Investors in Calix (NYSE:CALX) have made a massive return of 996% over the past five years

Long term investing can be life changing when you buy and hold the truly great businesses. And highest quality companies can see their share prices grow by huge amounts. Don't believe it? Then look at the Calix, Inc. (NYSE:CALX) share price. It's 996% higher than it was five years ago. If that doesn't get you thinking about long term investing, we don't know what will. It's also good to see the share price up 63% over the last quarter. It really delights us to see such great share price performance for investors.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

Check out our latest analysis for Calix

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 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.

During the last half decade, Calix became profitable. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

The image below shows how EPS has tracked over time (if you click on the image you can see greater detail).

A Different Perspective

It's good to see that Calix has rewarded shareholders with a total shareholder return of 9.5% in the last twelve months. Having said that, the five-year TSR of 61% a year, is even better. The pessimistic view would be that be that the stock has its best days behind it, but on the other hand the price might simply be moderating while the business itself continues to execute. 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. Consider for instance, the ever-present spectre of investment risk. We've identified 3 warning signs with Calix (at least 1 which is a bit concerning) , and understanding them should be part of your investment process.
