How to tell if a stock will go up or down?
That's all I want to learn for now. I know you can't be 100% but I don't want to Specifically, how do you know whether a stock will go up or down?

My example of how I would tell is, facebook has been trending upwards. Intraday, intraweek, and intramonth.
I also pulled up bollinger bands and intraday it appears to be closer to the red band meaning oversold.
SO I ASSUME IT WILL GO UP TOMORROW.

How do you guys decide whether a specific stock will go up or down, strategically.
