If you buy and hold a stock for many years, you'd hope to be making a profit. But more than that, you probably want to see it rise more than the market average. But TriMas Corporation (NASDAQ:TRS) has fallen short of that second goal, with a share price rise of 49% over five years, which is below the market return. On a brighter note, more newer shareholders are probably rather content with the 49% share price gain over twelve months.

Since the long term performance has been good but there's been a recent pullback of 3.6%, let's check if the fundamentals match the share price.

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. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Over half a decade, TriMas managed to grow its earnings per share at 9.3% a year. So the EPS growth rate is rather close to the annualized share price gain of 8% per year. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. In fact, the share price seems to largely reflect the EPS growth.

We like that insiders have been buying shares in the last twelve months. 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 TriMas the TSR over the last 5 years was 52%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

It's nice to see that TriMas shareholders have received a total shareholder return of 50% over the last year. And that does include the dividend. That gain is better than the annual TSR over five years, which is 9%. Therefore it seems like sentiment around the company has been positive lately. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
