ETF Fees

Investors have also benefited from the so-called fee war. The cheapest ETFs, the Schwab U.S. Broad Market ETF (NYSEArca: SCHB) and the Schwab U.S. Large-Cap ETF (NYSEArca: SCHX), come with a 0.04% expense ratio.

The fee war also spilled over onto brokerage platforms. Now, investors are also able to trade a number of commission-free ETFs on a number of online platforms. [Six Popular Commission-Free ETF Trading Platforms]
