Keep asking but don't expect everyone to answer as you would like them to. Learning on a message board is sometimes better and cheaper than trial and error, but certainly not always right. I remember wondering why I didn't get my dividend on a stock and then learned about EX dates after I called my broker lol, felt like a dumas but never made the mistake again. Soooo who cares if we have a little fun, your question was answered.
I know how you feel. Truth is, you don't need to know all that much. I invested in Colgate - CL. Why? They are ROCK SOLID. What else do I need to know? I invested in McDonald's - MCD. Why? C'mon, McDonalds do a rocking business. Just drive by one at lunchtime. I invested in XHB - Home Builders. Why? Housing was obviously way down and, it's human nature - people want to buy houses! I could go on, point is - the portfolio I selected last year has kicked some major league a*&(! And I'm not a genius or anything. When I saw AAPL at $405 - I thought "this is insane!!!". So I bought! Just on my gut feeling. That and knowing how great AAPL products are. And that the P/E was ridiculously low. What else you need to know?
