SGL Carbon (ETR:SGL) shareholders have endured a 24% loss from investing in the stock a year ago

In this article:

It's easy to match the overall market return by buying an index fund. Active investors aim to buy stocks that vastly outperform the market - but in the process, they risk under-performance. Investors in SGL Carbon SE (ETR:SGL) have tasted that bitter downside in the last year, as the share price dropped 24%. That falls noticeably short of the market return of around 11%. At least the damage isn't so bad if you look at the last three years, since the stock is down 9.0% in that time.

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.

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.

Unhappily, SGL Carbon had to report a 43% decline in EPS over the last year. This fall in the EPS is significantly worse than the 24% the share price fall. So despite the weak per-share profits, some investors are probably relieved the situation wasn't more difficult.

A Different Perspective

SGL Carbon shareholders are down 24% for the year, but the market itself is up 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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 3% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
