📈 Vector 1 · Personal Enrichment trade-based
Scale-first: 162 total trades with $90K volume (5y, deduplicated), averaging $47.6K per trade, capped at $100K positions.

No sector anomaly meets the threshold (≥10pt divergence on ≥50 trades), as the `PRE-COMPUTED SECTOR ANOMALIES` array is empty. His primary sectors are healthcare (24 trades), consumer cyclical (22 trades), and energy (16 trades) (`get_politician_intelligence.profile.primary_sectors` and `sector_expertise`).
