The plotted relationship between expected return and the level of systematic risk is called the security market line (SML). The equation of the SML is ER = Rf + (RM - Rf)Beta. Whatever your view of risk, the riskier the security, the greater the expected rate of return an investor will demand to buy and hold the security.fficeffice" />
· Movement along the SML demonstrates a change in the risk characteristics of the individual investment.
· Changes in the slope of the SML demonstrate a change in the attitudes of investors toward risk.
· Parallel shifts in the SML demonstrate changing market conditions, such as changing inflation expectations or tightening of the money supply (a change in the real risk free rate). |
