Watch CNBC's Bob Pisani interview Charles Schwab on "The Halftime Report."
Schwab is the founder and chairman of brokerage firm giant Charles Schwab, which holds about $3.72 trillion in client assets.
As of Monday, Charles Schwab is no longer charging commission fees for U.S. stocks, ETFs and options trades. Brokerage rivals E-Trade, Interactive Brokers and TD Ameritrade all dropped their commission fees in the last two weeks in the latest move of the brokerage fee wars.
