ges, RSI has served me well here as one indicator, and the historical correlations I have looked at since $1 when I first got in are spot on. Calling it pump and dump for traders is disingenuous at best and smells like someone talking their book or love affair with a stock or individual investment strategy. But like I mentioned before, there are lots of technical indicators, none of them are right or wrong and none of them are always right or predictable for ones own objectives.
Equal and opposite reactions, or every winner has a loser on the other side of the trade in the market. Making money is the first rule in the stock market, keeping it is the 2nd. Being nice about your own style vs someone else is a rule too, I call it common courtesy.
