Using RSI to predict a top can be tricky. Current reading of 70 on my excel going back to august 1992 (and have weekly since 1986) has been a top numerous times.
Then again, the donald will make America Great, so who can accuratly predict with that about to happen?
By the way, the market topped out in jan just before the took office both when Reagan was elected and when George W was elected (his was the end of the month actually, after the first major top in march 2000 and another at the end of august, but the market came close again the end of jan 2001, a very bad time to buy. I watched wall st week that time, and all the guests were very bullish, just before a major bear market began. They all loved tech stocks.)
