IMI plc (LON:IMI) shareholders have seen the share price descend 16% over the month. But that doesn't change the fact that the returns over the last five years have been very strong. We think most investors would be happy with the 109% return, over that period. To some, the recent pullback wouldn't be surprising after such a fast rise. Only time will tell if there is still too much optimism currently reflected in the share price.

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. 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).

Over half a decade, IMI managed to grow its earnings per share at 12% a year. This EPS growth is slower than the share price growth of 16% per year, over the same period. This suggests that market participants hold the company in higher regard, these days. That's not necessarily surprising considering the five-year track record of earnings growth.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for IMI the TSR over the last 5 years was 134%, 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

IMI shareholders are down 6.1% for the year (even including dividends), but the market itself is up 1.4%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 19%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. It's always interesting to track share price performance over the longer term. But to understand IMI better, we need to consider many other factors.
