There has been pretty heavy buying, both on the stock and the money markets, to prop things up. The weird thing is that this allows Putin and his buddies to buy up large amounts of stock at a huge discount.
Plus they're actually able to ensure the rightfulness of their ownership in said stock, unlike other participants which can get expropriated should they decide it is in their interest [0]. Would also expect insiders won't be blissfully scamming a shareholder if said shareholder is the state (or a friend of).
