Stocks

I really want to learn about stocks. I know its a high risk investment but it's also yields a huge amount of earnings if you know how to play. I know with the global economic crisis still creating waves one should be a little bit cautious. But I also happen to remember someone said that when the economy is on a dip and everybody does not want to risk, prices of stocks are at low so its time to buy because eventually the stocks will go up and you would be on top. But of course, as a newbie I might as well used Power Option to help me in my decisions with stock. Also, I have to learn more about covered calls to protect my investments just in case I have decided to take the plunge in stock trading.
