Random great trade day in strategy I noticed (down 4% at morning, up 15% EOD)

Random call-out of a day’s performance I thought was impressive.

Just saw that this one strategy I used to subscribe to, “Stock Dow”, was down something like 4% (don’t remember exactly) at morning:

Then at the end of day the strategy was up 15%! Quite impressive. Not my strategy and no relation to my strategies, other than that I used to subscribe to this strategy.
