VIX Index is not directly investable

� The VIX Index is the result of a mathematical formula based on options prices.

� The replicating portfolio of options will give the value of VIX2, not the VIX

� An option portfolio worth the VIX today will have to be rebalanced to match the VIX tomorrow. It will suffer time decay and rebalancing costs.

There is no portfolio of assets/derivatives worth the VIX Index every day.

You cannot buy the VIX.

� How can investors get exposure to the VIX Index?

� VIX Futures

� VIX Options

Sep-11 VIX Future’s value is today’s expectation of what the VIX will be worth on the 21 Sep-11, as it will be implied on that day by the Oct-11 SPX option.

� Since the VIX is not investable, there is no cash and carry strategy to link the VIX spot and VIX future prices.

� The settlement value is a Special Opening Quotation of VIX (Bloomberg: VRO Index) computed using a specific auction on the listed options of the replicating portfolio. So you can print the cash settlement of the future.

� Finding the right balance between short-term volatility and long-term volatility

� Front month futures are very reactive, but the rolling costs are generally more expensive due to a steeper contango on the front. Moreover the high volatility makes entry and exit timing more difficult.

� Longer term futures are cheaper to roll but display lesser reactivity

� The performance of rolling a long future position can be broken down into

� Spot return : Price return of one future over one roll period

� Roll return : Impact of switching from one future to the next
