Method and apparatus for enabling individual or smaller investors or others to create and manage a portfolio of securities or other assets or liabilities on a cost effective basis

摘要

An investor adjusts a risk-return characteristic of a portfolio of investments by using a graphical user interface to adjust a pointer on a screen up or down. In response, the computer system automatically recalculates the required mix of the portfolio's stocks. Trades are then sent to the system for execution to implement the adjusted portfolio. Thus, investors are afforded a simple click-of-a-mouse mechanism to adjust their entire portfolio to precisely the types of portfolio characteristics desired without having to know about the various interactions of securities with each other or the portfolio effects of changing one security or another or have any other knowledge.
