I say the Fed has already placed a soft put under the market (thats why we closed still above -20% from ATH this week) and they will immediately turn it into a hard put if necessary. They want a deflation of the vubble, not a crash. Burry still lives in the world pre 2008 where the Fed doesen't step in if the bubble bursts.
The problem is not Fed doesn’t come to the rescue, but it has much less effective tools now at its disposal with inflation running high.
