because of the disclosure today, they have been buying recently and just achieved over 10%.
Due to recent AFFY prices, my guess is that Blackrock is in for near $6.50 average per share. They did not buy in to make only 10% or the like. I suspect, like us, they feel AFFY could be a Home Run ( or zero ). They must like what they see. This will garner some needed attention for AFFY.
The move today so far is great IMHO. NO gap up, just steady buying with steady moves up. Fantastic!!!!
IMO, their avg price is way higher than $6.50. Nearly one third of their shares are older/higher, I believe. If so, they may have averaged down to 10-12 now depending on the prices of their prev. purchases. BR would not have put in another $15 mil in new money last week though unless they liked AFFY a lot. BR and astute investors got a deal at these prices, imo. GL.
VA, they were already a holder but it looks like they added around 2.5 mil shares triggerring the 13G. "Date of Event Apr. 29" but not much more info available from the 13.
My guess is they took some of the secondary shares at 5.90 plus additional open market shares following secondary in high fives and six's and triggered the 10% filing. Filings like this help shine down on the pps games before and after the secondary don't you think. Also, they know when the 13's come out the price will jump. The big boys like to get their bargains. It will be interesting to see if the brakes will be lifted now. Good luck.
