Statistically speaking, long term investing is a profitable endeavour. But unfortunately, some companies simply don't succeed. To wit, the Grammer AG (ETR:GMM) share price managed to fall 64% over five long years. That is extremely sub-optimal, to say the least. Shareholders have had an even rougher run lately, with the share price down 12% in the last 90 days.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

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 expect strong revenue growth. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

In the last half decade, Grammer saw its revenue increase by 3.5% per year. That's not a very high growth rate considering it doesn't make profits. This lacklustre growth has no doubt fueled the loss of 10% per year, in that time. We'd want to see proof that future revenue growth is likely to be significantly stronger before getting too interested in Grammer. When a stock falls hard like this, some investors like to add the company to a watchlist (in case the business recovers, longer term).

A Different Perspective

It's good to see that Grammer has rewarded shareholders with a total shareholder return of 20% in the last twelve months. There's no doubt those recent returns are much better than the TSR loss of 10% per year over five years. This makes us a little wary, but the business might have turned around its fortunes. 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.
