In the future, could we experience a day in which the VIX rose more than 300 percent to triple-digit territory? I have asked this question to some financial experts, and some experts note that (unlike in 1987) we now have official circuit breakers to slow down intraday moves. On Dec. 21, 2007, the VIX closed at 18.47, and many “experts” probably would have said that the chances of VIX rising to record-breaking levels above 70 or 80 within the following year (with circuit-breakers) were extremely unlikely. However, on Oct. 24, 2008, the VIX did hit an intraday high of 89.53.
