As an investor, mistakes are inevitable. But really big losses can really drag down an overall portfolio. So take a moment to sympathize with the long term shareholders of Shutterstock, Inc. (NYSE:SSTK), who have seen the share price tank a massive 74% over a three year period. That'd be enough to cause even the strongest minds some disquiet. The more recent news is of little comfort, with the share price down 36% in a year. Furthermore, it's down 17% in about a quarter. That's not much fun for holders.

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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 4% over the last half decade.
