1. You just bought 200 shares of a stock priced at $45 per share using 50% initial margin. The broker charges 5% annual interest rate on the margin loan and requires a 30% maintenance margin. One year later stock price dropped to 29 and you recieved margin call, to restore your margin to the initial margin level, how much would you need to deposit?
2. You short-sell 200 shares of Tommy co. now selling for $37 per share. If you wish to limit your loss to $1,450, you should place a stop-buy order at what price?
3. You purchased 250 shares of common stock on margin for $50 per share. The initial margin is 65% and the stock pays no dividend. Your rate of return would be how much if you sell the stock at $35 per share. Ignore interest on margin.
