Market Update 2/24/10
Over the past 2 weeks VIX and VIX futures came down significantly. VIX call options lost value over this time period.
For example the 25 March VIX call options were trading at $3 on Feb 8. Today they closed at $0.6.
Here are the factors driving the price change:
-the March VIX futures went down from 26.2 to 21.7 today. This caused a loss of $2.3 in the price of the VIX call options
-options loose value over time, this option lost about $0.6 over this time period
-the option gained about $0.5 due to the increase in the implied volatility (from 73% to 88%). This is something unique to VIX options as I mentioned in my prior post, the IV goes up as they get closer to expiration. It is interesting how this reduces the cost of carry (theta) of these options.
If you add these up you get to the price difference of $2.4.
In case you were shorting this monster you are a happy guy.
Introduction to VIX options (Part 1)
One of my goals with this blog is to explore the VIX options, which are one of the most complex instruments available for individual investors.
Volatility is certainly a fascinating subject. Imagine a formula for gauging human emotion – what could be more interesting than that?
Implied volatility of VIX options is the second derivative of the price of the S&P 500. Unless you like math, it gives you a headache just thinking about it.
Even CBOE admits “calculating exact theoretical values for VIX options can be very complex”.
Why is so complex?
First reason:
CBOE decided to base the price of VIX options not on the current level of the VIX, but on the anticipated level of the VIX at expiration. The price of any index option depends on the forward price of the index and the expected shape of the forward price distribution. Forward prices of option volatility exhibit a "term structure", meaning that the prices of options expiring on different dates may imply different volatility estimates.
VIX options investors look at the prices of the VIX futures to gain a better general idea of how the market is estimating the forward value of VIX.
As I mentioned before on average the VIX term structure is upward sloping, probably due to investor demand for volatility hedging.
Historically, VIX futures have tended to be less volatile, on average, than the VIX index itself. The volatility is lower for longer dated futures.
In option language this means that if you hold a VIX option you lose money due to theta but you make money due to higher implied volatility as you get closer to expiration.
