If You Had Bought Arena Pharmaceuticals (NASDAQ:ARNA) Shares Three Years Ago You'd Have Made 283%

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 instance the Arena Pharmaceuticals, Inc. (NASDAQ:ARNA) share price is 283% higher than it was three years ago. That sort of return is as solid as granite. It's also up 29% in about a month. But this could be related to good market conditions -- stocks in its market are up 21% in the last month.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Arena Pharmaceuticals became profitable within the last three years. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

A Different Perspective

We're pleased to report that Arena Pharmaceuticals shareholders have received a total shareholder return of 13% over one year. That's better than the annualised return of 2.1% over half a decade, implying that the company is doing better recently. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too. Take risks, for example - Arena Pharmaceuticals has 3 warning signs (and 1 which is potentially serious) we think you should know about.
