New high explosion
A euphoric reaction to a terrible jobs report pushed 32% of S&P 500 stocks to fresh 52-week highs, one of the highest readings in more than 20 years. According to the Backtest Engine, there have been 7 days with 31.5% or more stocks hitting 52-week highs on the same day. All 7 of them saw the S&P trade lower over the next month, averaging a return of -4.9%. That was typically the worst time frame, and most of them then traded higher afterward. The dates were 2010-04-23, 2010-04-26, 2013-05-14, 2013-05-15, 2013-05-20, 2018-01-12, and 2018-01-16.
