One simple way to benefit from the stock market is to buy an index fund. But if you pick the right individual stocks, you could make more than that. For example, the Thermon Group Holdings, Inc. (NYSE:THR) share price is up 89% in the last three years, clearly besting the market return of around 18% (not including dividends). On the other hand, the returns haven't been quite so good recently, with shareholders up just 8.7%.

On the back of a solid 7-day performance, let's check what role the company's fundamentals have played in driving long term shareholder returns.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Thermon Group Holdings was able to grow its EPS at 94% per year over three years, sending the share price higher. The average annual share price increase of 24% 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

Thermon Group Holdings provided a TSR of 8.7% over the last twelve months. Unfortunately this falls short of the market return. The silver lining is that the gain was actually better than the average annual return of 6% per year over five year. This could indicate that the company is winning over new investors, as it pursues its strategy. If you want to research this stock further, the data on insider buying is an obvious place to start.
