Passive investing in an index fund is a good way to ensure your own returns roughly match the overall market. While individual stocks can be big winners, plenty more fail to generate satisfactory returns. For example, the Summit Materials, Inc. (NYSE:SUM) share price is down 48% in the last year. That's well bellow the market return of 12%. Longer term shareholders haven't suffered as badly, since the stock is down a comparatively less painful 22% in three years. Unfortunately the share price momentum is still quite negative, with prices down 14% in thirty days.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Unhappily, Summit Materials had to report a 73% decline in EPS over the last year. This fall in the EPS is significantly worse than the 48% 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. With a P/E ratio of 50.26, it's fair to say the market sees an EPS rebound on the cards.

NYSE:SUM Past and Future Earnings, April 9th 2019

It's good to see that there was some significant insider buying in the last three months. That's a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business.

A Different Perspective

Over the last year, Summit Materials shareholders took a loss of 48%. In contrast the market gained about 12%. Of course the long term matters more than the short term, and even great stocks will sometimes have a poor year. Shareholders have lost 7.8% per year over the last three years, so the share price drop has become steeper, over the last year; a potential symptom of as yet unsolved challenges. We would be wary of buying into a company with unsolved problems, although some investors will buy into struggling stocks if they believe the price is sufficiently attractive. Investors who like to make money usually check up on insider purchases, such as the price paid, and total amount bought.
