Return On Equity Analysis

Return on equity analysis evaluates how much profit a company earns for each unit of shareholder equity. EP86 面子、底子、日子：财报只讲这三件事 introduces ROE through Warren Buffett’s habit of viewing stocks as a kind of variable-coupon bond, but it also warns that a high ROE can come from leverage rather than durable business quality.

E160.一个价值投资者的 20 年回顾：求积分，求胜率，求时间 adds a bank and dividend-policy use case: ROE pressure can limit payout growth, but systemically important banks may still be investable when funding-cost advantage, capital constraints, policy support, and entry price create enough Margin Of Safety.

Key Claims

• ROE is useful because it connects profit to the capital shareholders have committed.
• High ROE is stronger when it comes from margins, asset turns, and durable advantages rather than excessive debt.
• ROE should be checked against balance-sheet leverage, cash-flow conversion, and business stability.
• A single metric cannot replace Financial Statement Analysis because the same number can emerge from different business realities.
• ROE analysis should include whether dividends can grow without violating capital needs, policy constraints, or realistic nominal-growth assumptions.
• In banks, the same current profit can carry different risk depending on funding cost, risk control, and balance-sheet structure.
