As an investor its worth striving to ensure your overall portfolio beats the market average. But in any portfolio, there are likely to be some stocks that fall short of that benchmark. Unfortunately, that's been the case for longer term Aramark (NYSE:ARMK) shareholders, since the share price is down 26% in the last three years, falling well short of the market return of around 24%.

So let's have a look and see if the longer term performance of the company has been in line with the underlying business' progress.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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).

During five years of share price growth, Aramark moved from a loss to profitability. We would usually expect to see the share price rise as a result. So it's worth looking at other metrics to try to understand the share price move.

The modest 1.3% dividend yield is unlikely to be guiding the market view of the stock. We note that, in three years, revenue has actually grown at a 21% annual rate, so that doesn't seem to be a reason to sell shares. This analysis is just perfunctory, but it might be worth researching Aramark more closely, as sometimes stocks fall unfairly. This could present an opportunity.

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Aramark the TSR over the last 3 years was 6.8%, 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

Aramark shareholders gained a total return of 14% during the year. But that was short of the market average. The silver lining is that the gain was actually better than the average annual return of 9% per year over five year. This suggests the company might be improving over time. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
