The "How Much" Factor: Your success as a trader has little to do with selecting the right investment or even having a great system. Instead, it has everything to do with the “how much” factor when you invest or trade. Investment professionals have called this factor “asset allocation” or “money management.” However, they failed to understand that the key aspect was “how much” to invest in any position. Others work so hard to get themselves a good system, but fail to realize that position sizing strategies are the key to getting what they really want. When you have a great trading system, it is certainly easier to meet your system objectives through your position sizing method; however, you still have a chance to meet your objectives and profit with an average system if you understand how to position size properly. Yes, your position sizing strategy is that important.For many years Dr. Tharp has specialized in helping traders and investors understand position sizing strategies and how to use them effectively.
