The price of gold is currently $1,700 per ounce. The forward price for delivery in one year is $1,800. An arbitrageur can borrow money at 4% per annum.
a) What should the arbitrageur do?Assume that the cost of storing gold is zero and that gold provides no income.
b) Is this a true arbitrage trade?
c) What other risks should you consider?
套利者借1700购买黄金，利息成本是68元，如果一年后以1800元卖掉黄金，赚了32元，一年后价格上涨，但是为什么是short forward contracts?short 和long应该怎么判断呢？
