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 Overstock.com, Inc. (NASDAQ:OSTK), who have seen the share price tank a massive 81% over a three year period. That might cause some serious doubts about the merits of the initial decision to buy the stock, to put it mildly. And the ride hasn't got any smoother in recent times over the last year, with the price 44% lower in that time. Furthermore, it's down 52% in about a quarter. That's not much fun for holders. We really hope anyone holding through that price crash has a diversified portfolio. Even when you lose money, you don't have to lose the lesson.

With the stock having lost 7.8% in the past week, it's worth taking a look at business performance and seeing if there's any red flags.

Given that Overstock.com didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. Shareholders of unprofitable companies usually expect strong revenue growth. Some companies are willing to postpone profitability to grow revenue faster, but in that case one does expect good top-line growth.

In the last three years Overstock.com saw its revenue shrink by 8.0% per year. That's not what investors generally want to see. Having said that the 22% annualized share price decline highlights the risk of investing in unprofitable companies. We're generally averse to companies with declining revenues, but we're not alone in that. There's no more than a snowball's chance in hell that share price will head back to its old highs, in the short term.

We consider it positive that insiders have made significant purchases in the last year. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business. This free report showing analyst forecasts should help you form a view on Overstock.com

A Different Perspective

Overstock.com shareholders are down 44% for the year, but the market itself is up 11%. 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 8% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. 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. Take risks, for example - Overstock.com has 3 warning signs we think you should be aware of.
