Some have more dollars than sense, they say, so even companies that have no revenue, no profit, and a record of falling short, can easily find investors. But as Warren Buffett has mused, 'If you've been playing poker for half an hour and you still don't know who the patsy is, you're the patsy.' When they buy such story stocks, investors are all too often the patsy.

In contrast to all that, I prefer to spend time on companies like LGI Homes (NASDAQ:LGIH), which has not only revenues, but also profits. Now, I'm not saying that the stock is necessarily undervalued today; but I can't shake an appreciation for the profitability of the business itself. Conversely, a loss-making company is yet to prove itself with profit, and eventually the sweet milk of external capital may run sour.

LGI Homes's Earnings Per Share Are Growing.

If a company can keep growing earnings per share (EPS) long enough, its share price will eventually follow. That makes EPS growth an attractive quality for any company. As a tree reaches steadily for the sky, LGI Homes's EPS has grown 37% each year, compound, over three years. As a general rule, we'd say that if a company can keep up that sort of growth, shareholders will be smiling.

The good news is that LGI Homes is growing revenues, and EBIT margins improved by 3.6 percentage points to 17%, over the last year. Ticking those two boxes is a good sign of growth, in my book.
