The simplest way to invest in stocks is to buy exchange traded funds. But you can do a lot better than that by buying good quality businesses for attractive prices. For example, the Exponent, Inc. (NASDAQ:EXPO) share price is up 77% in the last five years, slightly above the market return. In stark contrast, the stock price has actually fallen 12% in the last year.

So let's investigate 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. 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.

During five years of share price growth, Exponent achieved compound earnings per share (EPS) growth of 15% per year. The EPS growth is more impressive than the yearly share price gain of 12% over the same period. Therefore, it seems the market has become relatively pessimistic about the company.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for Exponent the TSR over the last 5 years was 86%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

Investors in Exponent had a tough year, with a total loss of 11% (including dividends), against a market gain of about 22%. 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 13%, 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.
