The U.S. Securities and Exchange Commission (SEC) has voted 3-2 to approve new rule changes requiring mutual funds and exchange-traded funds (ETFs) to report their portfolio holdings on a monthly basis, instead of the previous quarterly schedule. This decision aims to enhance transparency for investors by providing more timely information about fund holdings. The rule changes are expected to impact how funds disclose their investments, offering investors a clearer view of fund activities. SEC Chairman Gary Gensler expressed support for the amendments, highlighting their importance in delivering timely data to the Commission and investors.
