In plain terms

A stock that finishes the day strong (rising into the bell and above its average price) tends to keep rising the next day.

How it works

The last-half-hour return and the close-vs-VWAP location proxy informed trading into the close (institutions executing on conviction). A strong close (high last-hour return and close above VWAP) reflects informed buying that persists into the next session; a weak close reflects informed selling.
