Which of the following statements is CORRECT?
A) A graph of the SML as applied to individual stocks would show required rates of return on the vertical axis and standard deviations of returns on the horizontal axis.
B) The CAPM has been thoroughly tested,and the theory has been confirmed beyond any reasonable doubt.
C) If two "normal" or "typical" stocks were combined to form a 2-stock portfolio,the portfolio's expected return would be a weighted average of the stocks' expected returns,but the portfolio's standard deviation would probably be greater than the average of the stocks' standard deviations.
D) If investors become more risk averse,then (1)the slope of the SML would increase and (2)the required rate of return on low-beta stocks would increase by more than the required return on high-beta stocks.
E) An increase in expected inflation,combined with a constant real risk-free rate and a constant market risk premium,would lead to identical increases in the required returns on a riskless asset and on an average stock,other things held constant.

The Security Market Line (SML) represents the expected return of a security or portfolio in relation to its beta with the market. An increase in expected inflation, assuming a constant real risk-free rate and a constant market risk premium, would shift the entire SML upwards uniformly. This means that both the riskless asset (which has a beta of 0) and an average stock (with a non-zero beta) would see their required returns increase by the same amount due to the inflation expectation change, assuming other factors remain constant.
