure "cigar butt" approach, he emphasized business quality increasingly.

C

Capital Allocation

How a company deploys its profits. The main options: reinvest in the business, acquire other companies, pay dividends, or repurchase shares. Capital allocation skill is one of the most important (and underappreciated) factors in long-term investment returns. A great business run by poor capital allocators can disappoint shareholders; a mediocre business run by exceptional capital allocators can still create substantial value.

Catalyst

An event or condition that might cause a stock's market price to converge toward its intrinsic value. Examples: earnings announcements, new product launches, industry dynamics changes, activist pressure, spinoffs, management changes. Some value investors want a catalyst before buying; others are willing to wait patiently without one.

Circle of Competence

The range of businesses and industries an investor genuinely understands well enough to make sound judgments about. Famously articulated by Buffett: knowing the boundaries of your competence is as important as the competence itself. Investing outside your circle of competence increases the odds of making errors based on incomplete understanding.

Compounding

The process of earning returns on previously earned returns. Often called the "eighth wonder of the world" (attributed to Einstein, though contested). The power of compounding is disproportionately large over long time periods and requires leaving returns in place rather than consuming them. High-quality businesses compound intrinsic value year after year, making them especially valuable as long-term holdings.

D

DCF (Discounted Cash Flow)

A valuation method that estimates a company's intrinsic value by projecting future free cash flows and discounting them back to their present value using a discount rate. The discount rate reflects the risk and opportunity cost of capital.

DCF models are useful frameworks for thinking about value, but they're highly sensitive to assumptions — especially the growth rate and terminal value. Small changes in assumptions produce large changes in the output. Use DCF as a range of values, not a precise number.

Discount Rate

In a DCF model, the rate used to convert future cash flows into today's dollars. Higher discount rates produce lower present values. Often set using the "weighted average cost of capital" (WACC) or a hurdle rate representing what the investor could earn elsewhere.

Durable Competitive Advantage

See: Moat.

E

Earnings Yield

The inverse of the P/E ratio. If a stock trades at a P/E of 15, its earnings yield is 1/15 = 6.7%. This lets you compare stock valuations to bond yields more intuitively. Joel Greenblatt uses earnings yield as part of his "Magic Formula" for stock selection.

Enterprise Value (EV)

The total value of a company, including both equity (stock market capitalization) and debt, minus cash. EV = Market Cap + Total Debt − Cash.

EV is often more useful than market cap for valuation because it reflects the true cost of acquiring the entire business. An EV/EBITDA multiple is often more comparable across companies with different capital structures than a P/E ratio.

EV/EBITDA

Enterprise Value divided by Earnings Before Interest, Taxes, Depreciation, and Amortization. A commonly used valuation multiple that allows comparison across companies with different capital structures and tax situations. Generally, lower is cheaper — though what's "low" varies significantly by industry.

F

FCF (Free Cash Flow)

The cash a business generates after paying for capital expenditures needed to maintain or grow the business. FCF = Operating Cash Flow − Capital Expenditures.

Free cash flow is what's actually available to return to shareholders (via dividends, buybacks) or deploy into new investments. Many value investors view FCF as a more honest measure of profitability than GAAP earnings, which can be distorted by accounting choices.

Float

In insurance, "float" refers to the premiums that insurance companies collect but haven't yet paid out as claims. They hold this money — often for years — and can invest it in the meantime.

Buffett has described Berkshire Hathaway's insurance float as a key source of competitive advantage: it's essentially free or low-cost capital to invest. A company with large, growing, stable float has a structural financing advantage over competitors.

More broadly, "float" can also refer to the number of publicly tradeable shares of a stock (the portion not held by insiders or strategic holders).

Franchise Value

The value above and beyond tangible assets that comes from a company's competitive position, brand strength, and earning power. A company with strong franchise value earns returns on capital above its cost of capital for an extended period.

