I have no problem with contrary posts , if there is substance behind them. but, you should sell because i did or because i don't like this stock is not substance. someone else's circumstances or risk tolerance is not the same is mine. News, PR, analyst up or down grades, etc. may be a reason to buy or sell , some random stranger pops up and says i don't like it , eh, whatever.
