The past year for Digital Realty Trust (NYSE:DLR) investors has not been profitable

The simplest way to benefit from a rising market is to buy an index fund. Active investors aim to buy stocks that vastly outperform the market - but in the process, they risk under-performance. Investors in Digital Realty Trust, Inc. (NYSE:DLR) have tasted that bitter downside in the last year, as the share price dropped 18%. That's disappointing when you consider the market declined 12%. On the bright side, the stock is actually up 7.6% in the last three years.

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.

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 the unfortunate twelve months during which the Digital Realty Trust share price fell, it actually saw its earnings per share (EPS) improve by 207%. It could be that the share price was previously over-hyped.

It's surprising to see the share price fall so much, despite the improved EPS. But we might find some different metrics explain the share price movements better.

Digital Realty Trust's revenue is actually up 9.1% over the last year. Since the fundamental metrics don't readily explain the share price drop, there might be an opportunity if the market has overreacted.

It's good to see that there was some significant insider buying in the last three months. That's a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business. So we recommend checking out this free report showing consensus forecasts

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 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Digital Realty Trust, it has a TSR of -15% for the last 1 year. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

While the broader market lost about 12% in the twelve months, Digital Realty Trust shareholders did even worse, losing 15% (even including dividends). Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. On the bright side, long term shareholders have made money, with a gain of 7% 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. 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. Consider for instance, the ever-present spectre of investment risk.
