The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But when you pick a company that is really flourishing, you can make more than 100%. Long term PTC Inc. (NASDAQ:PTC) shareholders would be well aware of this, since the stock is up 181% in five years.

So let's assess the underlying fundamentals over the last 5 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. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During the five years of share price growth, PTC moved from a loss to profitability. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here. Given that the company made a profit three years ago, but not five years ago, it is worth looking at the share price returns over the last three years, too. We can see that the PTC share price is up 49% in the last three years. During the same period, EPS grew by 6.5% each year. Notably, the EPS growth has been slower than the annualised share price gain of 14% over three years. So it's fair to assume the market has a higher opinion of the business than it did three years ago.

The company's earnings per share (over time) is depicted in the image below (click to see the exact numbers).

A Different Perspective

PTC shareholders gained a total return of 27% during the year. But that return falls short of the market. On the bright side, that's still a gain, and it's actually better than the average return of 23% over half a decade This suggests the company might be improving over time. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. To that end, you should be aware of the 2 warning signs we've spotted with PTC .
