Review Questions

• How did John Lintner's work enhance the understanding of risk and return relationships in financial markets?
  • John Lintner enhanced the understanding of risk and return by formalizing the Capital Asset Pricing Model (CAPM), which established a clear linear relationship between an asset's expected return and its systematic risk, represented by beta. His work illustrated that investors can expect higher returns from assets with greater risk, thus allowing for more informed investment decisions. This framework has become foundational in modern finance, aiding investors in evaluating the trade-offs between risk and expected return.
• In what ways did Lintner's CAPM contribute to portfolio management strategies?
  • Lintner's CAPM contributed to portfolio management strategies by providing a systematic approach to evaluating investments based on their risk-adjusted returns. By utilizing beta, investors could better understand how individual assets would perform relative to market movements, enabling more effective diversification. This allowed portfolio managers to construct portfolios that optimize expected returns while managing overall risk exposure, leading to improved investment performance.
