Customized solutions are powerful portfolio-management tools, but they can be time-consuming to implement. Our Custom Core solutions make custom direct indexing simple and scalable, freeing up time to grow your business and deepen client relationships.
Custom Core is a passive portfolio of stocks that adheres to a client-chosen benchmark, delivered as a separately managed account (SMA). With SMAs clients own each individual underlying security directly, allowing them to have a high degree of personalization based on their situations and needs.
