It's not possible to invest over long periods without making some bad investments. But really big losses can really drag down an overall portfolio. So consider, for a moment, the misfortune of Forrester Research, Inc. (NASDAQ:FORR) investors who have held the stock for three years as it declined a whopping 73%. That would be a disturbing experience. The more recent news is of little comfort, with the share price down 36% in a year. Shareholders have had an even rougher run lately, with the share price down 11% in the last 90 days. We note that the company has reported results fairly recently; and the market is hardly delighted. You can check out the latest numbers in our company report.

Since shareholders are down over the longer term, lets look at the underlying fundamentals over the that time and see if they've been consistent with returns.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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.

Forrester Research saw its share price decline over the three years in which its EPS also dropped, falling to a loss. This was, in part, due to extraordinary items impacting earnings. Due to the loss, it's not easy to use EPS as a reliable guide to the business. However, we can say we'd expect to see a falling share price in this scenario.

A Different Perspective

Investors in Forrester Research had a tough year, with a total loss of 36%, against a market gain of about 32%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 10% per year over five years. 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.
