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 Peter Lynch said in One Up On Wall Street, 'Long shots almost never pay off.'

In contrast to all that, I prefer to spend time on companies like Natural Grocers by Vitamin Cottage (NYSE:NGVC), which has not only revenues, but also profits. Even if the shares are fully valued today, most capitalists would recognize its profits as the demonstration of steady value generation. Conversely, a loss-making company is yet to prove itself with profit, and eventually the sweet milk of external capital may run sour.

How Quickly Is Natural Grocers by Vitamin Cottage Increasing Earnings Per Share?

If you believe that markets are even vaguely efficient, then over the long term you'd expect a company's share price to follow its earnings per share (EPS). That makes EPS growth an attractive quality for any company. I, for one, am blown away by the fact that Natural Grocers by Vitamin Cottage has grown EPS by 39% per year, over the last three years. That sort of growth never lasts long, but like a shooting star it is well worth watching when it happens.

I like to see top-line growth as an indication that growth is sustainable, and I look for a high earnings before interest and taxation (EBIT) margin to point to a competitive moat (though some companies with low margins also have moats). Natural Grocers by Vitamin Cottage maintained stable EBIT margins over the last year, all while growing revenue 2.5% to US$1.1b. That's a real positive.
