The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. For example, the Charles River Laboratories International, Inc. (NYSE:CRL) share price has soared 147% in the last half decade. Most would be very happy with that. On top of that, the share price is up 33% in about a quarter. But this move may well have been assisted by the reasonably buoyant market (up 17% in 90 days).

Check out our latest analysis for Charles River Laboratories International

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Over half a decade, Charles River Laboratories International managed to grow its earnings per share at 13% a year. This EPS growth is slower than the share price growth of 20% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. That's not necessarily surprising considering the five-year track record of earnings growth.

Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity.
