Down 55.8% over 24 hours — no first-party event in the window lines up on both timing and scope.

Nothing in the window before the move began lines up on both timing and scope — not a first-party filing, not a press report. We would rather leave this blank than supply a reason that merely sounds plausible.

COO -15% in one session, the largest single-day move it has printed in 100 days — and the “cause” our attributor picked is a Barron’s column whose own headline concedes Barron’s got Cooper wrong. It went out at 18:24 UTC and was logged 66 minutes ahead of the break. The first-party document had been sitting on EDGAR since the close of the evening before: a nine-month strategic review closed, and the board unanimously decided not to sell CooperSurgical.

MechanismPut the order straight first. After the close the previous evening, the company sent an 8-K to the SEC (linked from the COO row above) carrying two separate pieces of news: results for the most recent fiscal quarter, and the conclusion of the strategic review it had opened last December. The second press release attached to that filing is blunt — the board evaluated a sale of CooperSurgical, ran a process involving numerous parties, and unanimously concluded that holding on serves shareholders better than transacting at the offers on the table. It also names two temporary factors it believes depressed the valuation: a competitive entrant to the non-hormonal IUD market, and the fertility litigation settlement the company recently closed. The board widened the share repurchase authorization at the same time — but a buyback buys back stock, not a deal that is no longer going to happen. The option that had been hanging over the tape since late last year was closed by the company itself. The price moved in that order too. The decline was essentially complete in the gap at the 09-10 open; for the rest of the session the stock simply sat near where it opened (you can see it on the sparkline), on 6.7× baseline volume, at a sigma of -7.9, ranking 1st among single-day moves in 100 days, closing at 54.17 dollars. Now the flaw in this card itself. The attributor read the 18:24 UTC Barron’s piece as the catalyst, measured a 66-minute lag, and marked the break at 19:30 UTC — which is the heaviest-volume hour of the session, not the moment the price was reset. But that piece is headlined on getting Cooper wrong and on the contact-lens stock now looking cheap: it is a post-mortem written after the fall, not the reason for it, and the first-party document beat it by the better part of a day. We do not hand-edit that label — the tier and the lag are machine measurements, and editing them would stop this card from being a reproducible one. But it is written down here: the 66 minutes on the page measure the distance between an after-the-fact column and a late-session volume bar, not causation.

Timestamp precision: To the minute
Lag: 66 min

Press coverage only — no first-party filing came back. Confidence is therefore capped at medium: we know what happened, just not from the party it happened to.

Methodology

Evidence tier

First-partyA machine-readable endpoint run by the issuer, the exchange or the regulator itself.
Cross-verifiedTwo mutually independent sources report the same figure.
Secondary (media)Press coverage. Listed as a lead only; its figures never enter a measured field.
UnattributedNo catalyst was found. That is the normal case, not a failure.

Change: For crypto this is the exchange's rolling 24-hour figure (last price over the price 24 hours ago). For US equities it is the session change, previous close to last: US markets are shut about 17.5 hours a day, so a literal 24-hour window would fold two sessions into one number.
Volume vs baseline: Volume of the breakout bar divided by the median of the prior 20 bars. The baseline is a median, not a mean, so the spike cannot inflate its own denominator.
Sigma move: This move measured in standard deviations of the instrument's own 30-day realised volatility. The larger the number, the less it looks like ordinary noise.
Rank in past 100 days: Where this move ranks among the past 100 complete trading days. Rank 1 means the biggest in a hundred sessions.
Lag: Time between the catalyst event and the start of the move. If the event lands after the move began, the entry is marked unattributed.
Gap at the open: The news broke before the bell, so the repricing was finished by the time trading opened. This row's move starts at the opening bell itself, which means there is no lag to measure — and we do not print one.
Measured from: Price, volume and range for this row are measured here.
Leads: The events below pass the scope test but not the timing one — listed as leads, not as attributions.
