The main point of investing for the long term is to make money. Furthermore, you'd generally like to see the share price rise faster than the market. Unfortunately for shareholders, while the Diamond Hill Investment Group, Inc. (NASDAQ:DHIL) share price is up 16% in the last five years, that's less than the market return. Unfortunately the share price is down 6.2% in the last year.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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).

Over half a decade, Diamond Hill Investment Group managed to grow its earnings per share at 0.9% a year. This EPS growth is lower than the 3% average annual increase in the share price. This suggests that market participants hold the company in higher regard, these days. And that's hardly shocking given the track record of growth.

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?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Diamond Hill Investment Group, it has a TSR of 67% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Diamond Hill Investment Group shareholders are down 2.5% for the year (even including dividends), but the market itself is up 34%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 11%, 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. 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. Even so, be aware that Diamond Hill Investment Group is showing 3 warning signs in our investment analysis , and 1 of those is a bit concerning...
