Those who invested in Diploma (LON:DPLM) five years ago are up 144%

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, if you buy shares in a high quality company at the right price, you can gain well over 100%. One great example is Diploma PLC (LON:DPLM) which saw its share price drive 124% higher over five years. It's down 1.7% in the last seven days.

Let's take a look at the underlying fundamentals over the longer term, and see if they've been consistent with shareholders 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 15% a year. So the EPS growth rate is rather close to the annualized share price gain of 18% per year. That suggests that the market sentiment around the company hasn't changed much over that time. 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. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Diploma's TSR for the last 5 years was 144%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

It's nice to see that Diploma shareholders have received a total shareholder return of 20% over the last year. And that does include the dividend. That gain is better than the annual TSR over five years, which is 20%. Therefore it seems like sentiment around the company has been positive lately. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. It's always interesting to track share price performance over the longer term. But to understand Diploma better, we need to consider many other factors. Consider risks, for instance.
