Not sure if they really did. At 9/30, Yahoo is showing BR Fund Advisors at 1,775,282 shares held. This matches the total listed in the Nasdaq holdings link you referenced. At 9/30, Yahoo shows BR Institutional Trust Company at 1,545,286 shares held. The Nasdaq link shows BR Investment Management LLC at 393,102 shares. All these Blackrock entities in total would be about 3.7M shares. Looks like they increased by about 200k shares if my math is right. I guess we need till we see the 12/31 holdings schedule in total. That should happen by Feb 15th I think. Insitutions have 45 days to report holdings I think. The BR info on the Nasdaq holdings link is old. Still says 9/30 holdings.
