Excess Return
Excess return measures investment performance above a benchmark or risk-free rate, often used to evaluate skill, risk premia, or alpha.
Portfolio-theory terms for risk aversion, risk tolerance, risk premia, risk-free returns, excess returns, and risk-return tradeoffs.
Risk-Return Preferences and Premia terms describe portfolio theory, CAPM, beta, efficient frontiers, risk premia, volatility, exposure, and systematic versus idiosyncratic risk.
Use this branch when a model or risk concept changes how expected return, risk, diversification, beta, or portfolio efficiency is interpreted.

Excess return measures investment performance above a benchmark or risk-free rate, often used to evaluate skill, risk premia, or alpha.
Risk aversion refers to the tendency to prefer certainty over uncertainty in investment decisions, even if it might mean lower returns.
A risk premium is the additional expected return investors require for bearing risk above a risk-free benchmark.
Risk tolerance is an investor's willingness and ability to accept volatility, loss, or uncertainty in pursuit of returns.
Risk-free return is the theoretical baseline return for an investment with no default, reinvestment, or market risk.
The risk-return tradeoff describes the relationship between expected return potential and the amount of risk accepted.
