a. $30,500

b1. 27.73%

b2. Yes because the 30% margin requirement is higher than 27.73% actual

c. - 41.90%

Explanation:

a. Margin requirement at the beginning = 1,000 x 105 x 50% = $52,500

Payoff gained / (lose) from the short-sell position = (Delivery price in the position - Market price - Dividend per stock) x 1,000 = (105 - 110 - 17) x 1,000 = (22,000)

=> Remaining margin = Initial margin + Payoff from the short-sell position = 52,500 - 22,000 = $30,500

b1. Margin on the short position = Remaining margin / Values of underlying stocks in the position = 30,500 / 110,000 = 27.73%

b2. As the traders is in short position and the actual price is higher than the exercised price in the option, the margin on the short position lower than requirement (27.73% < 30%) will trigger a margin call.

c. Return on the investment equals to Pay-off from the position / initial margin requirement = - 22,000 / 52,500 = 41.90%
