Always a bigger whale out there with the ability to exert pressure...
I guess it makes sense, wondering what Citadel will do with it...
It would be like if you needed to acquire 100M shares of Apple -- usually a broker will fill that large of an order from several sources OR if some fund has the full liquidity, it can be filled from that single position (and thus acquiring the fund's portfolio position). Now repeat this for their ENTIRE portfolio.
