Margins Each as a share of revenue. Gross: left after the direct cost of what was sold. Net: left after every cost. Free cash: free cash flow over revenue. A margin rising over years means the business keeps more of each dollar it sells. Methodology

Next report

Nov 11, 2026

Expected move The move, either way, the option market prices in through the next scheduled report: the at-the-money straddle for the first expiry that contains it, over the price. It includes the days around the report, so it slightly overstates the report alone. Methodology ±8.0% $1,055 – $1,239 by Nov 20, 2026
Usual move The median, over the company's last four reports, of how far the stock moved either way from the close before the filing to the close of the session after it. Methodology ±5.3% last 4: -2.4% · +7.3% · +3.4% · -11.9%
Expected against usual The move the options price through this report over the move the last four reports delivered. Above 1 the event is priced bigger than the company's own record; below 1, smaller. A price, not a forecast: it says what protection through the report costs, not which way the stock will go. Methodology Bigger than usual 1.5× the usual move

What options price now

Swings expected vs recent The daily swings the options are priced for (implied volatility) against the swings the stock actually had over the last 20 sessions (realised volatility). Bigger means options charge for more movement than the stock has been delivering; smaller, less. On a contract row, that contract's own implied volatility over the stock's realised. Methodology
Bigger 37.4% priced · 24.9% recent
Next month vs later At-the-money implied volatility for 8-45 day expiries over 46-90 day ones: whether options price the coming month as choppier or calmer than the two after it. Ahead of a report it usually reads choppier, and the extra comes out once the report is out. Methodology
Choppier
Crash protection What options that pay off in a fall cost against options that pay off in a rise (the 25-delta skew), compared with this company's own normal - the median of its stored nightly readings, once there are 20 - and with five sessions ago. Protection costs a little more than upside on most shares. More than usual means readers of the chain are paying up to insure against a drop; it does not say which way the stock will go. Methodology
past week: costs less
Positioning
Premium traded
$584,710 calls $466,465 · puts $118,245 · latest session
Puts against calls, by premium Money spent on puts divided by money spent on calls. Measured in dollars rather than contracts on purpose: counting contracts treats a hundred cheap lottery tickets as more meaningful than one large position, which is backwards. Methodology
0.25× -1.51 over the week
Open interest added The change over five sessions in option positions left open overnight, calls and puts. A rise means positions were added. It cannot say whether they were bought or sold, so more calls is not a vote for a rise: a call is as often sold against shares already held. Methodology
calls +154 · puts +841 past week
