Sam buys 100 shares of stock at $50/share. The stock has been paying a $0.25 quarterly dividend. The company earnings increase by 10%, and the company declares that the dividend will increase by 5% for the year. Sam sells the stock at $53. What is the total return if he holds the stock one year?
HPR = ($53 + $1.05 - $50) / $50 = 8.1%
The $0.25 dividend increases by 5% to $0.2625. The yearly dividend is $0.2625 x 4 = $1.05. You can calculate per share.
A client uses a 5-year time horizon to buy stocks that are volatile. He has a 12% required rate of return. If the stock is first up 10% (1st year), up 30% (2nd year), no change (3rd year), down 15% (4th year), up 20% (5th year), did he make his required rate of return over the 5 years?
1.10 x 1.30 x 1 x 0.85 x 1.20 = 1.4586
