Pulling back 13% this week, Tristel's LON:TSTL) five-year decline in earnings may be coming into investors focus

It's been a soft week for Tristel plc (LON:TSTL) shares, which are down 13%. Looking further back, the stock has generated good profits over five years. Its return of 31% has certainly bested the market return! Unfortunately not all shareholders will have held it for the long term, so spare a thought for those caught in the 20% decline over the last twelve months.

Since the long term performance has been good but there's been a recent pullback of 13%, let's check if the fundamentals match the share price.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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.

Tristel's earnings per share are down 25% per year, despite strong share price performance over five years.

This means it's unlikely the market is judging the company based on earnings growth. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

We doubt the modest 1.9% dividend yield is attracting many buyers to the stock. In contrast revenue growth of 9.4% per year is probably viewed as evidence that Tristel is growing, a real positive. It's quite possible that management are prioritizing revenue growth over EPS growth at the moment.

We consider it positive that insiders have made significant purchases in the last year. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

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 Tristel the TSR over the last 5 years was 43%, 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

While the broader market lost about 3.5% in the twelve months, Tristel shareholders did even worse, losing 18% (even including dividends). 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. Longer term investors wouldn't be so upset, since they would have made 7%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
