A true trend day
Stocks rocketed right from the open and didn't give much back. The NYSE TICK hit a record high, meaning the most-ever stocks trading on an uptick minus those on a downtick. And it never fell below -500 at any point during the day (using Bloomberg data). Of the few other times that buyers were this persistent, the S&P fell back over the next 2-4 weeks each time, but of course, the sample size is tiny. The dates were 2001-01-03, 2001-12-21, 2003-07-02, and 2020-05-08. Relaxing the parameters some saw less of a downside edge over the next couple of weeks, so it was not very robust.
