Misreading politician trade disclosures is the most common mistake new researchers make. The trade happened on the transaction date; you often learn about it only when the filing is published.
Transaction date vs filed date
- Transaction date: when the trade occurred
- Filed / disclosure date: when the form was submitted
Edge decays with delay. Always log both dates in your notes.
Amount brackets are ranges, not exact size
Many disclosures report ranges (for example $1,001–$15,000). Treat them as magnitude bands, not precise entries for sizing positions.
Asset type matters
Check whether the line item is:
- Common stock purchase or sale
- Option exercise
- SPAC or fund interest
- Spouse or dependent account
Mixing types creates false "senator bought tech" narratives.
Validate with a second source
Before acting on a headline:
- Open the original filing link
- Confirm ticker spelling
- Compare to market prices on the transaction window
- Check for subsequent amendments
ProBors surfaces structured fields so you spend less time parsing PDF tables.
