CalAmp (NASDAQ:CAMP) shareholders have endured a 84% loss from investing in the stock five years ago

Long term investing is the way to go, but that doesn't mean you should hold every stock forever. We don't wish catastrophic capital loss on anyone. Imagine if you held CalAmp Corp. (NASDAQ:CAMP) for half a decade as the share price tanked 84%. And we doubt long term believers are the only worried holders, since the stock price has declined 63% over the last twelve months. Shareholders have had an even rougher run lately, with the share price down 39% in the last 90 days. While a drop like that is definitely a body blow, money isn't as important as health and happiness.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

CalAmp wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

Over half a decade CalAmp reduced its trailing twelve month revenue by 5.6% for each year. While far from catastrophic that is not good. If a business loses money, you want it to grow, so no surprises that the share price has dropped 13% each year in that time. It takes a certain kind of mental fortitude (or recklessness) to buy shares in a company that loses money and doesn't grow revenue. That is not really what the successful investors we know aim for.

We consider it positive that insiders have made significant purchases in the last year. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

A Different Perspective

While the broader market lost about 19% in the twelve months, CalAmp shareholders did even worse, losing 63%. 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 13% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. 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.
