Answer:
What the investors will do depends on whether the actual return will be higher, lower or the same as the required return (Opportunity cost of capital) .
The Actual return can be calculated using the Holding Period Return which is;
= (Earnings(Dividends) + (Ending Stock Price - Beginning Stock Price))/Beginning Stock Price
= (2 + (52 - 50))/50
= 4/50
= 8%
The Opportunity Cost of Capital can be calculated using CAPM.
= Risk Free Rate + beta(Market Premium)
= 4% + 0.75(7%)
= 9.25%
The Opportunity Cost of Capital is greater than the Actual Return from the stock so the stock is a bad buy.
Investors will not invest.
