Suppose an investor is optimistic on ABC stock, which is currently selling at $$100$ per share with the initial margin requirement of $50\%.$ The investor has $$5,000$ to invest borrowing the maximum remaining from the broker, and expects the stock to go up in price by $30\%$ during the next year. Ignoring any dividends and commissions, the expected rate of return on the investment would be:

$30\%$

$40\%$

$50\%$

$60\%$
