Mesa Laboratories (NASDAQ:MLAB investor five-year losses grow to 73% as the stock sheds US$58m this past week

We're definitely into long term investing, but some companies are simply bad investments over any time frame. We really hate to see fellow investors lose their hard-earned money. For example, we sympathize with anyone who was caught holding Mesa Laboratories, Inc. (NASDAQ:MLAB) during the five years that saw its share price drop a whopping 73%. And it's not just long term holders hurting, because the stock is down 46% in the last year. The falls have accelerated recently, with the share price down 48% in the last three months. This could be related to the recent financial results - you can catch up on the most recent data by reading our company report.

If the past week is anything to go by, investor sentiment for Mesa Laboratories isn't positive, so let's see if there's a mismatch between fundamentals and the share price.

Mesa Laboratories 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. Some companies are willing to postpone profitability to grow revenue faster, but in that case one would hope for good top-line growth to make up for the lack of earnings.

Over five years, Mesa Laboratories grew its revenue at 13% per year. That's a pretty good rate for a long time period. So it is unexpected to see the stock down 12% per year in the last five years. The truth is that the growth might be below expectations, and investors are probably worried about the continual losses.

A Different Perspective

While the broader market gained around 22% in the last year, Mesa Laboratories shareholders lost 46% (even including dividends). However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 12% per year over five years. 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. Consider risks, for instance.
