It might seem bad, but the worst that can happen when you buy a stock (without leverage) is that its share price goes to zero. But if you buy shares in a really great company, you can more than double your money. For instance the STEP Energy Services Ltd. (TSE:STEP) share price is 170% higher than it was three years ago. Most would be happy with that. And in the last week the share price has popped 5.0%. But this might be partly because the broader market had a good week last week, gaining 2.7%.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

A Different Perspective

Investors in STEP Energy Services had a tough year, with a total loss of 10%, against a market gain of about 20%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 20%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
