there have even been a few instances shown on HN where these algorithms picked stuff up from the internet and have run with it, i.e. placed real trades. I remember at least 2 instances of this recently, once where the story was fake and once where an earnings forecast(i think) was released on a site but they had not published the URL so the assumption was no one would see it. The bot made a significant sum on the second example.

  Many stories are deliberately faked to push the sentiment bots. Its a murky world.

  Fascinating - especially if the loop get closed and trading algorithms can generate short-lived tweets (Markov chains?) to disrupt their opponents sentiment analysis.
