News may be good for the company, but good news doesn't pay you. Only the dividend (AA - 12 cents a year) and price action (traders buying and selling) pays.

This is the most common mistake I see among new traders. It's not your fault, you just don't know any other way, yet.

What price did you buy at, and what is your stop plan and/or target price to sell?

No stock will go up forever, eventually people will take some profits. Pullbacks are just part of market cycles. Before getting into a trade I have a plan based on the price action at that moment. Every stock can be different though. It could be a 5 minute plan or a 1 year plan. Nonetheless, having a plan will help take emotion out of the trade so you can focus on finding good entries and then let the plan work.
