Keystone Financial Services, LLC

The portfolio structure is highly modular, relying heavily on ETFs and pooled investment vehicles rather than a long tail of individual stock picks. With roughly 42% of the portfolio allocated to "Unknown" and "ETF" categories combined (based on the provided sector classification), it appears Keystone utilizes a "core-satellite" or fund-of-funds approach, outsourcing specific market exposures to specialized managers while maintaining direct exposure to a select group of mega-cap equities.
