Ackman is always sent out in front of cameras to give heads-up and what he’s said in the past has a 100% return within those parameters. He’s calling for govt bailouts for not only SVB but others. If there are bank failures in The Plan, Ackman will make sure everyone panics.
Don’t see any ‘panic’ today but history shows this manifests itself, literally, overnight and usually over a weekend or holiday.
I am NOT suggesting you close your bank account but DO keep extra cash on hand because even big banks might limit withdrawals.
