When we compare FBMKLCI with S&P500, we can see that when S&P500 rallied strongly and FBMKLCI went the opposite direction (in September to November 2017), the subsequent pullback in S&P500 coincided with a strong rally in FBMKLCI. If this were to repeat, a possible pullback in S&P500 in the weeks ahead could be followed by a decent recovery rally in FBMKLCI.
