California withheld the wildfire liability protections its utilities had been counting on: Edison International -23% on the session, PG&E -20%, both gapping on the same opening bell, Edison's volume at 18.7 times baseline. That evening the top DD title on r/wallstreetbets argued the other side — today's 23% crash is a forced-selling overreaction, not a fundamental one.

MechanismTwo names gapped in the same minute and neither reported earnings — what got repriced here is not a company, it is the regulatory regime they share. The coverage that day is consistent: California's wildfire legislation landed, and the piece the utilities most wanted, liability protection, was left out of it, so California utility shares fell together. PG&E did not stay quiet either: before the open it filed an 8-K with EDGAR (Regulation FD disclosure) saying the company does not believe the legislation adequately addresses the financing risks created by California's current wildfire liability framework, and scheduling an investor call two days out. The badges still follow what can vouch for the move on this card: Edison's row is graded secondary on press coverage, PG&E's row had no first-party event lining up on both time and scope and is honestly marked unattributed, and the story takes the weaker of the two legs rather than letting one vouch for the other. The tape had a second thread that day — crude oil and the Middle East — and that explains an index, not a 23% move in a single name, so we do not write it into this story's cause. The text of the bill and the size of the wildfire fund are the kind of figures no link on this card reaches, so we print none of them. Both gapped at the bell (13:30 UTC), so the lag is once again not measurable.

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.

Aon -9.5% on the session with volume at 7.6 times baseline — and what it announced that day was an expansion: Item 1.01 of its 8-K reports a signed merger agreement to buy a middle-market insurance brokerage for cash. The market's first vote on the acquirer was to mark it down by nearly a tenth.

MechanismThe thing worth pausing on is the direction: the news itself is expansion, and the price answered by selling the acquirer down by nearly a tenth on 7.6 times its baseline volume. Both halves are in the 8-K. Item 1.01 reports a merger agreement with the company being acquired, with completion subject to customary closing conditions and regulatory approvals; Item 7.01 reports that a press release went out the same day and that investors got a supplemental presentation. This is the ordinary half of any acquisition — the company being bought is not on the tape, and the company doing the buying pays a discount up front for the price, the leverage and the integration years. The consideration itself lives in the merger agreement, and none of the text laid out on this card reaches that figure: the link to the 8-K is right here and the number is inside it, not in the title we display, so we do not print it in this paragraph. The badge on this row is primary because the first-party document was available the same day: the 8-K reached EDGAR before the bell, which is the hardest kind of evidence to get on a single name — and deal filings, almost without exception, are filed premarket. The cost comes with it: the news was premarket, the move starts exactly on the opening bell (13:30 UTC), the lag cannot be measured and we will not invent one.

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.
