When you buy a stock there is always a possibility that it could drop 100%. But when you pick a company that is really flourishing, you can make more than 100%. For instance, the price of International Seaways, Inc. (NYSE:INSW) stock is up an impressive 227% over the last five years. It's also good to see the share price up 22% over the last quarter.

The past week has proven to be lucrative for International Seaways investors, so let's see if fundamentals drove the company's five-year performance.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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.

International Seaways' earnings per share are down 0.1% per year, despite strong share price performance over five years.

By glancing at these numbers, we'd posit that the decline in earnings per share is not representative of how the business has changed over the years. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

In fact, the dividend has increased over time, which is a positive. Maybe dividend investors have helped support the share price. The revenue growth of about 21% per year might also encourage buyers.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, International Seaways' TSR for the last 5 years was 418%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's good to see that International Seaways has rewarded shareholders with a total shareholder return of 57% in the last twelve months. Of course, that includes the dividend. That gain is better than the annual TSR over five years, which is 39%. Therefore it seems like sentiment around the company has been positive lately. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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. Like risks, for instance.
