Tnx for the stats! Something else that may be unprecedented is the level of passive/index investing.  Regular 401k deductions, FIRE, pensions, etc., buy and don’t open their monthly statements, creating a slow-drip bid and a lack of sellers. Burry and others have been outlining the bubble potential, but it’s less clear what, if anything, could deflate it (it’s like wondering where the money printing will end).
