CAPM

Capital Asset Pricing Model

A formula to estimate the return shareholders expect, based on market risk.

Detailed explanation

CAPM adds a risk premium to the risk-free rate, scaled by the stock's beta.

Formula

Ke = Risk-free rate + Beta × (Market return − Risk-free rate)

Example

Rf 7%, beta 1.2, equity risk premium 6% → Ke = 7 + 7.2 = 14.2%.

Why it matters

Standard way to get cost of equity for WACC.

Key points

  • Uses beta as the only risk measure.
  • Risk-free rate often a government bond yield.
  • Inputs are estimates.
