TD Ameritrade Holding Inc. is a securities brokerage and technology-based financial-services firm. The Omaha, Neb.-based company provides services through a national branch network, relationships with independent registered investment advisers, and the Internet.

The company is the result of Ameritrade and TD Waterhouse joining forces in 2006, which gave Toronto Dominion Bank a nearly 40% stake in the firm, now at 45%. In 2008, TD Bank veteran Fredric J. Tomczyk was named chief executive officer. Joseph H. Moglia vacated that post to succeed founder Joe Ricketts as chairman. Moglia has been an executive at Merrill Lynch's private client division and previously had been defensive coordinator for Dartmouth College's football team.

The changes reflect the online broker's moves to shift its business model to focus on more asset-gathering. With new efforts to boost service and customer satisfaction, the company has made a big push to build its asset management business, which produces fees and is a more consistent source of revenue. TD Ameritrade has repeatedly said it would like to acquire rival E*Trade Financial Corp. The company recently agreed to acquire options broker thinkorswim Group Inc. to push further into the fast-growing options market and build up its investor-education programs. In 2008, the company purchased a portion of Fiserv Inc.'s investment support services business. The company is teaming up with financial-advice guru Suze Orman in a "Save Yourself Retirement Program" to attract new customers and assets.
