S&P 500 Chart – 14 Day RSI Chart
As illustrated below, the current reading is the 3rd highest since 2010, and the highest since April of that year. We went ahead and analyzed the historicial forward returns to see how markets have reacted to extermely high levels of momentum.
We focused on the top 10 readings which highlighted to us that returns over the next 3 days were positive on no occasions, and averaged -.69%. The worst return was a mere 1%, which is nothing to panic about. Over a 7 day trading period, and a 20 day trading period, the returns are fairly neutral. Over a 7 day period the returns averaged -.34%, finishing positive 67% of the time, and the worst return being -3.95%. Over a 20 day trading period returns averaged -.34%, finishing positive also 67% of the time, and the worst return was a drop of -4.48%. All-in-all momomentum is elevated, therefore it is only normal for markets to consolidate, and the historical numbers suggest this may be the case.
