Guys
I've been reading your threads for about a week. I am new to investing and bought in siri at .11. I would like to trade up and buy back low to increase my overall position. This morning in premarket the stock was up 27% to .55. I couldn't find any news for the upswing, but I am afraid I will make a mistake and lessen my position. Now it looks like I missed an opportunity. How can I tell when I should sell and then re-buy. Some of you smart guys help me please.
