Unfortunately, investing is risky - companies can and do go bankrupt. On the other hand, if you find a high quality business to buy (at the right price) you can more than double your money! Take, for example Plantronics, Inc. (NYSE:POLY). Its share price is already up an impressive 149% in the last twelve months. In the last week shares have slid back 1.4%. On the other hand, longer term shareholders have had a tougher run, with the stock falling 51% in three years.

Plantronics wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. When a company doesn't make profits, we'd generally expect to see good revenue growth. Some companies are willing to postpone profitability to grow revenue faster, but in that case one does expect good top-line growth.

Over the last twelve months, Plantronics' revenue grew by 2.2%. That's not great considering the company is losing money. So we wouldn't have expected the share price to rise by 149%. The business will need a lot more growth to justify that increase. We're not so sure that revenue growth is driving the market optimism about the stock.

A Different Perspective

We're pleased to report that Plantronics shareholders have received a total shareholder return of 149% over one year. Notably the five-year annualised TSR loss of 3% per year compares very unfavourably with the recent share price performance. The long term loss makes us cautious, but the short term TSR gain certainly hints at a brighter future. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
