afternoon drift
In plain terms
When a stock pushes hard in the afternoon (when the big institutions trade), it tends to keep moving the same way the next day.
How it works
Afternoon returns are dominated by informed institutional flow, unlike the noisier overnight-reaction morning session, and these time-of-day return components persist. A strong afternoon push tends to continue into the next day's open.

A stock that finishes the day strong (rising into the bell and above its average price) tends to keep rising the next day.
A big rush of buying or selling right into the closing bell tends to keep pushing the price the same way the next day.
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.
