The main aim of stock picking is to find the market-beating stocks. But even the best stock picker will only win with some selections. At this point some shareholders may be questioning their investment in Tristel plc (LON:TSTL), since the last five years saw the share price fall 24%.

Now let’s have a look at the company’s fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

Trump has pledged to “unleash” American oil and gas and these 15 US stocks have developments that are poised to benefit.

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).

During the unfortunate half decade during which the share price slipped, Tristel actually saw its earnings per share (EPS) improve by 4.2% per year. So it doesn’t seem like EPS is a great guide to understanding how the market is valuing the stock. Or possibly, the market was previously very optimistic, so the stock has disappointed, despite improving EPS.

Based on these numbers, we’d venture that the market may have been over-optimistic about forecast growth, half a decade ago. Having said that, we might get a better idea of what’s going on with the stock by looking at other metrics.

In contrast to the share price, revenue has actually increased by 7.8% a year in the five year period. A more detailed examination of the revenue and earnings may or may not explain why the share price languishes; there could be an opportunity.

It is important to consider the total shareholder return, as well as the share price return, for any given stock. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Tristel’s TSR for the last 5 years was -14%, which exceeds the share price return mentioned earlier. And there’s no prize for guessing that the dividend payments largely explain the divergence!
