Today was by far the largest increase (64.22%) in the VIX since 1990, the furthest Bloomberg lets us download prices. Earlier in the day we noted the breakout of the 10 to 12.5 range. See the chart below for where the volatility index closed (18.31).
If you look at the chart, it looks like the VIX is susceptible to sharp upmoves after periods of quiet/consolidation. In contrast, there are no equally sharp downmoves in the VIX from periods of stability. This makes sense when we think about risk in society in general. In our day to day lives, when things are just humming along, we are prone to sudden risk 'scares', but not the converse.
I wonder if the assymmetric profile is accurately reflected in VIX options pricing? I'm sure it would be, but if not, then the insurance may be being routinely underpriced.

Making money in stock market is always a difficult task. Every person had a problem of involving risk of loss. Some had profits also no doubt. But now with First Hour Trading buying and selling stocks has become easy. I saw a video at http://www.youtube.com/watch?v=BJv17zWzp6o where Manny Backus shows us how one of his First Hour Trading members uses the system to generate profits at will in the stock market. After watching the video my friend joined the first hour trading and has been making regular profits.

Short volatility strateegies must have been killed yesterday. I'll be interested to see February's numbers for LJM Partners and similar funds.
