What options price now
- Expected 1-month range The at-the-money straddle for the expiry nearest a month out, as a share of the price: the move, either way, the option market is pricing by then. The range is the price plus and minus that move; the stock ends inside it a little more often than not. Methodology
- $304 – $340 ±5.5% by Nov 20, 2026
- 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
- About the same 27.8% priced · 29.0% 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
- $1.1M calls $760,528 · puts $319,430 · latest session
- 0.42× +0.28 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 +230 · puts +505 past week
