You buy 100 shares of stock at $60 per share. You borrow $2,000 on margin (less than the maximum amount). The initial margin is 55% and the maintenance margin is 30%. The price of the stock increases to $90 per share. Calculate your percentage gain or loss. [Two ways to calculate this, either way is fine. Since you did not borrow the maximum amount, your initial margin was 66.67%.]
