Federal Reserve Reg T mandates that you can borrow up to 50% of the price of securities you buy from your broker. Suppose you buy 100 shares of IBM stock at $135 per share, borrowing the full 50% from your broker at 2% interest per year. After 1 year, suppose IBM stock increases in value by 10% in value and pays no dividend. What is the closest to your return assuming you receive no margin calls during the year?
