There seem to be times when you can predict volatility. Because people are hesitant to hold positions over the weekend, Friday afternoons should be relatively calm. Conversely, as people attempt to process the information from the past weekend, Monday mornings should harbor more uncertainty, causing people to pay a greater premium for options. I looked at about ten years worth of data for the VIX. Despite an overall decline in the VIX, the Monday close was consistently higher than the Friday open. from 2005 to present average price -- 12.71 average weekly gap up -- .31 for 2004 average price -- 15.69 average weekly gap up -- .42 for 2003 average price -- 22.28 average weekly gap up -- .62 from 1997-2002 average price -- 25.07 average weekly gap up -- .71 I also checked out prices for options for vix for the past three years. vix bid index (VWB) average price -- 119.69 average gap up -- 5.18 vix offer index (VWA) average price -- 133.35 average gap up -- 9.34 What is the best way to buy volatility? I've looked at the CBOE website and searched previous posts on Elite Trader, but I'm still not sure how to buy VIX futures or options. Could I use this as a guide for buying spreads for individual options? Also, what would some of the problems be with buying on Friday close and selling on Monday open (or vice versa)? Thanks in advance.
