CAPM Explained - What is the Capital Asset Pricing Model? (AMZN Example)


Summary

The video delves into the intricacies of the Capital Asset Pricing Model (CAPM) to understand stock returns. It explains how the expected return on a stock is influenced by the risk-free rate, market risk premium, and beta factor, which measures market risk. By analyzing these components, investors can assess the relationship between a stock's behavior, market movements, and its valuation relative to potential risks. The discussion also touches on assets with negative correlation to the market, like gold, and how the Security Market Line aids in identifying undervalued and overvalued stocks through expected return comparisons. Ultimately, the CAPM provides a structured approach for evaluating cost of equity, supporting informed investment decisions and portfolio diversification strategies.
