Congressional stock trading makes headlines, but the mechanics are boring in a useful way. The STOCK Act of 2012 says members aren't exempt from insider trading laws and must disclose trades over $1,000 within 45 days.
The outrage usually skips the details. Filings show ranges, not exact dollars. Disclosures lag by weeks. And most members' trades are plain index funds or a spouse's managed account, not smoking guns. The system was built for transparency, not real-time surveillance, and it shows.
What is genuinely useful: spotting sector tilts. If several members on the same committee buy the same sector in a quarter, that's a pattern worth noting, whatever the motive. Committees see regulation before markets do, and their portfolios sometimes show it.
One more honest caveat: most research on congressional trading finds the outperformance, when it exists, concentrated in a handful of active traders. The median member's portfolio looks like a target-date fund. Don't build a strategy on the median; watch the outliers.
