By buying an index fund, investors can approximate the average market return. But if you pick the right individual stocks, you could make more than that. For example, the Trinity Industries, Inc. (NYSE:TRN) share price is up 36% in the last three years, clearly besting the market return of around 29% (not including dividends). On the other hand, the returns haven't been quite so good recently, with shareholders up just 8.5% , including dividends .

Since it's been a strong week for Trinity Industries shareholders, let's have a look at trend of the longer term fundamentals.

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 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).

Trinity Industries was able to grow its EPS at 74% per year over three years, sending the share price higher. The average annual share price increase of 11% is actually lower than the EPS growth. Therefore, it seems the market has moderated its expectations for growth, somewhat.

We consider it positive that insiders have made significant purchases in the last year. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for Trinity Industries the TSR over the last 3 years was 51%, 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

Trinity Industries provided a TSR of 8.5% over the year (including dividends). That's fairly close to the broader market return. That gain looks pretty satisfying, and it is even better than the five-year TSR of 3% per year. It is possible that management foresight will bring growth well into the future, even if the share price slows down. 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.
