The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But in contrast you can make much more than 100% if the company does well. To wit, the Tsakos Energy Navigation Limited (NYSE:TNP) share price has flown 249% in the last three years. Most would be happy with that. On top of that, the share price is up 18% in about a quarter.

Since the long term performance has been good but there's been a recent pullback of 6.8%, let's check if the fundamentals match the share price.

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. 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 three years of share price growth, Tsakos Energy Navigation 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.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Tsakos Energy Navigation, it has a TSR of 279% for the last 3 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

We're pleased to report that Tsakos Energy Navigation shareholders have received a total shareholder return of 58% over one year. Of course, that includes the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 16% 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. It's always interesting to track share price performance over the longer term. But to understand Tsakos Energy Navigation better, we need to consider many other factors.
