Omnicom Group's (NYSE:OMC) investors will be pleased with their decent 55% return over the last five years

It hasn't been the best quarter for Omnicom Group Inc. (NYSE:OMC) shareholders, since the share price has fallen 12% in that time. But at least the stock is up over the last five years. However we are not very impressed because the share price is only up 30%, less than the market return of 100%. While the long term returns are impressive, we do have some sympathy for those who bought more recently, given the 20% drop, in the last year.

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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, Omnicom Group managed to grow its earnings per share at 4.0% a year. This EPS growth is lower than the 5% average annual increase in the share price. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth.

Before buying or selling a stock, we always recommend a close examination of historic growth trends, available here.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Omnicom Group, it has a TSR of 55% 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

While the broader market gained around 13% in the last year, Omnicom Group shareholders lost 18% (even including dividends). 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 9%, 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.
