1. Skyrocketing Revenue Shows Strong Momentum

A company’s long-term sales performance is one signal of its overall quality. Any business can put up a good quarter or two, but the best consistently grow over the long haul. Over the last five years, Monolithic Power Systems grew its sales at an incredible 27.9% compounded annual growth rate. Its growth beat the average semiconductor company and shows its offerings resonate with customers. Semiconductors are a cyclical industry, and long-term investors should be prepared for periods of high growth followed by periods of revenue contractions (which can sometimes offer opportune times to buy).

2. Outstanding Long-Term EPS Growth

Analyzing the long-term change in earnings per share (EPS) shows whether a company's incremental sales were profitable – for example, revenue could be inflated through excessive spending on advertising and promotions.
