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.

Part of this storyFirst-partyConfidence · Medium

Advance Auto Parts printed a second-quarter report and took -25% for it — and AutoZone fell the same day. One company's ledger ended up pricing the whole auto-parts aisle.

MechanismThe 8-K says one thing only: on August 20 the company put out a press release with its second-quarter results. The figures live in an exhibit; the filing body carries none of them — so this paragraph carries none either. The news landed premarket and the move was priced at the opening bell (1 ticker gapped), which is why no lag is measurable. The read-through is the interesting part: the same day carried a piece explaining why AutoZone dropped, and a sector note on consumer stocks sliding through the afternoon. A peer repricing on someone else's earnings says more than the size of the fall.

Event time: 2026-08-20 · premarket
Lag: priced at the bell — not measurable

This attribution rests on a first-party source — the issuer's own filing or announcement — and the timestamps line up.

Part of this storyUnattributedConfidence · Low

Moderna gave back -24%, its largest single-session drop in a hundred sessions — but the Dow was falling the same day, and not one first-party item about Moderna alone lines up with it.

MechanismThe break lands intraday at 15:30 UTC, not at the opening bell — so this was not an overnight headline priced at the open, it was selling during the session. Nothing in the window lines up on both timing and scope: no filing, no regulatory release. Two market-wide pieces sit alongside it that day — one on the Dow tumbling while miners and oil stocks caught a bid, one on yields rising and equities hitting their lowest in more than two weeks. Pinning a single name's giveback on the tape is a guess, not an attribution — which is why this row is badged unattributed instead of being handed a reason that merely sounds right.

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.
