In plain terms

Stocks where earnings surprises are accelerating quarter-over-quarter while price is trending up show compounding drift.

How it works

Earnings surprise acceleration (this quarter's surprise larger than the prior quarter's) combined with relative price strength produces a compounding signal. The market underreacts to improving fundamental momentum when it is also visible in price.
