What to Check

Check the model assumptions, benchmark market portfolio, beta estimate, volatility window, covariance inputs, risk premium, risk tolerance, exposure definition, and whether the model is descriptive or prescriptive.

Common Mistakes

  • Using model output without checking assumptions.
  • Treating beta, volatility, and total risk as interchangeable.
  • Assuming efficient-frontier analysis eliminates estimation error.
  • Calling a return excess without defining the benchmark or reference rate.

Excess Return

Excess return measures investment performance above a benchmark or risk-free rate, often used to evaluate skill, risk premia, or alpha.

Risk Aversion

Risk aversion refers to the tendency to prefer certainty over uncertainty in investment decisions, even if it might mean lower returns.

Risk Premium

A risk premium is the additional expected return investors require for bearing risk above a risk-free benchmark.

Risk Tolerance

Risk tolerance is an investor's willingness and ability to accept volatility, loss, or uncertainty in pursuit of returns.

Risk-Free Return

Risk-free return is the theoretical baseline return for an investment with no default, reinvestment, or market risk.

Risk-Return Tradeoff

The risk-return tradeoff describes the relationship between expected return potential and the amount of risk accepted.
