AssetMark Inc., which provides investment and consulting services for advisors, is expanding the strategies it makes available to advisors of high-net-worth clients, the firm announced Monday.

AssetMark, based in Concord, Calif., is partnering with Parametric, a global asset management firm in Seattle and an affiliate of Eaton Vance, to customize portfolios for high-net-worth investors. The new strategy, Parametric Custom Portfolios, has more diversification, risk and tax management features than those previously available to AssetMark advisors, AssetMark says.

Natalie Wolfsen, executive vice president and chief commercialization officer for AssetMark, says, “This solution offers lower-cost, passive portfolios, while also delivering customization and tax management that high-net-worth investors require.”
