TD Ameritrade's new ETF Market Center is offering a list of 100 commission-free ETFs for retail investors and independent RIAs interested in long-term investing.

Morningstar Associates LLC, a registered investment advisor (RIA) and unit of Morningstar, compiled the list.

"We worked with independent experts to create an objective list of ETFs focused on long-term investing. Morningstar Associates considered all ETF providers, and neither TD Ameritrade nor Morningstar Associates will receive any incentive from those firms, for inclusion on the list," said Fred Tomczyk, president and chief executive officer of TD Ameritrade.

TD Ameritrade's ETF Market Center also includes an ETF  screener, ETF data and independent research and commentary from Morningstar Inc. to help investors learn more about ETFs, determine  whether ETFs fit their needs and create well-diversified, long-term portfolios. For more information, visit
