The once-rebellious Charles Schwab is all grown up as the discount broker now offers the same traditional brokerage services it shunned over three decades ago. Schwab manages more than $2.5 trillion in assets for nearly 12.5 million individual investors and institutional clients. Traders can access its services via telephone, wireless device, the Internet, and through more than 325 offices in 45 states, plus London and Hong Kong. Besides discount brokerage, the firm offers financial research, advice, and planning; investment management; retirement and employee compensation plans; and about 70 proprietary Schwab and Laudus mutual funds.
