Many investors define successful investing as beating the market average over the long term. But if you try your hand at stock picking, you risk returning less than the market. Unfortunately, that's been the case for longer term Diana Shipping Inc. (NYSE:DSX) shareholders, since the share price is down 52% in the last three years, falling well short of the market return of around 17%. And over the last year the share price fell 32%, so we doubt many shareholders are delighted. Furthermore, it's down 18% in about a quarter. That's not much fun for holders.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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 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.

Diana Shipping became profitable within the last five years. That would generally be considered a positive, so we are surprised to see the share price is down. So given the share price is down it's worth checking some other metrics too.

We note that the dividend seems healthy enough, so that probably doesn't explain the share price drop. It's good to see that Diana Shipping has increased its revenue over the last three years. But it's not clear to us why the share price is down. It might be worth diving deeper into the fundamentals, lest an opportunity goes begging.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for Diana Shipping the TSR over the last 3 years was -16%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Diana Shipping shareholders are down 23% for the year (even including dividends), but the market itself is up 24%. 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 5% 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. 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.
