More than 250 ETFs trade commission-free at Schwab. The list covers all major asset classes and many industry sector funds. All Schwab-brand ETFs make the list, naturally, including Schwab US Dividend Equity (SCHD), a member of the Kiplinger ETF 20, the list of our favorite ETFs. Others hail from SPDR, Invesco and WisdomTree. Schwab also offers 11 of its index mutual funds with no minimum initial investment and no transaction fee, as well as its suite of index-based target-date portfolios. Some of the funds charge annual fees that are as low as Schwab’s ETFs. Schwab S&P 500 Index fund (SWPPX), for instance, costs 0.03% per year. That’s cheaper than the Admiral share class of the Vanguard 500 Index fund, which requires $10,000 to start an account and charges 0.04% in annual expenses.
