In plain terms

When a stock opens with a big jump or drop versus the previous close, that move usually gets partly given back, so you bet on the reversal.

How it works

Overnight gaps (open vs prior close) overshoot on retail and news-driven order imbalance at the open and then partially reverse, the classic gap-fade / overnight-reversal effect. A large up-gap fades down and a large down-gap fades up.

Return vs. buy & hold
