TD Ameritrade offers several investment products – from index mutual and exchange traded funds (ETFs), stocks and options, to more than 300 commission-free ETFs and mutual funds that are top rated by Morningstar. Like others in their league, the firm's index funds follow some of the major markets. The firm's site offers an ETF screener that allows investors to search by fund type or Morningstar rating – similar to others we’ve reviewed such as Fidelity and Charles Schwab. What’s particularly nice about this feature is that investors can specifically search just ETF index funds with a green tag symbol next to the name of each fund to signal it is commission-free. This feature also gives clients easy access to the fund’s prospectus. Similarly, the company offers a mutual fund screener that offers the same features. Another aspect we liked about TD’s fund search is investors have an option to select and search socially responsible funds.

TD Ameritrade has a strong financial outlook. Since opening in 1975, the company has grown to service more than 11 million client accounts and has $1.3 trillion in client assets.
