Paul Tudor Jones is one of the most successful global macro fund managers out there. He manages in excess of $17 billion at his hedge fund, Tudor Investment Corp. Although these quotes are older (taken from around 2000), they are very generalized and still serve as great advice for any investor/trader.
"I'd say that my investment philosophy is that I don't take a lot of risk, I look for opportunities with tremendously skewed reward-risk opportunities. Don't ever let them get into your pocket - that means there's no reason to leverage substantially. There's no reason to take substantial amounts of financial risk ever, because you should always be able to find something where you can skew the reward risk relationship so greatly in your favor that you can take a variety of small investments with great reward risk opportunities that should give you minimum draw down pain and maximum upside opportunities."
"And then at the end of the day, the most important thing is how good are you at risk control. Ninety-percent of any great trader is going to be the risk control."
