According to @StockMKTNewz, only about 21% of American families own individual stocks directly, which aligns with the Federal Reserve’s 2022 Survey of Consumer Finances showing 21% direct stock ownership and most equity exposure via mutual funds and retirement accounts (Federal Reserve, Survey of Consumer Finances 2022). For traders, this concentration in pooled vehicles makes ETF and retirement-plan allocations key sentiment channels, as evidenced by the SCF’s breakdown of pooled-vehicle usage (Federal Reserve, Survey of Consumer Finances 2022). With the U.S. Securities and Exchange Commission approving spot Bitcoin ETFs in January 2024, pooled-vehicle adoption now provides a regulated path for mainstream BTC exposure (U.S. Securities and Exchange Commission, January 2024 spot Bitcoin ETF approvals). Trading takeaway: monitor spot Bitcoin ETF creations/redemptions and broad equity ETF flow data alongside SCF household allocation trends to gauge potential liquidity impacts in BTC and ETH (U.S. Securities and Exchange Commission; Federal Reserve, Survey of Consumer Finances 2022).
