Dissemination of the Cboe Volatility Index Spot Value

February 06, 2018 11:31:10

Summary
Effective, February 6, 2018, Cboe Exchange, Inc. (Cboe(r)), in its capacity as the reporting authority for the Cboe Volatility Index(r) (VIX(r) Index), modified the below underlined values in relation to the filtering process on VIX Index spot values during Cboe's regular trading hours (Cboe RTH) and extended trading hours (Cboe ETH) sessions. Values for the VIX Index are published approximately every 15 seconds during Cboe RTH from 8:30 a.m. to 3:15 p.m. Chicago time and during Cboe ETH from 2:15 a.m. to 8:15 a.m. Chicago time. This notice updates Cboe Options Information Circular IC17-062 and CFE Information Circular IC 17-051.

Filtering Process
The filtering process will utilize the following parameters:
1. The first VIX Index spot value calculated during the Cboe RTH session or the Cboe ETH session shall be the "baseline" VIX Index spot value.
2. Any value calculated after and within two (2) minutes of such baseline that is higher than the baseline value or lower than the baseline value by 0.49 or less volatility index points shall become the new baseline.
3. If values calculated after and within two (2) minutes of a baseline are lower than the baseline by 0.50 or more volatility index points, then the baseline VIX Index spot value will be republished as the VIX Index spot value.
4. If the published VIX Index spot values remain the same for a period of two (2) minutes because the calculated values are 0.50 or more volatility points lower than the baseline, the first value calculated after the two minute period shall become the new baseline VIX Index spot value.
5. Filtering is currently applied during the Cboe ETH session and is being extended to the Cboe RTH session.
6. Filtering will not apply to the first VIX Index spot value calculated at the start of the Cboe RTH session or the first VIX Index spot value calculated at the start of the Cboe ETH session; rather, as previously noted, the first VIX Index spot value of the Cboe RTH session (or the Cboe ETH session) is the initial baseline VIX Index spot value. This means that all other VIX Index spot values calculated during Cboe RTH and Cboe ETH will be determined using the filtering process.
