SEC Form 4 Insider Trading Tracker
Parses SEC Form 4 filings to expose actual insider transactions: CEO/CFO/Director open-market buys & sells, options exercises, awards. Returns ticker, insider name, role, transaction code, shares, price, USD value. Strong quant signal source.
Why this exists
When a CEO buys $5M of their own stock on the open market, the stock tends to outperform over the next 12 months. This pattern — and dozens of others — drive a whole class of quant strategies.
The data is free at SEC EDGAR — but parsing it requires:
- Watching the Form 4 atom feed
- For each filing, fetching and parsing the underlying ownership XML
- Decoding transaction codes (P/S/A/M/F/G/D/C/X)
This actor automates the whole pipeline and returns one clean row per transaction.
What you get per row

officer_title | Chief Financial Officer | |
is_ten_percent_owner | false | |

txn_meaning | Open-market purchase | decoded |

SEC Transaction Codes (decoded)
| Code | Meaning |
|---|---|
| P | Open-market purchase ← strong bullish signal |
| S | Open-market sale |
| A | Grant / award (compensation) |
| M | Option exercise → common stock |
| F | Tax-withholding payment |
| G | Gift |
| D | Disposition to issuer |
| C | Conversion of derivative |
| X | Exercise of in-the-money derivative |
The onlyBuys filter keeps just A (acquisitions) — useful for filtering noise.
