Every institution manipulates every stock on the market - going back to some basic theory people generally talk about a market trending in phases representing accumulation, public participation and distribution followed by reaccumulation provided fundamentals remain constant.

Overall this helps bring the mean average for their holding down significantly, after which they can sell again after the inevitable public participation phase
