Basler Aktiengesellschaft (ETR:BSL) shareholders should be happy to see the share price up 15% in the last month. But that doesn’t change the fact that the returns over the last three years have been stomach churning. In that time the share price has melted like a snowball in the desert, down 88%. So we’re relieved for long term holders to see a bit of uplift. But the more important question is whether the underlying business can justify a higher price still. We really feel for shareholders in this scenario. It’s a good reminder of the importance of diversification, and it’s worth keeping in mind there’s more to life than money, anyway.

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.

Basler isn’t currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. 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 three years Basler saw its revenue shrink by 6.1% per year. That’s not what investors generally want to see. The share price fall of 23% (per year, over three years) is a stern reminder that money-losing companies are expected to grow revenue. We’re generally averse to companies with declining revenues, but we’re not alone in that. There’s no more than a snowball’s chance in hell that share price will head back to its old highs, in the short term.

While the broader market gained around 10% in the last year, Basler shareholders lost 45%. 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 10% 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. To that end, you should be aware of the 1 warning sign we’ve spotted with Basler .
