Before I attempt to elaborate on my answer to your question, be advised that I executed the following at 3:34pm: Sold 1 block at 27.67, and covered 100 July 30.00 calls at .80/contract to take some profits off of the table.
The reason I sold 400 depp in the money calls is because after today's breach of 27.50 (technical support of 6-months), testing lower levels appears to be imminent. I'm not sure how much lower at the moment. That said, I wanted my deep in the money calls to hedge me while I accumulate the stock without having to predict a bottom precisely. I plan oncovering or buying back those calls as the time value on the calls decays and/or as the stock trends lower to establish a new bottom.
