TD Ameritrade on Monday announced a nearly three-fold increase of its commission-free exchange-traded funds trading program, which it says enables it to offer the most commission-free ETFs in the industry, as well as the largest selection of non-proprietary, commission-free ETFs.

Effective on October 17, TD Ameritrade will expand its ETF lineup to 296 funds from 100 for its client base of registered investment advisors and individual investors.

The platform includes ETFs from eight providers: AGFiQ QuantShares; First Trust Portfolios; iShares; J.P. Morgan Asset Management; PowerShares by Invesco; ProShares; State Street Global Advisors and Wisdom Tree.

The lineup of 296 ETFs covers 77 Morningstar categories and provides increased sector and commodity coverage, according to TD Ameritrade. It also includes State Street’s newly announced suite of 15 ultra-low-cost SPDR ETFs.
