问题如下：
Johnson research an equity strategy involving two large Electric vehicle companies, Z and T. Johnson recently participated in a trade show where he inspected Z’s newestelectric car. Based on information from the trade show and other analysis conducted by Johnson, He concludes that Z will not be able to meet its revenue expectations. Current valuation metrics indicate that Z shares are overvalued relative to shares of T. Johnson decides to take a short position in Z and a long position in T with equal beta-weighted exposure.
which equity hedge fund strategy best describes the Z and T positions taken by Johnson?
选项：
A.Short bias
Long/short equity
Equity market neutral
解释：
C is correct.
C是正确的。 Johnson 决定做空 Z 并在 T 中持有相同的 beta 加权敞口的多头头寸是pairs trade或EMN的一个例子。 Johnson 通过构建预期投资组合 Beta 为零的策略来抵消市场风险。由于他的策略不承担贝塔风险并试图抵消许多其他因素风险，Johnson 必须对多头和空头头寸应用杠杆，以从选股中获得有意义的预期回报。
A 不正确，因为在Short bias中，基金经理旨在出售价格昂贵的股票，但可能会在空头敞口与一些适度的长头敞口之间取得平衡。然而，Johnson 已进入EMN配对交易，该交易采取相反的多头和空头头寸，试图消除市场敞口。他的仓位没有空头倾向。
B 是不正确的，因为long/short equity strategies基金经理买入他们预期会上涨的公司的股票，并卖出他们认为价值会下跌的公司的股票。当多头头寸和空头头寸一起放入投资组合时，市场敞口是经贝塔调整的多头和空头敞口的净值；然而，目标贝塔值通常不为零。 Johnson 通过构建预期投资组合 Beta 为零的策略来抵消市场风险。
如题
