Investing in Planet Fitness (NYSE:PLNT) five years ago would have delivered you a 26% gain

When you buy and hold a stock for the long term, you definitely want it to provide a positive return. But more than that, you probably want to see it rise more than the market average. Unfortunately for shareholders, while the Planet Fitness, Inc. (NYSE:PLNT) share price is up 26% in the last five years, that's less than the market return. Zooming in, the stock is actually down 12% in the last year.

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

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.

Over half a decade, Planet Fitness managed to grow its earnings per share at 19% a year. The EPS growth is more impressive than the yearly share price gain of 5% over the same period. So one could conclude that the broader market has become more cautious towards the stock.

A Different Perspective

Investors in Planet Fitness had a tough year, with a total loss of 12%, against a market gain of about 20%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 5% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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. For instance, we've identified 3 warning signs for Planet Fitness (2 are a bit unpleasant) that you should be aware of.
