Ummm, because you are comparing apples to oranges! The "old" VIX (circa 1987) is NOT the same measurement of today. The CBOE has a nice FAQ on their website about the differences. IIRC - the "max" from 2000 - 2002" is like 45. The "daily avg." today is well above 60 - BY THE NEW MEASUREMENT. Aside from that, the VIX is kind of BS - it doesn't so much measure volatility as it does options trading in the S&P...which is NOT necessarily "market volatility" as measured by volume or price changes in equites - IMHO.
