When you buy a stock there is always a possibility that it could drop 100%. But on a lighter note, a good company can see its share price rise well over 100%. One great example is Thermo Fisher Scientific Inc. (NYSE:TMO) which saw its share price drive 118% higher over five years. In the last week shares have slid back 2.0%.

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

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Over half a decade, Thermo Fisher Scientific managed to grow its earnings per share at 15% a year. So the EPS growth rate is rather close to the annualized share price gain of 17% per year. This indicates that investor sentiment towards the company has not changed a great deal. Rather, the share price has approximately tracked EPS 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 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. As it happens, Thermo Fisher Scientific's TSR for the last 5 years was 121%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

Thermo Fisher Scientific provided a TSR of 13% over the last twelve months. But that return falls short of the market. It's probably a good sign that the company has an even better long term track record, having provided shareholders with an annual TSR of 17% over five years. It's quite possible the business continues to execute with prowess, even as the share price gains are slowing. 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. Consider risks, for instance. Every company has them, and we've spotted 1 warning sign for Thermo Fisher Scientific you should know about.
