Some STM Group (LON:STM) Shareholders Are Down 45%

STM Group Plc (LON:STM) shareholders should be happy to see the share price up 18% in the last month. But that doesn't help the fact that the three year return is less impressive. In fact, the share price is down 45% in the last three years, falling well short of the market return.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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 three years of share price decline, STM Group actually saw its earnings per share (EPS) improve by 21% per year. This is quite a puzzle, and suggests there might be something temporarily buoying the share price. Or else the company was over-hyped in the past, and so its growth has disappointed.

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 note that the dividend seems healthy enough, so that probably doesn't explain the share price drop. We like that STM Group has actually grown its revenue over the last three years. But it's not clear to us why the share price is down. It might be worth diving deeper into the fundamentals, lest an opportunity goes begging.

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. As it happens, STM Group's TSR for the last 3 years was -38%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

Investors in STM Group had a tough year, with a total loss of 41% (including dividends) , against a market gain of about 11%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 4.2%, 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.
