Introduction to the Portfolio Approach

Risk, return, diversification, and the main portfolio management styles.

Chapter 15 introduces the portfolio perspective that drives the rest of Exam 2. It moves from single-security thinking to portfolio-level risk and return, diversification, and the broad styles used by portfolio managers.

Students should pay attention to what changes when assets are held together. The exam often tests whether a position that looks risky on its own can still improve a portfolio because of correlation, diversification, or style fit.

Exam Focus

  • Distinguish total risk, systematic risk, and diversification effects in a portfolio setting.
  • Explain why expected return must be assessed together with volatility, correlation, and portfolio role.
  • Compare manager styles such as active and passive, top-down and bottom-up, and growth and value.
