Investors in Tourmaline Oil (TSE:TOU) have seen incredible returns of 381% over the past five years

Tourmaline Oil Corp. (TSE:TOU) shareholders might be concerned after seeing the share price drop 12% in the last quarter. But that scarcely detracts from the really solid long term returns generated by the company over five years. Indeed, the share price is up an impressive 243% in that time. We think it's more important to dwell on the long term returns than the short term returns. Ultimately business performance will determine whether the stock price continues the positive long term trend.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

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 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).

Over half a decade, Tourmaline Oil managed to grow its earnings per share at 30% a year. So the EPS growth rate is rather close to the annualized share price gain of 28% per year. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. Indeed, it would appear the share price is reacting to the EPS.

It's good to see that there was some significant insider buying in the last three months. That's a positive. That said, we think earnings and revenue growth trends are even more important factors to consider.

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. As it happens, Tourmaline Oil's TSR for the last 5 years was 381%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

While the broader market gained around 14% in the last year, Tourmaline Oil shareholders lost 6.6% (even including dividends). However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 37% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
