You're better off doing your own research, doing a shitload of reading, understanding trends, studying charts looking for recognizable patterns, etc. If you want to buy and hold you can pretty much pick any name brand stock and you'll make money down the road. If you're looking to make quick money, it's a lot harder to call it right. I'm 100% self-taught about the stock market and I'm doing pretty well, but it's taken some time to get it right. If you're new to the market and looking for quick profits, I suggest playing a fantasy stock market for a while to test your strategies and hunches without the risk of losing any money.
I recently started putting CNBC on in the background when I'm home during the day, just to keep abreast of any breaking news, to listen to any knowledgeable guests that might be on, get some clues as to the psychology that's moving the markets, etc. I look into some of the tips I hear about, use them as a jumping off point to do my own research, but never take the advice I hear blindly.
That said, Cramer has an extremely poor track record and subscribes to the "dartboard" theory of picking stocks IMO. I change the channel whenever he's on. He does offer up a lot of stock tips, and as DQ's links point out, he's notorious for giving bad advice. John Stewart's famous line: "If I followed Cramer's advice I'd have $1,000,000........providing I started out with $100,000,000."
