Summary
By the retirement & income deskMike Green joins Excess Returns to discuss how passive investing and fund flows shape stock prices, market concentration and portfolio construction. He connects retirement contributions, target-date funds and index construction to demand for the largest companies, and discusses IPO demand, liquidity versus market capitalization, and factor behavior. He also outlines the framework he is building at Tier1 Alpha: tracking thousands of funds, estimating their impact on individual securities, making small portfolio tilts and incorporating managed futures.
