Revenue Acceleration
Revenue growth > 15%, accelerating, margins expanding.
A company growing 20% after growing 12% is picking up speed. Prices tend to react more to changes in the growth rate than to the rate itself, because accelerating sales push analysts to raise their forecasts. Widening margins on top mean the extra sales are profitable.
Acquisitions, and comparisons against a weak quarter a year ago, can both make growth look like it is accelerating.
