ElringKlinger (ETR:ZIL2) adds €48m to market cap in the past 7 days, though investors from three years ago are still down 60%

ElringKlinger AG (ETR:ZIL2) shareholders should be happy to see the share price up 16% in the last week. But over the last three years we've seen a quite serious decline. Tragically, the share price declined 61% in that time. So it is really good to see an improvement. After all, could be that the fall was overdone.

While the stock has risen 16% in the past week but long term shareholders are still in the red, let's see what the fundamentals can tell us.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

ElringKlinger became profitable within the last five years. We would usually expect to see the share price rise as a result. So it's worth looking at other metrics to try to understand the share price move.

We note that, in three years, revenue has actually grown at a 8.7% annual rate, so that doesn't seem to be a reason to sell shares. This analysis is just perfunctory, but it might be worth researching ElringKlinger more closely, as sometimes stocks fall unfairly. This could present an opportunity.

A Different Perspective

ElringKlinger shareholders are down 32% for the year (even including dividends), but the market itself is up 1.4%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 2% 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.
