If you want to find winning -- or losing -- stock ideas, you'll need to understand what lies beneath a company's reported revenue. Many investors screen on metrics like net income or related measurements such as EBIT, EBITDA, or operating cash flow. But companies know that Wall Street is closely monitoring these factors, and they can sometimes attempt to massage their numbers in hopes of providing a "good story" for investors.
Investors can get a much better picture of a company's revenue or cash flow story by looking into the quality of earnings instead. Diligent Fools will play the role of forensic accountant, reading all of a company's SEC filings and financial statements in search of accounting tricks that might be masking deteriorating performance. To help your investigation, I've uncovered a powerful shortcut: subtracting net income from operating cash flow.
Let's test how well this shortcut works by rounding up a clutch of companies with five-year annualized growth rates greater than 10%. Then we'll rank these contenders with my quality-of -earnings metric, divided by each company's market cap to normalize the candidates' different sizes.
Here are the top two and the bottom two companies in my quality-of-earnings screen:
The highest
|
Company
|
5-Year Revenue Growth
|
|
The Cooper Companies (NYSE: COO )
|
19.34%
|
|
AngioDynamics (Nasdaq: ANGO )
|
32.32%
|

The lowest
|
Company
|
5-Year Revenue Growth
|
|
Natus Medical (Nasdaq: BABY )
|
39.61%
|
|
Stereotaxis (Nasdaq: STXS )
|
26.95%
|
And let's look at how health-care companies have performed over the past decade when ranked by the quality-of-earnings metric. In the following charts, quantile 1 represents stocks with the highest earnings quality, while quantile 5 represents the lowest:
The graphs don't lie
Companies with higher quality of earnings significantly outperform those with lower quality. Stocks in quantile 1 generated more than 30% annualized returns, while the bottom feeders of quantile 5 stocks returned about 7%.
Clearly, the revenue growth story for the health-care equipment and supplies companies above is an inadequate measure to evaluate these companies. Our earnings quality screen (and decade of corroborating evidence!) suggests that The Cooper Companies and AngioDynamics are our buy candidates while Stereotaxis and Natus Medical might be shorting opportunities. Of course, before pulling the trigger, investors should do their homework to get an even better and more comprehensive picture of quality of earnings and earnings growth.
Finding companies to short using a quality of earnings screen will take more than my simple quality-of-earnings shortcut.
