Thanks aramz, I'm watching with extreme interest this week in particular.
Recently when the Dubai debt standstill initially surfaced I thought that was going to be sufficient to send the markets into a tailspin, it did but only on a very short term basis. Having said that it was enough for me to open a longish dated (DEC 2010) 'bought put' option position on the XJO as at the time options volatility was at a very low level & thus meant options prices were cheaper than they are now with respect to the recent spike in the VIX.
I see it as an insurance policy I guess and for a while I must admit I was wondering whether I had over-reacted however looking at world markets now maybe not???
