Where can I find accurate historical distribution data for mutual funds?
If you want to go far upstream, you can get mutual fund NAV and dividend data from the Nasdaq Mutual Fund Quotation Service (MFQS). This isn't for end-users but rather is offered as a part of the regulatory framework. Not surprisingly, there is a fee for data access. From Nasdaq's MFQS specifications page: To promote market transparency, Nasdaq operates the Mutual Fund Quotation Service (MFQS). MFQS is designed to facilitate the collection and dissemination of daily price, dividends and capital distributions data for mutual funds, money market funds, unit investment trusts (UITs), annuities and structured products.
