Many investors define successful investing as beating the market average over the long term. But its virtually certain that sometimes you will buy stocks that fall short of the market average returns. Unfortunately, that's been the case for longer term Astec Industries, Inc. (NASDAQ:ASTE) shareholders, since the share price is down 40% in the last three years, falling well short of the market return of around 22%. And over the last year the share price fell 26%, so we doubt many shareholders are delighted.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

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 flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Over the three years that the share price declined, Astec Industries' earnings per share (EPS) dropped significantly, falling to a loss. Extraordinary items contributed to this situation. Since the company has fallen to a loss making position, it's hard to compare the change in EPS with the share price change. But it's safe to say we'd generally expect the share price to be lower as a result!

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Astec Industries the TSR over the last 3 years was -37%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market gained around 38% in the last year, Astec Industries shareholders lost 25% (even including dividends). 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 1.3%, 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. Consider risks, for instance.
