Investors in MKS Instruments (NASDAQ:MKSI) have seen respectable returns of 78% over the past five years

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 MKS Instruments, Inc. (NASDAQ:MKSI) has fallen short of that second goal, with a share price rise of 71% over five years, which is below the market return. Some buyers are laughing, though, with an increase of 22% 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.

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.

MKS Instruments' earnings per share are down 52% per year, despite strong share price performance over five years. The impact of extraordinary items on earnings, in the last year, partially explain the diversion.

This means it's unlikely the market is judging the company based on earnings growth. Because earnings per share don't seem to match up with the share price, we'll take a look at other metrics instead.

The modest 0.7% dividend yield is unlikely to be propping up the share price. In contrast revenue growth of 16% per year is probably viewed as evidence that MKS Instruments is growing, a real positive. In that case, the company may be sacrificing current earnings per share to drive growth.

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. As it happens, MKS Instruments' TSR for the last 5 years was 78%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

MKS Instruments provided a TSR of 23% over the year (including dividends). That's fairly close to the broader market return. Most would be happy with a gain, and it helps that the year's return is actually better than the average return over five years, which was 12%. Even if the share price growth slows down from here, there's a good chance that this is business worth watching in the long term. 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.
