Because FV is up almost 60, which is 100% more than SPX change. Further, while FV and SPX tend to move in the same direction, FV rarely moves this convincingly in the same direction. It may be a "weak signal." http://gotepoem.wordpress.com/2011/03/19/weak-signals-or-weak-theory-of-observation/
You are cherry picking data, FV was 1056 on Friday ("10-07-11 09:52 AM - FV 1056.75") - so it's only 40 points higher now....big deal.
As I said before.... We have rallied 110 pts from the bottom in 5 days. So what have we learnt here?: 1. Well, see the quote. You don't need to time correctly in big volatility, just be patient. 2. Your FV is worthless, because it didn't predict this move. 3. Your previous nice gain was a question of luck, not your skill or good strategy. Also see #1 again. 4. You political/economical posts are worthless. Although your price level predictions were very good. So maybe you should just stick to that...
With nearly 100 handles of edge to FV and 295 to CFV, can't go wrong being short, 50+ handles of heat notwithstanding....
