your margin account requires: 1) an initial margin of 50%. 2) a maintenance margin of 30%. A share in Miller Moore Equine Enterprises (WHOA) is selling for $50. You have $20000, and you want to buy as much WHOA as you can. After your purchase, shares of WHOA fall to $35. What is your new margin? Will you be subject to a margin call? If yes, how much money will you have to deposit to cover the margin call?
