If you have ETFs or index tracking funds in your 401k you're going to buy it. In fact, you'll buy more of it than is going on sale. Since they only need to issue 5% of the stock for it to show up as a 20% market cap in the QQQ index and tracking funds own over 20% of the market, they pretty much have to buy all the shares.
