Investors in Porvair (LON:PRV) have unfortunately lost 6.6% over the last five years

In This Article:

Ideally, your overall portfolio should beat the market average. But in any portfolio, there will be mixed results between individual stocks. At this point some shareholders may be questioning their investment in Porvair plc (LON:PRV), since the last five years saw the share price fall 11%.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

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.

During the unfortunate half decade during which the share price slipped, Porvair actually saw its earnings per share (EPS) improve by 7.0% per year. So it doesn't seem like EPS is a great guide to understanding how the market is valuing the stock. Alternatively, growth expectations may have been unreasonable in the past.

Generally speaking we'd hope to see stronger share price increases on the back of sustained EPS growth, but other metrics may hold a clue to why the share price performance is relatively modest.

The modest 0.9% dividend yield is unlikely to be guiding the market view of the stock. Revenue is actually up 6.3% over the time period. So it seems one might have to take closer look at the fundamentals to understand why the share price languishes. After all, there may be an opportunity.

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. As it happens, Porvair's TSR for the last 5 years was -6.6%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!
