- Report’s part
- The report’s own share of what the options priced the day before, taken from two or more expiries.
- ColumnsPriced
- Realized
- C2C is the previous close to the next close; By 10:00, the 09:55–10:05 ET average price against the previous close, never substituted from the open when it is missing.

- Chart
- The grey band is what the options priced and the marks are what happened, on a ±25% scale.
- ColumnsPriced · realized · ±25%
- Crush
- How far implied volatility fell in the report’s expiry. ATM is at the strike nearest the price, day before to day after at 15:46, read late in the session, so it does not compare with a figure read at the open. As-sold is at the strike a position was already holding; a blank there is not a small crush, because after a big move that strike is often no longer quoted the day after. Open is backed out of the option’s own 10:00 price the next morning.
- ColumnsATMAs-soldOpen
- Forecast
- Pred. is the crush we wrote the day before the report and never changed, marked rec where it was rebuilt from history. Error is what happened minus the forecast, graded against the collapse at the new strike, in points of the crush.
- ColumnsPred.Error
- Sold
- P&L: sold at the bid the day before and bought back at the 10:00 ask, as a share of the premium collected. A record of what happened, not a recommendation.
- ColumnsP&L
- The rest of each reportThe quoted move before the split, the drift from the open to three sessions after, the 10:00 as-sold and 30-day crushes, the skew before and after, and the cover mark, for each of BRK_B’s 17 reports.
- What selling it keptWhat selling BRK_B’s straddle the day before kept when it was bought back at the open, at 10:00 and at the close: the average, the median, the worst report and the losses, over its last 12 reports.
- After the openWhether BRK_B kept moving after the open or faded back by 10:00, and what the stored numbers say about the wings and the calendar: the typical distance to a wing, the slope at entry and the front-leg crush that followed.
We publish flagged reports instead of dropping them. A marker on one report says little about the company and one on most of them says a lot, so the count is what tells them apart.
Every marker on this name, counted against the report it touched, newest first as in the history above. The first column is the current reading.
Not known yet: the report has not settled, so a marker set after it cannot be read.

What each marker means15 markers
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.Affects Crush (re-struck)
macro event in the 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.Affects Implied (event)
reported off-session The report date is not an exchange session — some names report on Saturdays — so the window was resolved against the sessions bracketing it. The reading is correct; what differs is that the close-to-close move spans a weekend or a holiday.Affects Reported
next-morning price from quotes 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.Affects Crush at 10:00
gapped past the wings 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.Affects Crush at 10:00 (as sold)
no prediction No predicted crush could be frozen for this print, so it has no entry in the scored accuracy record. Never filled in afterwards — a prediction written after the outcome is not one.Affects Predicted crush · Error
skew contamination The gap between the strike sold and where the stock ended up is large enough that the as-sold crush cannot stand in for the comparable one, so this print carries no scored open crush.Affects Accuracy record
wide decomposition band The decomposed implied move has a wide confidence band on this row. The number is published and kept off the board’s sort, because a sort cannot express an error bar; where its rank is shown, it is marked ≈.Affects Implied (event)
noisy IV rank This name’s quote width is large against its own 52-week volatility range, so the rank carries a read error worth noting. A true property of a quiet name, not a defect — the rank itself is computed normally.Affects IV rank
no trade at the cover The option legs did not trade at the 10:00 cover anchor, so the crush there could not be measured. It comes from the tape, not an outage, so it is permanent and counts in the published coverage ratio.Affects Crush at 10:00
no re-struck cover IV The comparable at-the-money volatility could not be read at the 10:00 anchor, so only the as-sold contract is available there.Affects Crush at 10:00
thin trade at the cover 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.Affects Crush at 10:00
no 10:00 tape The equity minute bars behind the 10:00 anchor do not exist for this session, so the anchor is blank and stays blank. It is never substituted from the opening price: a history with two different anchors mixed together is worse than a shorter one.Affects By 10:00 · Crush at 10:00
an anchor was refused 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.Affects Crush at 10:00
iV rose through the print Implied volatility went up across the event rather than collapsing — rare but real, usually guidance withdrawn or a second catalyst introduced. Shown, and kept out of the scored accuracy record rather than corrected.Affects Accuracy record
