ONC BeOne Medicines Ltd. BEARISH conviction 1

2026-06-16: OYLER JOHN (Director, Chief Executive Officer) — sell-to-cover (tax withholding on a vest) — $980.7K of ONC (open-market, Form 4, code S) [sold to satisfy tax withholding on an RSU vest per the leg's own footnote — timing and size set by the vest and the tax rate, not by the seller] [CORRECTION 2026-08-28: the sentence opened on 2026-06-18, the day EDGAR indexed this filing. A sibyl head date is the TRADE date (owner ruling 2026-08-22), and the earliest transaction date this filing reports for the sell legs behind this row is 2026-06-16 — now both the head date and the row's traded_date column, which was empty. No figure, actor or mechanic changed. Original text in signal_events] [CORRECTION 2026-08-28: published as a discretionary sell by a CEO. Every one of the filing's three sell legs cites footnote F7: "The sale was effected pursuant to a mandatory tax withholding provision in the Reporting Person's restricted share unit award agreement in connection with the vesting of a restricted share unit award previously granted to the Reporting Person." There are no other sell legs, so 100% of the $980.7K is mandatory withholding on a vest. The sell-to-cover reader missed it because every arm of its pattern was anchored on the filer saying "to cover" or "to satisfy", and this filer says neither; four sibling rows in the same 2026-08-26 sweep whose filers did use those words were re-classed correctly. The dollars and the actor are unchanged; the word withdrawn is "discretionary". The sentence above is the one the fixed reader publishes for this filing today, re-derived from the filing itself for this repair rather than edited. Original text in signal_events]

What these fields mean

Direction
Direction (BULLISH/BEARISH) classifies the event, not the price. It is not a forecast, and no scout's direction has been validated as predictive.
Conviction
Confidence is a heuristic conviction score, not a calibrated probability. On a single filing it is the scout's own 1-5 grade; on a row that rolls several filings together it is their SUM and has no ceiling, so it can read above 5. The stored number is published as it stands — never clamped, never hidden.
Dates
Dates are rendered exactly as filed. A sibyl row leads with the TRADE date the Form 4 reports; a pelosi row shows the member's trade date and the date the disclosure was filed, which are rarely the same day. "Flagged" is the day this feed first published the row.
Backfilled rows
A row marked "already old news when flagged" reached the feed after the fact. It is a record of a filing, not of a timely catch.
Sources
Every row links to the filing it was read from — an SEC Form 4 on EDGAR, or the disclosure document filed with the House Clerk or the Senate. A row whose source document this feed cannot link to is left off it.
