Siltronic (ETR:WAF) sheds €116m, company earnings and investor returns have been trending downwards for past three years

If you love investing in stocks you're bound to buy some losers. But long term Siltronic AG (ETR:WAF) shareholders have had a particularly rough ride in the last three year. Sadly for them, the share price is down 67% in that time. The more recent news is of little comfort, with the share price down 48% in a year. The falls have accelerated recently, with the share price down 31% in the last three months.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

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 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.

Siltronic saw its EPS decline at a compound rate of 22% per year, over the last three years. The share price decline of 31% is actually steeper than the EPS slippage. So it's likely that the EPS decline has disappointed the market, leaving investors hesitant to buy.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. We note that for Siltronic the TSR over the last 3 years was -64%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

While the broader market gained around 10% in the last year, Siltronic shareholders lost 47% (even including dividends). 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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 7% per year over five years. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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. To that end, you should learn about the 4 warning signs we've spotted with Siltronic (including 2 which shouldn't be ignored) .
