In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But in any portfolio, there are likely to be some stocks that fall short of that benchmark. Unfortunately, that's been the case for longer term Diana Shipping Inc. (NYSE:DSX) shareholders, since the share price is down 56% in the last three years, falling well short of the market return of around 33%. And over the last year the share price fell 37%, so we doubt many shareholders are delighted. Furthermore, it's down 20% in about a quarter. That's not much fun for holders.

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

Check out our latest analysis for Diana Shipping

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 imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Although the share price is down over three years, Diana Shipping actually managed to grow EPS by 15% per year in that time. This is quite a puzzle, and suggests there might be something temporarily buoying the share price. Or else the company was over-hyped in the past, and so its growth has disappointed.

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.

We note that the dividend seems healthy enough, so that probably doesn't explain the share price drop. We like that Diana Shipping has actually grown 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?

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 Diana Shipping, it has a TSR of -30% 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

Investors in Diana Shipping had a tough year, with a total loss of 32% (including dividends), against a market gain of about 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 3% 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. It's always interesting to track share price performance over the longer term. But to understand Diana Shipping better, we need to consider many other factors. Consider for instance, the ever-present spectre of investment risk.
