The simplest way to invest in stocks is to buy exchange traded funds. But one can do better than that by picking better than average stocks (as part of a diversified portfolio). To wit, the Commvault Systems, Inc. (NASDAQ:CVLT) share price is 48% higher than it was a year ago, much better than the market return of around 21% (not including dividends) in the same period. That's a solid performance by our standards! It is also impressive that the stock is up 33% over three years, adding to the sense that it is a real winner.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

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).

During the last year Commvault Systems saw its earnings per share (EPS) drop below zero. While some may see this as temporary, we're a skeptical bunch, and so we're a little surprised to see the share price go up. It may be that the company has done well on other metrics.

However the year on year revenue growth of 4.1% would help. Many businesses do go through a phase where they have to forgo some profits to drive business development, and sometimes its for the best.

A Different Perspective

It's nice to see that Commvault Systems shareholders have received a total shareholder return of 48% over the last year. That gain is better than the annual TSR over five years, which is 7%. Therefore it seems like sentiment around the company has been positive lately. 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.
