Florida-based asset manager Polen illustrates how missing a mega winner in the
AI boom can reshape a firm: over four years its assets under management fell
about 60%, down nearly $50bn to roughly $33bn. The firm's six equity mutual
funds run concentrated portfolios; flagship Polen Growth Fund holds under 30
stocks and did not buy NVIDIA (NVDA.O), instead maintaining positions in
software names Adobe (ADBE.O), Salesforce (CRM.N) and ServiceNow (NOW.N). In a
June 2023 client letter Polen wrote “we believe that nearly all upside
opportunities currently visible have already been priced in by the market” on
NVIDIA; the stock then rose about 400% while an index tracking cloud software
fell roughly 3% over the same period. Polen says it reversed its prior bearish
view on AI chips at end-2025, acknowledged the misjudgment and began buying
related stocks.
