The Passive Bid Explained: How Markets Move Now w/ Michael Green

Summary

Michael Green explains his 'passive bid' thesis, arguing that 401(k) defaults and passive index flows mechanically bid up market-cap-weighted securities and distort price discovery. He describes how active management has shrunk to roughly 7% of trading, making markets more rigid and flow-driven. He also discusses his viral poverty-line work, child care costs, and the 'valley of death' created by benefit phaseouts. Finally, he warns that a passive-driven break in the S&P 500 is a systemic risk and mentions his Simplify high yield fund as a protection-oriented income vehicle.
