Further, we believe the company will benefit from the renewed interest of retail investors in the equity market.Further, the company’s association with The Toronto-Dominion Bank TD provides an opportunity to cross sell its products. This is expected to significantly drive organic growth.Amid a volatile operating environment, TD Ameritrade witnessed a continuous rise in organic client assets, which bodes well for the future.
