Where it stands today
Where one-month protection (30-day implied volatility) sits within its past-year range, 0 the cheapest and 100 the dearest. Protection on Dell Technologies is now in the middle of the past year.
The one-year sits 6.88 points above the 30-day, the usual shape: a longer policy covers more.
Centred on the previous close of 574, option prices imply 553.23 to 594.77 at this week's expiry. A close outside it at expiry means the option sellers lose.
Calls outtraded puts. It counts contracts, not direction: a put buyer may be insuring shares they own.

| Close | 566.45 | ||
| Expected move, low | 553.23 | −2.33% | Centred on the previous close: the implied bottom at this week's expiry. |

同一条供应链买内存的涨一成、卖内存的跌三个点，短缺的价没落在卖方头上（DELL +11.98 / 2.43x、HPE +12.44、SMCI +7.28 / 1.73x 对 SNDK −3.50、STX −3.73、WDC −2.98）；回本时间表拿得出来的分两种：能借到钱的涨（戴尔发债超额认购），借钱比收钱快的被交货（ORCL 开 +7.51 高 165.99 收 150.28 −1.74 / 1.41x / 区间位 3%）
Test: 下周 SNDK/MU 反弹而 DELL 回吐一半 ⇒ 今日两头为戴尔三条消息（RBC 首评/发债超额/进标普 100），收回；ORCL 收复 159.59 ⇒ 消息日换手非交货，收回。只引官方日线收盘与跳空表量比
一半：SNDK 09-16 1519.97→09-18 1791.82、MU 926.55→1015.80 反弹成立，DELL 563.29→568.06 未回吐 ⇒ 收回条件只成立一半；闪迪 140 亿回购日打断了「卖内存的跌」那句

RMS.PA· The one-year percentile and the 30-day and one-year implied vols come from two different sources; each is compared only with its own past, and the two are never spliced together.
· The 30-day and one-year vols are constant-maturity: interpolated between the two nearest expiries to exactly 30 and 365 days, read once before each close.
· A big-print row is one contract's full-day total, not a single trade. Without per-trade timestamps or aggressor side we state premium traded only.
· Every reading is cross-checked against two independent sources and updated once after the close. Raw data is not provided on this site.
· Data and information only; not investment advice; no buy or sell recommendations.
