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 BCYC 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.

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.
