Summary

The four offerings that constitute the MFS target-risk series–Aggressive Growth Allocation, Growth Allocation, Moderate Allocation, and Conservative Allocation–feature a durable process and compelling underlying funds. Lead manager Joe Flaherty’s June 2025 retirement does not alter our conviction in this strategy, given the firm’s prudent succession planning.
