Harmony Shadwell wants to buy 100 shares of Google, which is currently selling in the market for $56 a share. Rather than liquidate all her savings, she decides to borrow through her broker. Assume that the margin requirement on common stock is 50%. If the stock rises to $66 a share by the end of the year, show the dollar profit and percentage return that Harmony would earn if she makes the investment with 50% margin. Contrast this to what she'd make if she uses no margin. Assume 9% interest on the borrowed money.
