Managed accounts are set for a major transformation as current models often benefit providers more than participants due to high fees. Employers must evaluate how providers personalize portfolios and whether participants actively engage with these features. 

While managed accounts generally offer strong investment management, fee structures can erode some of their value, requiring significant equity exposure increases to match target date fund returns. Personalized portfolio returns tend to fall within a narrow 5% to 7% range, with minor impacts from strategic asset allocation shifts. 

A subscription-based model could better align incentives, offering lower-cost options for less engaged participants while providing premium services for those seeking greater customization. Inconsistencies in provider methodologies, driven by factors like risk tolerance and retirement readiness, highlight the need for greater transparency. 

Finsum: This is an interesting strategy, but if done properly managed accounts are a great vehicle for retirement and defined contribution.
