Up 118.0% over 24 hours on 111.7× baseline volume — 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.

UBS cut NuScale to Sell and put both reasons in the headline: the build timeline and the cash burn. The 12:20 UTC story measured the decline at 3.3%; the 13:25 rewrite called it 5%. By the close SMR was -16% on the day — its largest single-day move in 100 days, on 5.9× baseline volume. The headlines spent the session chasing the price.

MechanismPut the order straight first. The downgrade landed before the US open, so SMR gapped — the lag on this story reads “gap,” not a number of minutes, because the price was reset in the first print of the session. Both reasons for the cut are clickable from this card: the headline of the source we selected names the build timeline and the cash burn. What has to be said plainly is that none of this is a company document — SMR filed nothing first-party this round, and every source listed on this card is a media report relaying sell-side research. That is why this card is tier secondary. It proves one thing only: that the news was public at that moment. We do not have the research note itself, so no price target and no model assumption gets printed here. What is worth recording is the trajectory of the headlines themselves: the 12:20 UTC piece said “down 3.3%,” the 13:25 piece said “down 5%,” and the day closed at 8.61 dollars, -16%, on 5.9× baseline volume, at a sigma of -2.7, ranking 1st among single-day moves in 100 days. The media measured a cross-section at the moment each story went out; we measure a full 24 hours. The numbers differ because they are measurements of different things, not because one of them is wrong. There is also the setup from the day before: on 09-10 Piper Sandler split the sector into tiers and Oklo, NuScale and X-Energy all dropped 5%. So this is not an isolated bar — it is the same set of small modular reactor names being re-sorted by the sell side on consecutive days. We have seen only the relays of both notes, so the sentence stops there.

Two of today’s top ten are really one event: HPE +12%, Dell +12%, both repriced in the gap at the opening bell. Neither lead our attributor picked lands on it: one is an 8-K Dell filed with the SEC the evening before, the other a piece published almost four hours after the gap whose subject is Ciena and Arista. We read that 8-K in full. It is about refinancing debt.

MechanismStart with what can be proved. Two names were repriced at the same instant in the same direction; 2 of them gapped straight at the bell, so the lag for this cluster cannot be measured and no number is printed for it. HPE closed at 62.09 dollars on 4.9× baseline volume; Dell closed at 567.29 dollars on 8.6×. These are two large-cap server makers repriced together on the same day, not a small float pushed around by a single order. The synchrony is the one thing this card measures cleanly. Now what cannot be proved. Dell’s 8-K reports an underwriting agreement: the company agreed with a syndicate of underwriters to issue several tranches of senior notes with different maturities, using the proceeds to repay a first-lien note maturing in 2026 and the remainder for general corporate purposes. That is a refinancing — swapping maturing debt for new debt — and it has no same-day causal link to how many servers get sold. Treating it as the reason for this move means reading the treasury department’s calendar as a demand signal. It carries the primary badge here only because it is the one company document anywhere in this cluster. HPE has the opposite problem: there is no first-party HPE document on this card at all, and the piece our attributor chose for it is headlined on whether Ciena’s backlog or Arista’s margins should carry your AI network bet — the subject is never this company, and it went out almost four hours after the gap. So this card does not name a cause. Everything else that landed on it — one report that RBC raised its price target on Dell, one asking what Dell had said before the stock multiplied several times over, two closing market wraps — was published after the gap. They are post-mortems, not triggers. We do not hand-edit the tier or the selected source: those fields are machine measurements, and editing them would stop this card from being reproducible. But it is written here, so that anyone reading the price has the sentence in hand: what we measured today is that two names moved together, not that we know why they moved.

Boyd Group +11% in a session — its largest single-day move in 100 days, on 7.9× baseline volume — while the 6-K it handed the SEC that morning is, in itself, a cover page. All the weight sits in the one exhibit it points to: a press release dated September 11 announcing a share repurchase programme.

MechanismThe sequence lines up cleanly. The 6-K reached EDGAR at 07:41 UTC; at 11:00 the press release announced a normal course issuer bid; a 12:02 report said the Toronto exchange had approved it; then the price was reset in the gap at the US open, closing at 90.4 dollars, +11%, on 7.9× baseline volume, at a sigma of 3.1, ranking 1st among single-day moves in 100 days. The news came out premarket and the repricing was complete at the bell, so the lag cannot be measured and the page prints a gap. But before calling that sequence a cause, look at what the first-party document actually is. The body of the 6-K is a cover page: the registrant’s name, its address, the check box for which annual report form it files, a signature, a date, and one line pointing at the single exhibit — the press release dated September 11. All the substance lives in that release, and what the release describes is a permission granted: a normal course issuer bid is authorisation to buy back your own shares on the open market up to a cap, not a purchase that has happened. Between the authorisation and the buying sit every future decision management has yet to make. So the honest sentence on this card is this: a first-party document exists, it precedes the move, it concerns returns to shareholders, and the timing fits exactly. Whether it is large enough to account for +11% and 7.9× volume is something we have no second piece of evidence to weigh — so we do not weigh it. A lead whose timing fits and a cause that has been demonstrated are still some distance apart.

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.
