Larsca,
This was not a huge selloff, nor was it a tremendous SP reduction. Based on the pics of the cores, how could you even begin to suspect that the Big Boys got wind of something bad and backed out due to a leak. Your supposition is exactly that, supposition, and not based on anything other than whimsy. Without immediate news to follow,any stock of note takes shots, knocking down the SP to get a better entry price. Today NOT actually did better than I thought it might. I have read some of your posts before and I have found some of them strangely negative. I'm not sure of your intent.
