Series 7

I’ve been looking to invest in the stock market lately. I’ve always taken an interest in it, I just figured now would be the perfect time to take the plunge and put my money on the line with it. I’ve been researching brokers, and I think I am going to go with one who is licensed in Series 7. Series 7 licensed brokers seem to be more knowledgeable as they have to do a lot to get licensed in Series 7. I don’t feel comfortable giving my money to someone who isn’t knowledgeable in the field, I mean it is my money and I want it to be doubled, or more, so why would I give it to someone less experienced right?
