I have read that Warren Buffett wrote a lot of uncovered Puts on all the world's major stock indexes with an expiration of like 15 years or so. I thought the longest Call/Puts were like 1-2 years! 15 years??? Is there a way to find out exactly which indexes and strikes? And the premium he got? I am just curious what Implied Volatility he got??? Also I read today on Bloomberg that he is also short Credit Defualt Swaps. Things which contributed to the collapse last year! So which companies bonds did he sell protection for? I hope not Lehman Where can I find all this info? Thanks!
