接着上一个问题 解释是: Solution A is correct. Morgan’s recommendations to implement a trade that steepens the yield curve in the midst of the recession is consistent with the economic cycle. The yield curve typically steepens when the economy is in recession. But given that value stocks are likely to outperform growth stocks and that small-cap stocks are likely to outperform large-cap stocks in the immediate aftermath of a recession, Morgan’s recommendation regarding growth equities is less likely to succeed. C is incorrect because large cap stocks tend to outperform going into and during a recession, but small cap stocks tend to outperform coming out of a recession. B is incorrect because yield curves tend to steepen during a recession, so the recommendation to implement a yield curve steepening trade now is consistent with the economic cycle. 请老师解释下A正确的那一段话, 看不太懂... 谢谢!
