Old Economy Traders opened an account to short-sell 2,600 shares of Internet Dreams at $73 per share. The initial margin requirement was 50%. (The margin account pays no interest.) A year later, the price of Internet Dreams has risen from $73 to $80, and the stock has paid a dividend of $4.00 per share. a. What is the remaining margin in the account? (Round your answer to the nearest whole dollar.) b. If the maintenance margin requirement is 30%, will Old Economy receive a margin call? No Yes c. What is the rate of return on the investment? (Round your answer to 2 decimal places. Negative value should be indicated by a minus sign.)

a. Old Economy Traders orders its broker to sell 2,600 shares of $73 per share each through short-selling.

OET account has been credited with $189,800.

OET initial margin requirement was 50%. Margin is $94,900

Therefore, total initial assets in its account is $189,800 + $94,900 = $284,700

When share price rose to $80 each, OET should buy 2,600 shares at $80 to replace its short position and it should also pay back $4 per share dividend on 2,600 shares

Therefore, total liability = $208,000 + (2,600 * $4) = $218,400

After paying off his liability, OET'S remaining margin is $284,700 - $218,400 = $66,300

b. OET's margin ratio:

Margin ratio = $66,300 / $208,000

Margin ratio = 0.31875

Margin ratio = 31.86%

It is less than the required 50%. Therefore, OET receives margin call

c. Rate of return = Return - Initial own investment / Initial own investment

Rate of return = $66,300 - $94,900 / $94,900

Rate of return = -$28,600 / $94,900

Rate of return = -0.3014

Rate of return = -30.14%

Hence, the rate of return is -30.14%
