这道题也没说主语是50-day的啊,我还以为是200-day那个。所以怎么区分问题问的是哪一个?

问题如下:

A trader observes that the 50-day moving average for the S&P 500 Index recently crossed below its long-term 200-day moving average. This situation is referred to as a:

选项:

A.

death cross.

B.

golden cross.

C.

Bollinger Band.

解释:

A is correct.

A widely followed moving average crossover signal is the one that takes place between the 50-day moving average and the 200-day moving average. When the short-term (50-day) moving average crosses below the long-term (200-day) moving average, it is called a death cross and is a bearish signal.

嗨,爱思考的PZer你好:


金叉和死叉都是说短期移动平均线穿过长期移动平均线的状态。这道题说的是50日的移动平均线穿到了200日移动平均线下方,那么这是个死叉。
