The stock of Nogro Corporation is currently selling for $25 per share. Earnings per share in the coming year are expected to be $2. The company has a policy of paying out 40% of its earnings each year in dividends. The rest is retained and invested in projects that earn a 8% rate of return per year. This situation is expected to continue indefinitely.

Assuming the current market price of the stock reflects its intrinsic value as computed using the constant-growth DDM, what rate of return do Nogros investors require? (Do not round intermediate calculations.)

Required Return=? I got 6.4% but it was incorrect
