If an investor buys 100 shares of a $50 stock on margin when the initial margin requirement is 40%, how much money must she borrow from her broker? A. $3,000. B. $2,000. C. $4,000.
An initial margin requirement of 40% would mean that the investor must put up 40% of the funds and brokerage firm may lend the 60% balance. Therefore, for this example (100 shares) * ($50) = $5,000 total cost. $5,000 * 0.60 = $3,000.
