blackrock sells down more, page-6

Last announcement reflected position as at 16 April.
Why did they not sell NCM like everyone else around that time until end of June between say 14 and 17 dollars and only now announcing to the market.What would prevent them from doing it ? Why were they selling them recently at 10 and 11 dollars as is suggested by some posts?
Maybe they announce it now so they can get the shorts all excited and they then have the chance to buy back some of the position?
Who knows... time will tell but timing of announcement is curious...
Large volumes going up .... light volumes going down ...who cares??
Good luck all!
