When you buy a stock there is always a possibility that it could drop 100%. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. For example, the Enpro Inc. (NYSE:NPO) share price has soared 201% in the last half decade. Most would be very happy with that. And in the last month, the share price has gained 30%.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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 the last half decade, Enpro became profitable. Sometimes, the start of profitability is a major inflection point that can signal fast earnings growth to come, which in turn justifies very strong share price gains. Since the company was unprofitable five years ago, but not three years ago, it's worth taking a look at the returns in the last three years, too. Indeed, the Enpro share price has gained 76% in three years. Meanwhile, EPS is up 2.3% per year. This EPS growth is lower than the 21% average annual increase in the share price over three years. So it's fair to assume the market has a higher opinion of the business than it did three years ago.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Enpro the TSR over the last 5 years was 220%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

It's good to see that Enpro has rewarded shareholders with a total shareholder return of 46% in the last twelve months. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 26% 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.
