How does Vestmark support Vanguard Custom Model Portfolios?
Vestmark provides the essential infrastructure for Vanguard Custom Model Portfolios, focusing on trading, tax-management, and advisor-service capabilities.

What benefits does this offer to Registered Investment Advisors?
The partnership allows RIAs to modify Vanguard models to reflect specific client preferences regarding investment products and management styles. By utilizing Vestmark's platform, advisors can deliver higher levels of personalization without increasing operational complexity. This is particularly relevant as Vestmark currently supports more than 72,000 financial advisors and more than five million investor accounts.
“Vanguard has built its reputation around disciplined investing, low costs and long-term investor outcomes,” said Karl Roessner, Chief Executive Officer at Vestmark. “By combining that investment expertise with Vestmark’s portfolio-management, trading and tax-management infrastructure, we can help RIAs deliver greater personalization without adding operational complexity. We are proud to support Vanguard as they bring this new offering to the RIA market.”

It is a significant validation of Vestmark's UMA and tax-optimization capabilities in a competitive wealthtech landscape.
