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. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During five years of share price growth, Union OptechLtd actually saw its EPS drop 5.8% per year.

This means it's unlikely the market is judging the company based on earnings growth. Because earnings per share don't seem to match up with the share price, we'll take a look at other metrics instead.

The modest 0.5% dividend yield is unlikely to be propping up the share price. In contrast revenue growth of 8.5% per year is probably viewed as evidence that Union OptechLtd is growing, a real positive. It's quite possible that management are prioritizing revenue growth over EPS growth at the moment.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, Union OptechLtd's TSR for the last 5 years was 56%, 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 Union OptechLtd shareholders have received a total shareholder return of 50% over the last year. Of course, that includes the dividend. That gain is better than the annual TSR over five years, which is 9%. Therefore it seems like sentiment around the company has been positive lately. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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. Consider for instance, the ever-present spectre of investment risk.
