Capital Allocation

Value

The decisions management makes about how to deploy the cash a business generates — reinvestment, acquisitions, dividends, buybacks, or debt repayment — which determine long-term shareholder value.

Warren Buffett

Capital Expenditure

Value

Money spent on acquiring or upgrading physical assets — the primary drain on free cash flow.

Capital Gain

Value

The profit from selling an investment for more than its purchase price — the difference between the selling price and the original cost basis.

Warren Buffett

Circle of Competence

Value

The domain of businesses and industries that an investor understands deeply enough to make reliable judgments about long-term competitive prospects and intrinsic value.

Warren Buffett

Comparable Company Analysis

Value

A relative valuation method that values a company by comparing its financial metrics to publicly traded peers — establishing a market-derived valuation range.

Benjamin Graham

Concentration Risk

Value

The risk that an excessive allocation to a single investment, sector, geography, or risk factor could cause outsized losses if that concentration performs poorly.

Howard Marks

Corporate Governance

Value

The system of rules, practices, and processes by which a company is directed and controlled — the mechanisms that align management decisions with shareholder interests.

Warren Buffett

Correlation

Value

The statistical measure of how two investments move in relation to each other — ranging from +1 (perfect positive correlation) to -1 (perfect negative correlation).

Howard Marks

E

EBITDA

Value

Earnings before interest, taxes, depreciation, and amortisation — a proxy for operating cash flow used widely in valuation multiples, particularly EV/EBITDA.

Warren Buffett

ESG Investing

Value

Investment approach incorporating Environmental, Social, and Governance factors alongside financial analysis — evaluating non-financial risks and opportunities that affect long-term returns.

Howard Marks

Earnings Per Share (EPS)

Value

Net profit divided by the number of shares outstanding — the portion of a company's profit attributable to each share, the denominator in the P/E ratio.

Benjamin Graham

Earnings Power Value

Value

The value of a business assuming its current normalised earnings continue indefinitely with zero growth — a conservative analytical floor distinct from growth-dependent DCF valuation.

Benjamin Graham

Earnings Quality

Value

The degree to which reported earnings accurately reflect the true economic performance and cash-generating capacity of a business.

Benjamin Graham

Earnings Yield

Value

Earnings per share divided by market price — the inverse of P/E expressed as a percentage, directly comparable to bond yields.

Benjamin Graham

Economic Moat

Value

A durable structural advantage that protects a business from competition and allows it to sustain above-average returns on capital over an extended period.

Warren Buffett

Enterprise Value (EV)

Value

Market capitalisation plus net debt (total debt minus cash) — the theoretical takeover price of a business, representing the total cost to acquire all cash flows.

Warren Buffett

Equity Risk Premium

Value

The excess return investors expect from equities over a risk-free rate — the fundamental driver of market valuations.

R

Rebalancing

Value

The periodic adjustment of a portfolio back to its target asset allocation by selling outperforming assets and buying underperforming ones — systematically buying low and selling high.

Ray Dalio

Replacement Value

Value

The cost to build or acquire the same business from scratch today — a floor valuation for asset-intensive industries.

Retained Earnings

Value

Cumulative profits reinvested in the business rather than paid as dividends — the raw material of compounding.

Return on Assets

Value

Net income divided by total assets — a measure of how efficiently a business uses its asset base to generate profit.

Return on Capital Employed (ROCE)

Value

Operating profit divided by capital employed (total assets minus current liabilities) — measures how efficiently a business generates profit from all capital deployed in the business.

Warren Buffett

Return on Invested Capital (ROIC)

Value

Operating profit after tax divided by total capital employed — the single most revealing measure of whether a business creates or destroys economic value.

Charlie Munger

Return on Investment (ROI)

Value

The percentage gain or loss on an investment relative to its cost — total return (including dividends and price appreciation) divided by the amount invested.

Warren Buffett

Reverse DCF

Value

A valuation technique that asks what growth rate the current market price implies, revealing the expectations embedded in the stock price rather than projecting cash flows forward.

Warren Buffett

Risk-Free Rate

Value

The theoretical return on an investment with zero risk — typically the 10-year government bond yield.
