Insider flow: Selling only — a count of disclosed transactions, not a rating or a recommendation.

Insider transaction timeline

Every reported transaction, positioned by trade date. Purchases sit above the axis, sales below; circle area is proportional to dollar value. No share-price line is drawn — this feed carries transaction prices only, and a price history inferred from them would imply market data the filings do not contain.

Not available for TDG today: no reported open-market purchases in this window, so there is no insider cost basis to compute; no research case — nothing here has cleared the scoring threshold. Both appear on this page on their own if that changes.

A free account opens all of it.

Not financial advice. This page reports public filings and past research output. It is not a recommendation to buy or sell, and no price target here is a prediction. Trade at your own risk.
