The VIX is up 5.85 today from a level of 24.76 = current level of 30.60
However, the Nov. 25 call is only up 1.75 to 3.75.
Why is the call not equal to "the in the money"? which would be 5.60.
Because options on the VIX are European style options, which means they're priced based on the expected forward value of VIX at expiration. Unlike American style options, they're only exercised on the expiration date.
Although the spot VIX went up to 30.60 today, the Nov. VIX futures only went up to 27.85. So the Nov. 25 call at 3.75 is correctly priced.
