However, it only takes one trader with a naive NLP approach to make "Ann Hathaway" news legitimate Berkshire Hathaway news. i.e., one dumbass with a big enough bankroll buying on Ann Hathaway news makes Ann Hathaway news relevant to the market.
I'm not ruling out malice, but wouldn't you say that naivete would be a fairly unlikely reason for this at a place with a big enough bankroll? I've met some hedge fund types and they may be many things, but they're not idiots.
