Investors can approximate the average market return by buying an index fund. But if you buy individual stocks, you can do both better or worse than that. For example, the Helical plc (LON:HLCL) share price is down 27% in the last year. That's well below the market decline of 3.0%. On the bright side, the stock is actually up 18% in the last three years. It's up 3.4% in the last seven days.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Unfortunately Helical reported an EPS drop of 55% for the last year. This fall in the EPS is significantly worse than the 27% the share price fall. So the market may not be too worried about the EPS figure, at the moment -- or it may have expected earnings to drop faster.

However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Longer term investors wouldn't be so upset, since they would have made 2%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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. Even so, be aware that Helical is showing 4 warning signs in our investment analysis , and 1 of those is significant...
