it's late out here on the west coast and i don't have time to dig up more examples, but the link above should be enough to convince you that your posts are being studied and will in some way be gauged into a stock's price. many factors contribute to stock price and retail investors control very few of them if any, so think before you post, and dig thru the net to learn more about sentiment analysis, for your own good. control what you can, and that is what you say, how you say it, when you say it and what message are you sending over and above your actual words.
best,
