Porsche wants to take control of VW. We've known that for ages, you might well argue. Well, it seems the message was lost in translation.

Hedge funds are the bogeymen of 2008. They've made loads of extremely speculative investments with other people's money, they regularly sell things that they don't have and worry about how to get them afterwards, and they've destroyed the UK banking system by selling shares in it at attractively low prices in the future on the assumption that they'll lose even more of their value and the bosses of these instruments of darkness will be able to retire on the profit.

OK, that was a bit biased, but...

In many countries this practice of short selling has been temporarily banned and the hedge funds have complained vociferously. Many funds were convinced that the share price of VW was going to drop - after all, car sales have plummeted across Europe. It was a no-brainer. Well, there was certainly no brain involved in making the decision, because as one group was selling VW shares at bargain-basement prices, another group - namely Porsche - was picking them up.
