Investors in stocks have different appetites for risk. Data on 12 monthly returns, ye, of a technology stock are collected in parallel with monthly returns of the relevant market portfolio (representing a stock index), Tt. According to the capital asset pricing model (CAPM), the relationship can be expressed as: Ye=+BI++ Et where a is the risk-free rate of return, B is the systematic risk (i.e. the risk the stock shares with the market), and E is the usual regression error term.
