Statistically speaking, long term investing is a profitable endeavour. But no-one is immune from buying too high. For example, after five long years the The Gym Group plc (LON:GYM) share price is a whole 67% lower. That's not a lot of fun for true believers. The falls have accelerated recently, with the share price down 10% in the last three months.

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

Given that Gym Group didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

Over five years, Gym Group grew its revenue at 6.8% per year. That's a pretty good rate for a long time period. The share price return isn't so respectable with an annual loss of 11% over the period. It seems probably that the business has failed to live up to initial expectations. That could lead to an opportunity if the company is going to become profitable sooner rather than later.

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. This free report showing analyst forecasts should help you form a view on Gym Group

A Different Perspective

It's good to see that Gym Group has rewarded shareholders with a total shareholder return of 3.8% in the last twelve months. That certainly beats the loss of about 11% per year over the last half decade. We generally put more weight on the long term performance over the short term, but the recent improvement could hint at a (positive) inflection point within the business.
