it was not quite as simple as that.
Maybe not, but it wasn't that much more complicated....
porsche owned ~42% of VW and had arranged undisclosed option to buy nearly 32% more to make a total of just over 74%.
Indeed. Just like they said they planned to do quite a while back.
the hedge funds knew porsche was buying shares
I'm not even sure they knew that, given how big a screw-up they made
but did not expect them to be able to buy that much in one go which was largely true as they did have the money to exercise all those options.
Not at that precise moment, no. But they did have a game plan that involved them exercising those options down the line - and as I keep pointing out, they weren't keeping that game plan secret.
then on a sunday after the story had been broken in the FT Porsche admitted the size of their options so the hedge funds which had shorted the shares had in effect sold them to porsche who would not going to sell them again so the hedgefunds had to buy many more shares back than were available to return them to their original owners but they couldnt hence the big spike in price.
porsche then a couple of days later sold some of the shares they had at a very large profit which has allowed them to buy more shares now the price has returned to its true market value.
Yep. Shock as Porsche say they are going to do something, and then do it. Certainly shocked the short-sellers.
it was very clever but may be borderline illegal under market munipulation rules.
Why? Under German law, they were under no obligation to tell folks what they were doing. And yet they did, in 2005.
ultimately by betting the wrong way the hedgefunds have paid for porsche to buy vw.
The thing is, people are making out as if Porsche planned for the short-sellers to obligingly screw the pooch and allow Porsche to buy up all those VW shares. I'm sorry, but there is no way that Porsche said to themselves back in 2005 "I know, lets engineer an absolute panic in September 2008 and make lots of money to fund our takeover of Volkswagen".
The short-sellers ignored the gigantic flashing neon signs that were pointing out just what Porsche were doing. And they've paid the price. They also probably paid for a bloody good Christmas party in Stuttgart!
