Quote from belmondo:
porsche didn't trade at these days. it is just stupidity and greed of short sellers. VW was the most sortable stocks in germany. we!ve shorted VW as well but we were awere of the risk and get out soon. others has to pay. i don't see any manipulation.
porsche owns all stock. who wants to short, borrows share from porche and then have to give back to porche. the risk has been known
How do you know Porsche didn't trade?
Anyhow, as I said, it's just my opinion.
