Ideally, your overall portfolio should beat the market average. But every investor is virtually certain to have both over-performing and under-performing stocks. So we wouldn’t blame long term RATIONAL Aktiengesellschaft (ETR:RAA) shareholders for doubting their decision to hold, with the stock down 20% over a half decade.
Given the past week has been tough on shareholders, let’s investigate the fundamentals and see what we can learn.
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 way to examine how market sentiment has changed over time is to look at the interaction between a company’s share price and its earnings per share (EPS).
During the unfortunate half decade during which the share price slipped, RATIONAL actually saw its earnings per share (EPS) improve by 22% per year. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Alternatively, growth expectations may have been unreasonable in the past.
It is unusual to see such modest share price growth in the face of sustained EPS improvements. We can look to other metrics to try to understand the situation better.
Revenue is actually up 13% over the time period. A more detailed examination of the revenue and earnings may or may not explain why the share price languishes; there could be an opportunity.

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. In the case of RATIONAL, it has a TSR of -14% for the last 5 years. That exceeds its share price return that we previously mentioned. And there’s no prize for guessing that the dividend payments largely explain the divergence!
RATIONAL shareholders are down 19% for the year (even including dividends), but the market itself is up 17%. 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.
