哪里能看出保证金是50%？

问题如下：

Assume a broker provides a margin loan to a U.S. hedge fund that puts up the minimum equity amount required by the Federal Reserve. If the hedge fund wants to take a $250,000 equity position, determine the margin loan amount and the leverage ratio of this position.

选项：

A.

Margin loan = $125,000; leverage ratio = 1.0.

B.

Margin loan = $125,000; leverage ratio = 2.0.

C.

Margin loan = $250,000; leverage ratio = 0.0.

D.

Margin loan = $250,000; leverage ratio = 1.0

解释：

美联储要求的初始保证金比例是50%（即，保证金折扣率为50%）。因此，保证金贷款额将是125,000美元（= 250,000美元 × 50%）。杠杆比率等于总资产除以净资产。所以，这家对冲基金的杠杆比率为2.0（= 250,000美元 / 125,000美元）。
