Diploma's (LON:DPLM) investors will be pleased with their impressive 295% return over the last five years

The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on the bright side, you can make far more than 100% on a really good stock. One great example is Diploma PLC (LON:DPLM) which saw its share price drive 261% higher over five years.

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

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.

Over half a decade, Diploma managed to grow its earnings per share at 5.4% a year. This EPS growth is lower than the 29% average annual increase in the share price. So it's fair to assume the market has a higher opinion of the business than it did five years ago. That's not necessarily surprising considering the five-year track record of earnings growth. This optimism is visible in its fairly high P/E ratio of 78.96.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Diploma the TSR over the last 5 years was 295%, 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

We're pleased to report that Diploma shareholders have received a total shareholder return of 79% over one year. That's including the dividend. That gain is better than the annual TSR over five years, which is 32%. Therefore it seems like sentiment around the company has been positive lately. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
