不是fundamental long/short吗

问题如下：

A money manager was reviewing the automobile sector and identified that the stock of General Motors (GM) is relatively overvalued compared to Ford. A money manager purchases 100 shares of Ford and shorts 150 shares of GM. It turned out that the manager’s perception was right. At the end of the quarter, she unwinds both positions, making a profit on both positions. What is this strategy called?

选项：

A.Equity long/short

B.Event driven

C.Relative value

解释：

Equity long/short strategies purchase undervalued stocks and sell short overvalued stocks. Event-driven managers (Choice B) participate in such events as mergers and spin-offs. Relative value managers (Choice C) seek to arbitrage values between related securities.

题目中GM和福特是两个相关度非常高的公司，现在GM被高估，福特被低估，所以基金经理就买福特，卖GM，这是一个很典型的equity策略。

其中C选项relative value主要是可转债、债券之间的套利。
