The Beta of the stock/security is also used for measuring the systematic risks associated with the specific investment. Thus, as can be seen above, Security A has a lower beta therefore, it has a lower expected return while security B has a higher beta coefficient Beta Coefficient The beta coefficient reflects the change in the price of a security in relation to the movement in the market price. The expected return for Security A as per the security market line equation is as per below. Expected return = (p1 * r1) + (p2 * r2) + ………… + (pn * rn), where, pi = Probability of each return and ri = Rate of return with probability. Now let’s understand the security market line example, calculating the expected return Calculating The Expected Return The Expected Return formula is determined by applying all the Investments portfolio weights with their respective returns and doing the total of results. Consider two securities, one with a beta coefficient of 0.5 and other with the beta coefficient of 1.5 with respect to the market index.

Let the risk-free rate by 5%, and the expected market return is 14%.

The assets which are below the SML are overvalued as they have lower expected returns for the same amount of risk.

The assets above the SML are undervalued as they give the higher expected return for a given amount of risk.

All the assets which are correctly priced are represented on SML.

Higher the market risk premium steeper the slope and vice-versa

The slope of the Security Market Line is determined by market risk premium, which is: (E(R M) – R f).

Zero-beta security or zero-beta portfolio has an expected return on the portfolio, which is equal to the risk-free rate.

SML is a good representation of investment opportunity cost, which provides a combination of the risk-free asset and the market portfolio.
