If you love investing in stocks you're bound to buy some losers. But long term Shutterstock, Inc. (NYSE:SSTK) shareholders have had a particularly rough ride in the last three year. Unfortunately, they have held through a 71% decline in the share price in that time. More recently, the share price has dropped a further 8.6% in a month.

With the stock having lost 6.3% in the past week, it's worth taking a look at business performance and seeing if there's any red flags.

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. 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 three years that the share price fell, Shutterstock's earnings per share (EPS) dropped by 23% each year. This reduction in EPS is slower than the 34% annual reduction in the share price. So it's likely that the EPS decline has disappointed the market, leaving investors hesitant to buy.

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. Before buying or selling a stock, we always recommend a close examination of historic growth trends, available here..

A Different Perspective

While the broader market gained around 36% in the last year, Shutterstock shareholders lost 10% (even including dividends). Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 0.6% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
