The VIX closed 7% higher to 15 today, whicu is still a remarkably low level though. Even a move to VIX'16 looks difficult tomorrow, never mind the notion of a multi-day VIX rally to the July high of 21.
Until the market is below the recent cycle low SP'1354, any VIX increases are to be treated with high caution.
From a doomster perspective, I remain very much in the mindset of 'give me a call if ya see sp'1340s, with VIX 21+'. Until then...it remains a tricky and dangerous market for the bears to be part of.
