Charles Schwab has lowered its stock and ETF commission from $8.95 to $0, making the broker less expensive than its rivals Merrill Edge and Etrade. Despite the new pricing, Schwab provides all ETF's commission-free. The company also has over 300 brick-and-mortar locations plus 24/7 service over the phone or via on-line chat. Its very good desktop platform StreetSmart Edge only requires a $1,000 account balance, and its mobile app streams CNBC news free of charge.
