How to read: Size bucket from current 13F-filed portfolio weight. Trend bucket from the last 2 quarters of move activity (net delta >5% in either direction = building/trimming; new = first-appearance this quarter; exit pending = trimmed >50% last quarter). Data lag: SEC 13F filings are reported 45 days after quarter-end. This is descriptive intelligence — not investment advice.
