问题如下：
A three-month equity forward contract’s price is $121.2341, the underlying spot price is $120. The annually compounded risk-free rate is 2%, assume no dividend paid. Which of the following is correct?
选项：
A. There is no arbitrage opportunity
B. There is a carry arbitrage opportunity
C. There is a reverse carry arbitrage opportunity.
解释：
B is correct.
考点：equity forward contract的无套利估值。
解析：
无套利下的FP
现在市场中的forward price被高估，所以应该买入现货并持有，卖出forward contract，即carry arbitrage，因为carry了现货
如果是卖出现货，买入forward，则是reverse carry，因为没有carry现货。
题中的carry是什么意思？
