"One interpretation would be that the individual investors are buying and the so call "smart" money are selling."

I was thinking the same, just reluctant to say it or think about it.

Another way to look at it could be these 100k bids are walls being put up both high and low in order to maintain a certain price range..

Anyone have access to see who'se buying and selling these huge lots?, that;s about thte only way to track if the smart money is coming or going.
