I wonder who bought the 5% of News Corp from the prince?
Funny how no one is asking that, isn't it? "Why did the prince sell?" The better question is "why did someone else buy?"
Soros probably bought it all. Meet the new boss, same as the old boss.
When you sell your stock on the NYSE, you have no idea who is buying it. Your trader breaks it up into 1000-share lots, and pushes it out over a period of months.
