Charles Schwab has entered the ETF market with a line-up of four commission free ETFs and plans to launch four more by year end.

The first four ETFs include:

• Schwab U.S. Broad Market ETF (SCHB)

• Schwab U.S. Large-Cap ETF (SCHX)

• Schwab U.S. Small-Cap ETF (SCHA)

• Schwab International Equity ETF (SCHF)
