It might seem bad, but the worst that can happen when you buy a stock (without leverage) is that its share price goes to zero. But in contrast you can make much more than 100% if the company does well. For example, the Tsakos Energy Navigation Limited (NYSE:TEN) share price has soared 174% in the last three years. How nice for those who held the stock! In more good news, the share price has risen 9.6% in thirty days. But this could be related to good market conditions -- stocks in its market are up 5.8% in the last month.

So let's assess the underlying fundamentals over the last 3 years and see if they've moved in lock-step with shareholder returns.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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).

Tsakos Energy Navigation became profitable within the last three years. 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?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Tsakos Energy Navigation the TSR over the last 3 years was 200%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

Tsakos Energy Navigation provided a TSR of 23% over the last twelve months. 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 9% over half a decade It is possible that returns will improve along with the business fundamentals. 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. Take risks, for example - Tsakos Energy Navigation has 3 warning signs (and 1 which makes us a bit uncomfortable) we think you should know about.
