1. An investor is bearish on a stock whose market price is K100 per share. He instructs his broker to sell short 1000 shares who borrows the 1000 either from another customers account or from another broker. Suppose the broker has a 50% margin requirement on short sales, how would the investors account look like? Supposing the share price drops to K70, how would the account look like? Supposing the broker has a maintenance margin of 30% on short sales, how much can the share stock rise before you get a margin call? Construct a balance sheet if the share price goes up to K110. If the short position maintenance margin is 40%, how far can the stock price rise before the investor gets a margin call?
