Direct indexing is increasingly popular as investors seek personalized options and lower costs. This method, which involves owning a representative sample of securities in an index, offers benefits like reduced costs, individual tax lot ownership, and increased tax efficiencies.

However, to fully realize these benefits, direct indexing should be implemented within a single multi-manager account (UMA) rather than standalone accounts. This approach allows for effective tax loss harvesting, consistent exposure to the reference index, and avoids disallowed losses due to wash sales. 

Managing a portfolio within a UMA also simplifies administration and enhances rebalancing and asset allocation efficiency. When switching firms, advisors can use UMAs to minimize capital gains taxes for clients by absorbing satellite holdings into the core direct index.

Finsum: We know the benefits of tax-alpha but these account types could give investors an additional edge.
