Grammer (ETR:GMM) investors are sitting on a loss of 64% if they invested five years ago

Generally speaking long term investing is the way to go. But that doesn’t mean long term investors can avoid big losses. Zooming in on an example, the Grammer AG (ETR:GMM) share price dropped 64% in the last half decade. We certainly feel for shareholders who bought near the top. And it’s not just long term holders hurting, because the stock is down 27% in the last year.

So let’s have a look and see if the longer term performance of the company has been in line with the underlying business’ progress.

Grammer wasn’t profitable in the last twelve months, it is unlikely we’ll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. Shareholders of unprofitable companies usually desire strong revenue growth. That’s because it’s hard to be confident a company will be sustainable if revenue growth is negligible, and it never makes a profit.

Over five years, Grammer grew its revenue at 3.1% per year. That’s far from impressive given all the money it is losing. It’s likely this weak growth has contributed to an annualised return of 10% for the last five years. We want to see an acceleration of revenue growth (or profits) before showing much interest in this one. When a stock falls hard like this, some investors like to add the company to a watchlist (in case the business recovers, longer term).

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 10% over the last half decade. 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.
