Block Trades-
Don't mean to confuse the issue, but if 100+k trades are considered institutional, I'm pretty sure there were a lot of individuals out there(and some on this board) that could account for some(or most) of that trade.
So, from my way of looking at it, a lot of that buying may have been relatively rich individuals rather than institutions.
However, if accurate, your data at least suggests that institutions weren't selling in any volume, which is valuable and encouraging to know.
Thanks for the post.
