Decision Making and Common <strong>Stock</strong> Value<br />

<strong>Valuation</strong> equations measure the stock value at a point in time based on expected<br />

return and risk. Any decisions of the financial manager that affect these variables<br />

can cause the value of the firm to change. Figure 7.4 depicts the relationship<br />

among financial decisions, return, risk, and stock value.<br />

Changes in Expected Return<br />

Assuming that economic conditions remain stable, any management action that<br />

would cause current and prospective stockholders to raise their dividend expectations<br />

should increase the firm’s value. In Equation 7.4, we can see that P 0 will<br />

increase for any increase in D 1 or g. Any action of the financial manager that will<br />

increase the level of expected returns without changing risk (the required return)<br />

should be undertaken, because it will positively affect owners’ wealth.<br />

EXAMPLE Using the constant-growth model, we found Lamar Company to have a share<br />

value of $18.75. On the following day, the firm announced a major technological<br />

breakthrough that would revolutionize its industry. Current and prospective<br />

stockholders would not be expected to adjust their required return of 15%, but<br />
