I have got a sizeable portfolio of US stocks - mostly above 30bn market cap ones and I have written calls against most of them. I would like to hedge value of my portfolio and I was reading Murphy on this subject. It is quite complicated and I would like to take some simple approach. There are many experienced option traders on this site and I would much appreciate comments and guidance. If there are articles or some books , please give details as well. Thanks so much for help.
