Mutual Fund
Regulated retail investment fund offering investors broadly diversified equity portfolios.
A mutual fund is a classic retail fund that pools investor capital and invests it under a defined strategy. Unlike hedge funds, it is heavily regulated (in the US by the Investment Company Act of 1940), can only use leverage and shorts in limited ways and discloses its holdings regularly.
Mutual funds must also file 13F reports once they cross the $100 million threshold — but they additionally publish N-PORT and N-CSR reports that are even more granular.
