Index funds vis-à-vis active management

Buffett has been a supporter of index funds for people who are either not interested in managing their own money or do not have the time. Buffett is skeptical that active management can outperform the market in the long run, and has advised both individual and institutional investors to move their money to low-cost index funds that track broad, diversified stock market indices. Buffett said in one of his letters to shareholders that "when trillions of dollars are managed by Wall Streeters charging high fees, it will usually be the managers who reap outsized profits, not the clients". In 2007, Buffett made a bet with numerous managers that a simple S&P 500 index fund will outperform hedge funds that charge exorbitant fees. By 2017, the index fund was outperforming every hedge fund that made the bet against Buffett.
