It hasn't been the best quarter for Porton Pharma Solutions Ltd. (SZSE:300363) shareholders, since the share price has fallen 13% in that time. But over the last three years the stock has shone bright like a diamond. In fact, the share price has taken off in that time, up 807%. As long term investors the recent fall doesn't detract all that much from the longer term story. The share price action could signify that the business itself is dramatically improved, in that time. It really delights us to see such great share price performance for investors.

In light of the stock dropping 3.9% in the past week, we want to investigate the longer term story, and see if fundamentals have been the driver of the company's positive three-year return.

Check out our latest analysis for Porton Pharma Solutions

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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).

Porton Pharma Solutions was able to grow its EPS at 86% per year over three years, sending the share price higher. In comparison, the 109% per year gain in the share price outpaces the EPS growth. This indicates that the market is feeling more optimistic on the stock, after the last few years of progress. It is quite common to see investors become enamoured with a business, after a few years of solid progress. This favorable sentiment is reflected in its (fairly optimistic) P/E ratio of 49.81.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, Porton Pharma Solutions' TSR for the last 3 years was 815%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We regret to report that Porton Pharma Solutions shareholders are down 18% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 8.0%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. On the bright side, long term shareholders have made money, with a gain of 38% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. It's always interesting to track share price performance over the longer term. But to understand Porton Pharma Solutions better, we need to consider many other factors.
