We are now able to apply these concepts to determining the value of different securities. In particular, we are concerned with the valuation of the firm’s long-term securities – bonds, preferred stock, and common stock (though the principles discussed apply to other securities as well). | Chapter 5 Risk and Return © 2001 Prentice-Hall, Inc.

What return was earned over the past year? Return Example The stock price for Stock A was $10 per share 1 year ago.

Does it matter if it is a bank CD or a share of stock? The variability of returns from those that are expected. Determining Expected Return (Discrete Dist.) R = S ( Ri )( Pi ) R is the expected return for the asset, Ri is the return for the ith possibility, Pi is the probability of that return occurring, n is the total number of possibilities. n i=1 How to Determine the Expected Return and Standard Deviation Stock BW Ri Pi (Ri)(Pi) .10 .20 .09 .40 .036 .21 .20 .042 .33 .10 .033 Sum .090 The expected return, R, for Stock BW is .09 or 9% Determining Standard Deviation (Risk Measure) s = S ( Ri - R )2( Pi ) Standard Deviation, s, is a statistical measure of the variability of a distribution around its mean. It is the square root of variance. Note, this is for a discrete distribution. n i=1 How to Determine the . | Chapter 5 Risk and Return © 2001 Prentice-Hall, Inc.
