They're the ones who will drive the stock up on a sustained basis. Stocks that make new highs on increased volume tend to move higher. Outstanding stocks usually form a price consolidation pattern, and then go on to make their biggest gains when their price breaks above the pattern on unusually high volume.

The formula also takes into account the stability of earnings growth. You can look at the number as a percentile.
