Passive money is eating stocks and Bitcoin may be next to get a huge liquidity injection

A notable development has hit the crypto markets. Passive investing has become one of the most powerful forces reshaping equity markets, and the evidence is accumulating in the returns data. Bloomberg Intelligence data compiled by ETF analyst James Seyffart shows stocks with rising passive ownership have dramatically outperformed those losing passive ownership over the past three years.

Bitcoin ETFs work through investor demand, with purchases arriving as creation flows and sales clearing through redemptions on a discretionary timeline, independent of any reconstitution schedule or index mandate.

A BlackRock portfolio note from December 2024 described a 1% to 2% Bitcoin allocation as a reasonable range for multi-asset portfolios for investors who accept the risk of rapid price plunges and believe in wider adoption . When the world's largest asset manager frames a volatile asset in allocation-sizing terms, it becomes a line item that advisors can discuss in portfolio construction terms.
