The big fund selling makes sense explaining the weakness over the last few weeks. I wonder WHY a major shareholder for an exntended period would re-evaluate their position size. It can't be liquidity issues i.e. they need to raise cash as there have to be easier/quicker ways to raise cash selling more liquid stocks.
Maybe a little housekeeping? Selling a stock that they have a loss in for tax reasons? Seems a little early for that though.
