Grammer (ETR:GMM) adds €25m to market cap in the past 7 days, though investors from five years ago are still down 75%

Grammer AG (ETR:GMM) shareholders will doubtless be very grateful to see the share price up 47% in the last month. But that doesn't change the fact that the returns over the last half decade have been stomach churning. In fact, the share price has tumbled down a mountain to land 76% lower after that period. The recent bounce might mean the long decline is over, but we are not confident. The important question is if the business itself justifies a higher share price in the long term.

While the stock has risen 29% in the past week but long term shareholders are still in the red, let's see what the fundamentals can tell us.

Because Grammer made a loss in the last twelve months, we think the market is probably more focussed on revenue and revenue growth, at least for now. When a company doesn't make profits, we'd generally hope to see good 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.

In the last half decade, Grammer saw its revenue increase by 4.8% per year. That's not a very high growth rate considering it doesn't make profits. It's not so sure that share price crash of 12% per year is completely deserved, but the market is doubtless disappointed. While we're definitely wary of the stock, after that kind of performance, it could be an over-reaction. A company like this generally needs to produce profits before it can find favour with new investors.

A Different Perspective

Investors in Grammer had a tough year, with a total loss of 34%, against a market gain of about 17%. 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 12% 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. 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.
