Vestmark, Inc., which provides wealth management software and services, has unveiled an outsourced portfolio management service focused on personalization and scale called VAST.

The offering is a direct indexing service, an investment strategy that involves purchasing the components of an index directly rather than through a mutual fund or exchange-traded fund.

VAST allows advisors to tailor portfolios to each clients’ investment preferences and tax circumstances. It offers active tax overlay across the entire portfolio by including indices, separately managed account managers, exchange-traded funds and other securities in a single tax-managed offering.

VAST also includes a tax transition proposal component, allowing for the tax-efficient transition of money in motion, regardless of whether assets are moving across firms, advisors or from a legacy offering to a tax-managed offering at the same firm, Vestmark said.

“VAST represents a major shift in how client investment and tax preferences can be integrated across an entire portfolio,” said CEO Karl Roessner.

Based in Wakefield, MA and founded in 2001, Vestmark supports over $1.5 trillion in assets and over 5 million accounts.
