For many, the main point of investing is to generate higher returns than the overall market. But every investor is virtually certain to have both over-performing and under-performing stocks. At this point some shareholders may be questioning their investment in CENIT Aktiengesellschaft (ETR:CSH), since the last five years saw the share price fall 20%. Even worse, it's down 13% in about a month, which isn't fun at all.

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.

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 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).

During the five years over which the share price declined, CENIT's earnings per share (EPS) dropped by 1.6% each year. This reduction in EPS is less than the 4% annual reduction in the share price. So it seems the market was too confident about the business, in the past.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, CENIT's TSR for the last 5 years was -6.0%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

While the broader market gained around 15% in the last year, CENIT shareholders lost 1.6% (even including dividends). However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 1.2% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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. Even so, be aware that CENIT is showing 1 warning sign in our investment analysis , you should know about...
