The number of occurrences is a bit low but certainly suggestive of a downside edge over the next several days. The edge appears the strongest over the 1st 2 days, when much of the damage has been done. Not evident above is that 13 of 14 instances closed lower than the trigger-day close at some point in the next 3 days.
In order to gain a larger sample size I also looked at Nasdaq Spyx readings below 10.
Results here are similar to the 1st test, but with a decent sample size. This all suggests a downside edge in the Nasdaq 100 over the next few days.
