Innospec (NASDAQ:IOSP) shareholders have earned a 9.8% CAGR over the last five years

The main point of investing for the long term is to make money. But more than that, you probably want to see it rise more than the market average. But Innospec Inc. (NASDAQ:IOSP) has fallen short of that second goal, with a share price rise of 50% over five years, which is below the market return. However, more recent buyers should be happy with the increase of 23% over the last year.

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

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, Innospec achieved compound earnings per share (EPS) growth of 9.9% per year. So the EPS growth rate is rather close to the annualized share price gain of 8% per year. That suggests that the market sentiment around the company hasn't changed much over that time. In fact, the share price seems to largely reflect the EPS growth.

We like that insiders have been buying shares in the last twelve months. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Innospec the TSR over the last 5 years was 59%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Innospec shareholders have received returns of 24% over twelve months (even including dividends), which isn't far from the general 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 10%. It is possible that management foresight will bring growth well into the future, even if the share price slows down. 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.
