CBOE Volatility Index (.VIX) is up .29 to 18.21 and looking to extend this week’s winning streak. After falling during 17 of 18 trading sessions, VIX is up 4.5 percent since Friday and might be seeing some strength due to upcoming expirations — VIX options a week from today and then the “Quadruple Witch” next Friday. In the options, noteworthy trades in the VIX today include two large blocks totaling 80K May 35 calls on the bid of 45 and 50 cents per contract. These blocks printed in morning action and, since it looks opening, might reflect expecations that VIX is unlikely to make a signficant move higher by the VIX May expiration (69 days.)
