Interesting fact is that if the stock market rallies over 50% from bottom, the bottom is in and bear market is over (we have rallied 50% right now so need to see if we can get over 50%). This has happened 20 of 20 times in the past. This data is from legendary trader Larry Williams who on March 17 became bullish and called the market bottom. He does not think we will see another low based on all his technical indicators.

I have noticed one time quite recently when the above wasn't true (although depends whether he's counting drops of less than 20%). As in 2015 it regained almost the entire decline before falling lower again. So there might be other periods to that he left out. But certainly the weighting is that it's true more often times than not. 

So will be interesting to see if the S&P 500 does close above the 50% level. But we haven't closed a week above it yet.
