The CBOE announced they are adding half-point strikes for the CBOE Volatility Index (VIX) options. The half-point strikes will be listed for the near-term expiration month and in the strike price range of 10 to 15 (i.e. 10.5, 11.5, 12.5, 13.5 and 14.5 strikes).
The CBOE will keep half-point strikes (between 10 and 15) on a continual basis. The CBOE said customers have been asking for the half-point strikes. VXST already has half-point strikes.
