Investing in Thermon Group Holdings (NYSE:THR) three years ago would have delivered you a 129% gain

It might seem bad, but the worst that can happen when you buy a stock (without leverage) is that its share price goes to zero. But if you buy shares in a really great company, you can more than double your money. To wit, the Thermon Group Holdings, Inc. (NYSE:THR) share price has flown 129% in the last three years. That sort of return is as solid as granite.

So let's assess the underlying fundamentals over the last 3 years and see if they've moved in lock-step with shareholder returns.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During three years of share price growth, Thermon Group Holdings achieved compound earnings per share growth of 104% per year. The average annual share price increase of 32% is actually lower than the EPS growth. So one could reasonably conclude that the market has cooled on the stock.

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money.

A Different Perspective

It's nice to see that Thermon Group Holdings shareholders have received a total shareholder return of 67% over the last year. Since the one-year TSR is better than the five-year TSR (the latter coming in at 2% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time.
