The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. For instance, the price of Shelf Drilling, Ltd. (OB:SHLF) stock is up an impressive 220% over the last five years. It's also good to see the share price up 46% over the last quarter.

The past week has proven to be lucrative for Shelf Drilling investors, so let's see if fundamentals drove the company's five-year performance.

A Different Perspective

While the broader market gained around 13% in the last year, Shelf Drilling shareholders lost 60%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 26% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering.
