  • Thanks Bernard for sharing.
    IMHO Sentiment Analysis is embeded in the trading itself and can't be considered not even as a soft input (unluckily...). Stocktwits make humans think they can equal the automation (real time info vs real time trade). I think we are moving away from a commoditized fundamental analysis since available information grows much faster than our ressources as individuals to crunch it seamlessly.
