Stealth socialism

“Passive” investment vehicles, like those low-fee index funds, now soak up enormous amounts of cash. In America, since 2008, about $600 billion in holdings of actively managed mutual funds (which pick investments strategically) have been sold off, while $1 trillion has flowed into passive funds. So the passive funds now hold gargantuan ownership stakes in large, public firms. That makes for some awkward economics. Research by Jan Fichtner, Eelke Heemskerk and Javier Garcia-Bernardo from the University of Amsterdam tracks the holdings of the “Big Three” asset managers: BlackRock, Vanguard and State Street. Treated as a single entity, they would now be the largest shareholder in just over 40% of listed American firms, which, adjusting for market capitalisation, account for nearly 80% of the market (see chart).
