- Costco (COST): Shares decreased by 0.84%.

Investment Strategy and Outlook
The portfolio's strategy appears focused on investing in large, established companies across technology, communication services, and consumer sectors. The high concentration in Technology (33.47%) and Communication Services (27.63%) suggests a preference for growth-oriented and digital infrastructure companies.
The inclusion of Costco, a stable consumer staple, alongside Amazon, a cyclical consumer stock, indicates some diversification within the consumer space. However, the overall portfolio remains heavily concentrated in a select number of large-cap stocks, particularly in the technology and communication services sectors.
Conclusion
Frederick Rowe's portfolio, as of March 31, 2026, is characterized by significant concentration in top holdings, particularly in large technology and communication services companies. While the portfolio includes exposure to consumer and financial services sectors, the recent reduction in shares across most holdings warrants monitoring. The strategy favors established, large-cap entities, but carries the inherent risks associated with high stock concentration.
