The five-year shareholder returns and company earnings persist lower as Bertrandt (ETR:BDT) stock falls a further 11% in past week

In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But every investor is virtually certain to have both over-performing and under-performing stocks. So we wouldn't blame long term Bertrandt Aktiengesellschaft (ETR:BDT) shareholders for doubting their decision to hold, with the stock down 42% over a half decade. And some of the more recent buyers are probably worried, too, with the stock falling 26% in the last year. The falls have accelerated recently, with the share price down 15% in the last three months. We note that the company has reported results fairly recently; and the market is hardly delighted. You can check out the latest numbers in our company report.

If the past week is anything to go by, investor sentiment for Bertrandt isn't positive, so let's see if there's a mismatch between fundamentals and the share price.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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.

Bertrandt became profitable within the last five years. That would generally be considered a positive, so we are surprised to see the share price is down. Other metrics might give us a better handle on how its value is changing over time.

In contrast to the share price, revenue has actually increased by 2.9% a year in the five year period. So it seems one might have to take closer look at the fundamentals to understand why the share price languishes. After all, there may be an opportunity.

It is of course excellent to see how Bertrandt has grown profits over the years, but the future is more important for shareholders. If you are thinking of buying or selling Bertrandt stock, you should check out this FREE detailed report on its balance sheet.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Bertrandt the TSR over the last 5 years was -37%, 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

Bertrandt shareholders are down 24% for the year (even including dividends), but the market itself is up 8.1%. 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 6% per year over five years. 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.
