The entities holding the largest aggregate share of corporate equities in America are massive institutional asset management giants, most notably passive index fund providers like The Vanguard Group, BlackRock, and State Street Global Advisors. These financial institutions manage trillions of dollars in mutual funds, exchange-traded funds, and retirement accounts on behalf of tens of millions of retail and institutional investors. Consequently, these institutional asset managers routinely appear as the principal controlling or block shareholders across nearly every major publicly traded corporation listed on American stock exchanges.