G

Graham Number

A formula developed by Benjamin Graham to estimate the maximum price an investor should pay for a stock. Calculated as: √(22.5 × EPS × Book Value Per Share). It combines earnings and book value. The "22.5" comes from a P/E of 15 × a P/B of 1.5 = 22.5. Useful as a quick screen, though less relevant for businesses where intangible assets dominate.

I

Intrinsic Value

The "true" or "underlying" value of a business, as opposed to its current market price. Intrinsic value is based on the present value of all future cash flows the business will generate over its life.

There's no formula that produces an exact intrinsic value — it's always an estimate, always a range. Buffett has compared it to an estimate: "It's better to be approximately right than precisely wrong." The job of a value investor is to estimate intrinsic value well enough to identify when the market price is significantly below it.

L

Liquidation Value

What a company would be worth if it stopped operating and sold off all its assets to pay liabilities. Graham famously screened for "net-nets" — stocks trading below their liquidation value. This type of opportunity is rare in modern developed markets but still appears occasionally in small-caps and international markets.

Look-Through Earnings

A concept Buffett discusses in Berkshire's annual letters: the total earnings attributable to Berkshire's ownership stakes in other companies, whether or not those earnings are paid as dividends. When Berkshire owns 20% of a company that earns $100M, Berkshire's "look-through" share is $20M even if no dividends are paid.

M

Margin of Safety

The gap between a stock's estimated intrinsic value and its current market price. If you estimate a stock is worth $100 and you buy it at $60, your margin of safety is 40%.

Margin of safety is the central concept in Graham's The Intelligent Investor and arguably the foundation of value investing as a discipline. It protects against errors in your analysis, unforeseen bad events, and the inherent uncertainty of estimating future cash flows. The larger the margin of safety, the more room for error before you lose money.

Moat

A durable competitive advantage that protects a company's profits from competition. Borrowed from the analogy of a medieval castle's moat: the bigger and deeper it is, the harder it is to attack.

Warren Buffett popularized this term and has described several sources of moat:

Cost advantages: The ability to produce at lower costs than competitors
Network effects: The value of a product or service increases as more people use it (payment networks, social platforms, marketplaces)
Switching costs: Customers find it expensive or disruptive to switch to a competitor (enterprise software, banking relationships)
Intangible assets: Brands, patents, regulatory licenses, or proprietary data that competitors can't easily replicate
Efficient scale: In markets with limited demand, incumbents serve the market efficiently and entrants can't profitably add capacity

A wide-moat business earns above-average returns on capital for many years; a narrow-moat business has a temporary advantage; a no-moat business competes on price and earns mediocre returns.

Mr. Market

An allegory created by Benjamin Graham. Imagine having a business partner named Mr. Market who offers to buy your share of the business or sell you his, every single day. Sometimes Mr. Market is euphoric and quotes a high price; sometimes he's depressed and quotes a very low price.

The key insight: you don't have to accept Mr. Market's price. You can ignore it entirely. His irrationality is an opportunity, not a threat. Use his low quotes to buy; use his high quotes to sell. Never let his mood influence your view of what your investment is actually worth.

N

Net-Net

A stock trading below its "net current asset value" — current assets minus all liabilities (including long-term liabilities). This was Graham's classic deep-value screen. Net-nets are typically distressed businesses, and many fail to recover. But bought in a diversified basket, they have historically generated positive returns. Rare in large developed markets today.

O

Owner Earnings

Defined by Buffett in Berkshire's 1986 annual letter as: Net Income + Depreciation/Amortization − Capital Expenditures required to maintain competitive position − any required working capital increases.

Owner earnings represent what the business could distribute to its owner without impairing its competitive position. It's different from reported GAAP earnings and usually different from accounting cash flow. Buffett considers it the most accurate measure of a business's earning power.

P

P/E Ratio (Price-to-Earnings)

Market price per share divided by earnings per share. One of the most widely used valuation multiples. A P/E of 15 means you're paying $15 for every $1 of annual earnings.

