SNDK earnings: an expected move of 9.8%, an actual move of 8.6%.Averages over its last seven reports. Here they are.
Every Sandisk earnings report since May 2025: the expected move the options priced the day before, how far the stock moved by the close and by 10:00 the next morning, and the IV crush afterwards, how far implied volatility fell. We read option prices from real quotes at 15:46 ET. Definitions on the methodology page.

- Report’s part
- The report’s share of what options priced at 15:46 ET the day before, taken from two or more expiries.
- ColumnsPriced
- Rank
- Where the report’s part sits among SNDK’s own earlier reports, up to twelve, from 0 to 100. Rich and cheap mark the top and bottom of that range. It needs eight earlier reports with a 10:00 move, so the oldest rows have none.
- ColumnsRank
- Realized
- C2C is the move to the next close; By 10:00, the move to 10:00 the next morning.

- Chart
- The grey band is what the options priced, the dark mark where the stock closed, the bar where it stood at 10:00, on a ±20% scale.
- ColumnsPriced · realized · ±20%
- Crush
- How far implied volatility fell in the report’s expiry, from 15:46 ET the day before to the day after: at the new strike ATM and at the old one As-sold. Open reads it from the option’s 10:00 quotes the next morning, and is blank where there was none.

- Pred. is the crush we published the day before, graded on the public record. Error is what happened minus the forecast, in points of the crush.

to the closein betweenClosing prices miss the open
If you hold through the report you meet the open, not the close. We publish both: the move from one close to the next, and where the stock stood at 10:00 the next morning.
the reportordinaryOption prices cover more than the report
An expiry a week out also carries a week of ordinary movement. Comparing two expiries that both contain the report separates the two, and the report's share is the priced move.
the one that movedwhat 30 days averageWe measure the expiry that moved
A 30-day average mixes the expiry holding the report with expiries it never reaches, so it reads shallower than what you held. We read the expiry that holds the report, the day before and the day after, at both strikes.
One expiry contains the report. The 30-day figure is an average that also covers expiries the report never reaches. Every column below leans the same way, so the gap shows on each report, not only in the median.
Each row is one report: the band is what the options priced, the mark is where the stock closed, and the bar runs to where it stood at 10:00 the next morning. On 1 of 7 reports with both, the close and 10:00 pointed opposite ways.
Where the 10:00 number is missing, the cell stays blank instead of borrowing the close, and the data-quality grid below says why. How far apart the two run differs from company to company; this window measures it for SNDK.
The split reads the report out of the gap between the two lines. The small figure under each date is how many trading sessions the expiry holding the report had left. A shorter one carries the same report over fewer days, so it reads higher without the report being priced any bigger.
Drawn for the last twelve reports, like the other figures on this page. It is history; the current curve is on the board.
Counted over the 7 reports shown. One marker is on every report (macro event in the window), so it describes SNDK rather than any one quarter. The other nine are on between one and six reports.
Every marker on the reports above is counted here, one cell per report, newest first as in the history table.

What each marker means10 markers
Shown, kept off the board’s sort
- thin trade at the cover3 of 7
open_crush_thin_trade - Too few prints stand behind the 10:00 anchor for it to be a reliable price. The crush is shown and kept out of the rankings.
- Lands inOpen
- derived numbers unreliable1 of 7
derived_unreliable - Quotes on this name were too wide — or a 25Δ wing was missing — for the derived numbers on this row to be trusted: implied move, decomposition, crush and skew. Shown, kept off the board’s sort, and marked ≈ where its rank is shown.
- Lands inThe derived columns
- wide straddle quote1 of 7
wide_quote - The T−1 straddle’s bid-ask spread was wide relative to its own price, so every number read off that quote inherits the width. Published on purpose — the friction is real — but kept off the board’s sort, and marked ≈ where its rank is shown.
- Lands inImplied (naive)Short-straddle P&Lon the ticker page, not this one
Shown as measured
- macro event in the windowevery report
decomp_macro_window - A scheduled macro event (a CPI print, an FOMC day) falls inside the decomposition window, so a little of the volatility attributed to the event belongs to the calendar instead.
- Lands inPriced move
- held to expiry6 of 7
cover_mark_settled - The straddle that was sold expired at one of these closes, so its price there is its settlement value: the distance from the stock to the strike. That exit pays no bid/ask spread, and it ignores the cost of being assigned stock on the in-the-money leg.
- Lands inShort-straddle P&Lon the ticker page, not this one
- crush expiry substituted6 of 7
crush_expiry_substituted - The expiry that would have been measured was not available on both sides of the print, so a neighbouring one stood in. The crush is real; it is measured on a slightly different contract than the label implies.
- Lands inATM
- 30-day IV extrapolated1 of 7
iv30_extrapolated - No pair of listed expiries brackets 30 days, so the 30-day volatility was extrapolated more than a week past the nearest one rather than interpolated. A shorter reach is not flagged: it moves the number by well under one volatility point.
- Lands in30-day figureIV rankon the ticker page
- an anchor was refused1 of 7
open_crush_anchor_unreliable - At least one observation behind the 10:00 crush was rejected: a price below intrinsic, a crossed quote, or a solve that did not converge. The number here was measured from the anchors that did invert, and is scored normally.
- Lands inOpen
- gapped past the wings1 of 7
open_crush_gap_otm - The stock gapped far enough that the contract sold at T−1 is no longer near the money at the cover, so the as-sold crush there is partly a move along the smile rather than a collapse in volatility.
- Lands inOpen
- next-morning price from quotes1 of 7
open_crush_restruck_quoted - The option at the 10:00 strike did not trade on both sides between 09:55 and 10:05, so the next-morning volatility was read from the midpoint of its quoted bid and ask over the same ten minutes. Used only when both sides were quoted and the quote was less than 50% wide.
