Apparently Red Hat, a vendor of a commercial linux distribution, has been doing well during the recession. This makes sense intuitively, people are looking for ways to cut costs due to the economic climate, and giving Microsoft less money seams to be a good way to go about it.
This reminds me of a classic interview question people get asked by investment banks, “Can you think of an asset with a negative beta?”
So next time someone gets asked that question they can say something besides “funeral homes” (stocks brokers jump out windows during recessions etc.. the most common answer or so I’m told!) . They can say that open source software vendors might also:)
