They simply told, that they can not produce enough chips for the market and also TSMC can not produce enough. There is a shortage of a product in the market, which will lead to a rise of the chip prices.
Long term profit for infineon, even when they now make not good earnings in this or maybe next quartal.
A good buy entry maybe is the support line about 31 € for an cheaper entry, but patientliy wait! Maybe it also break for a cheaper entry price to take now.
So on watchlist for the next 2 weeks for a good entry.