P/E has limitations: it's backward-looking (based on trailing earnings), affected by accounting choices, and doesn't account for balance sheet differences between companies. But as a quick screen for relative cheapness or expensiveness, it remains useful.

P/B Ratio (Price-to-Book)

Market price per share divided by book value per share. Useful for capital-intensive industries (banks, insurers, industrials). Less useful for companies where intangible assets dominate.

P/FCF Ratio (Price-to-Free-Cash-Flow)

Market cap divided by annual free cash flow. Many value investors prefer this to P/E because free cash flow is harder to manipulate and more directly reflects what the business generates for owners.

Pricing Power

The ability of a business to raise prices without meaningfully losing customers. Pricing power is one of the best indicators of a strong competitive moat. Businesses with pricing power can maintain (or grow) real profitability even in inflationary environments.

R

ROIC (Return on Invested Capital)

Net operating profit after tax (NOPAT) divided by invested capital (equity + debt − excess cash). Measures how efficiently a company generates profit from the capital deployed in its business.

ROIC is one of the most important metrics in value investing. A business that consistently earns a high ROIC is compounding value internally. Over a long holding period, a business's stock return tends to converge toward its ROIC. High-quality businesses earn 15–30%+ ROIC; average businesses earn around their cost of capital; poor businesses destroy value.

ROE (Return on Equity)

Net income divided by shareholders' equity. Measures profitability relative to the equity capital in the business. Buffett has historically used high, consistent ROE as a screen for business quality.

ROE can be inflated by leverage — a company can boost ROE by taking on debt. For this reason, ROIC is often considered a more reliable indicator of business quality.

S

Scuttlebutt

An investing approach popularized by Philip Fisher in Common Stocks and Uncommon Profits. The idea: before buying a company, talk to everyone who knows it — customers, suppliers, competitors, former employees. Get a ground-level understanding of the business's competitive position, culture, and trajectory that you can't get from financial statements alone.

Stalwart

Peter Lynch's term for a large, established company with moderate but consistent growth — typically 10–12% annually. Stalwarts aren't exciting growth stocks and they're not deeply depressed value plays. They're dependable businesses that can contribute steady returns to a portfolio and are worth buying when cheap.

Sum of the Parts (SOTP)

A valuation approach for conglomerates or diversified companies: value each business unit separately and add them up to estimate total value. The result often exceeds the conglomerate's market value (the "conglomerate discount"), creating potential value-unlock opportunities through spinoffs or asset sales.

T

Terminal Value

In a DCF model, the value assigned to a business's cash flows beyond the explicit forecast period (usually 5–10 years). Terminal value typically accounts for a large portion of total estimated intrinsic value, which makes it both extremely important and extremely sensitive to assumptions.

V

Value Trap

A stock that looks cheap but stays cheap (or gets cheaper) because the business is fundamentally deteriorating. Low P/E and P/B ratios can reflect genuine cheapness — or they can reflect the market's rational recognition that the business is in trouble. The value trap is the chief hazard of mechanical, screen-based value investing without business quality analysis.

Venture Capital vs. Value Investing

Value investors focus on existing, established businesses with demonstrable cash flows. They seek to buy a dollar's worth of value for less than a dollar. Venture capitalists invest in early-stage companies with uncertain cash flows, betting on transformative upside. These are fundamentally different disciplines with different tools, time horizons, and risk profiles.

W

Working Capital

Current assets minus current liabilities. Represents the short-term capital the business uses in its day-to-day operations. Businesses that can grow with minimal working capital increases are more capital-efficient and generate more free cash flow.

Putting It All Together

Value investing isn't just about memorizing vocabulary — it's about applying these concepts to real businesses, with intellectual honesty and humility about what you don't know.

The concepts that matter most:

Intrinsic value and margin of safety (the core)
Moat (business quality)
ROIC and owner earnings (measuring what a business actually earns)
Capital allocation (what management does with the money)
Mr. Market (the right mindset for dealing with price volatility)

Get comfortable with those, and you have the foundation of the discipline.
