Over the last month the CalAmp Corp. (NASDAQ:CAMP) has been much stronger than before, rebounding by 31%. But don't envy holders -- looking back over 5 years the returns have been really bad. In that time the share price has delivered a rude shock to holders, who find themselves down 63% after a long stretch. So is the recent increase sufficient to restore confidence in the stock? Not yet. However, in the best case scenario (far from fait accompli), this improved performance might be sustained.

The recent uptick of 14% could be a positive sign of things to come, so let's take a lot at historical fundamentals.

Check out our latest analysis for CalAmp

Because CalAmp made a loss in the last twelve months, we think the market is probably more focussed on revenue and revenue growth, at least for now. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. Some companies are willing to postpone profitability to grow revenue faster, but in that case one does expect good top-line growth.

Over half a decade CalAmp reduced its trailing twelve month revenue by 4.4% for each year. While far from catastrophic that is not good. The share price decline of 10% compound, over five years, is understandable given the company is losing money, and revenue is moving in the wrong direction. We don't think anyone is rushing to buy this stock. Not that many investors like to invest in companies that are losing money and not growing revenue.

The image below shows how earnings and revenue have tracked over time (if you click on the image you can see greater detail).

We like that insiders have been buying shares in the last twelve months. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business. So it makes a lot of sense to check out what analysts think CalAmp will earn in the future (free profit forecasts).

A Different Perspective

While the broader market lost about 10% in the twelve months, CalAmp shareholders did even worse, losing 48%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 10% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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.
