overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
The cost of equity as modeled by the Capital Asset Pricing Model (CAPM) is a financial metric used to estimate the return that investors require for holding a company's equity, considering its risk relative to the market. It combines the risk-free rate, the stock's beta coefficient (which measures volatility compared to the market), and the expected market return to determine an appropriate rate of return on equity investments. This concept is fundamental in corporate finance for valuation, cost of capital calculations, and investment decision-making.
