As I mentioned in James talk thread - because of the delays imposed on us as to when our IFT becomes effective and when we get the closing prices for the day of the funds, IMO, it is just about impossible to do any timing regarding when to buy and sell your position in any particular fund.
But there is one exception, when the VIX reaches its 200 day average which is 13.02 today, that is time IMO to get out ASAP. Needs to be watched closely.
There is a question in my mind when to buy back in also once there is a pullback. Not necessary to wait until the VIX goes below the 200 day average. Looks like one can use the peak of its 20 day average to determine a good buying opportunity but isn't terribly precise. I'm still looking at that.
Reason I'm still looking is that I think it is a matter of WHEN, not IF we're going to have another pullback that will be reflected in VIX prices. Given the price of the VIX today, I don't think it will be today.
Also, to make the problem more complicated, it appears there has been occasions where there is a significant run-up just before the VIX goes thru the roof. Timing this run-up given the delays of our IFT is one of the factors making the usage of the VIX complicated. We could be seeing that "run-up" right now.
My crude attempt to understand correlation between Fund prices and VIX quote for June 3, 2003 thru Dec 15, 2006----
Number of data points and percentage of total number of all data pts
(885 total data pts)
F - entries matched direction of VIX---------366-------------41.36%
F - entries matching Opposite dir of VIX-----519-------------58.64%
C - entries matched direction of VIX--------173-------------19.55%
C - entries matching Opposite dir of VIX-----712-------------80.45%
S - entries matched direction of VIX--------216--------------24.41%
S - entries matching Opposite dir of VIX-----669--------------75.59%
I - entries matched direction of VIX---------331--------------37.40%
I - entries matching Opposite dir of VIX-----554---------------62.60%
I've attached a pdf file of an Excel chart from September til now to give you a closer look at the correlation between VIX and S fund. Meant to give an idea. I have Excel data but to extract it (because of all the dependencies with my other data) is a bit more time consuming then I like given my lack of experience with Excel.
