TD Ameritrade Institutional has expanded its Model Market Center to include several new providers, more than 200 additional strategies and a new two-tier structure, according to a company release.

The platform has added 24 new model providers and 232 strategies. With the additions, the center will offer 328 investment model strategies from 35 third-party providers.

Since launching in 2017, more than 3,200 RIAs have signed up to use the platform, the release noted.

“Advisors told us they want more choices, so we’ve built out our platform to include more investment strategies from a broader universe of providers, and this latest expansion is only the beginning,” Dani Fava, director of innovation at TD Ameritrade Institutional, said in a prepared statement. “With Model Market Center, RIAs can leverage the strategies of some well-known money managers to help construct portfolios and devote more time to serving clients.”

The center also provides access to third-party tools to help RIAs as they conduct their model research, including an institutional-grade modeling and investment analytics tool from FinMason to help advisors measure potential model risk, the release said.

Advisors can access quantitative data on the models from Informa through its PSN investment manager database. Research reports from model providers also are available from Informa’s WealthIQ system, the release said.
