Most charts show volume by the minute or 5 minute intervals or you can check Level II which I also have.
Looks like it was enough (for the moment) to kick some of the traders, algos, bots into gear and do a little more selling after all. Kudos to that fund.
Now its in buy on rumor sell on the news. Selling on the good quarter and raise but this is about 90% algo/tech traders popping it around.
I added to my position which I own around half the current price. Next few years look pretty good for Celgene. I won't sweat 5, 10 or 20 bucks on the share price. This stock is headed over 200 in next 1.5 to 3 years. Probably closer to the 1.5. That is about a 65% return over these periods. On an Annualized basis it should be a formidable market beater
