On Friday 16th August, 2013 NIFTY fell down by 4.08% in a single session. It was a jittery experience for investors. By this time we had shared the Rule-X performance against historical data but never analyzed against such short term events. Our team performed an analysis for the same in which we selected only NIFTY stocks. We categorized stock which has fell less than 4.08% (NIFTY fall)as good and which fell by more than 4.08% as bad. After all we have seen NIFTY gave decent returns in long term (20% during last decade). Anything doing better than NIFTY will return decent profit.
On the day the event happened, Rule-X had identified only 17 stocks on upward trend. So, Rule-X follower must have given exposure to only 17 stocks out of NIFTY 50 stocks. Our analysis revealed out of these 17 stocks 15 performed better than NIFTY. Rule-X failed on two instances. On the other hand out of 33 barred stocks by Rule-X, 8 performed better than NIFTY. In a way Rule-X failed on these 8 stocks too. However, being on conservative side, it is OK, not to invest in case of doubt. Following matrix has captured the same in visual form
