Discretionary Investment Management is a form of investment management in which buy and sell decisions are made by a portfolio manager or investment counselor for the client's account. The term "discretionary" refers to the fact that investment decisions are made at the portfolio manager's discretion. This type of management is often used by high-net-worth individuals, families, and institutions who want someone else to make all the buy and sell decisions so they don't have to worry about it.A discretionary investment manager typically has a great deal of experience in investing and knows what stocks, bonds, or other securities are good buys at any given time. They will also know when it's time to sell these investments in order to protect their clients' portfolios from market downturns. Because they have this knowledge and experience, discretionary managers can charge higher fees than some other types of money managers.Despite the higher fees charged by discretionary managers, many people feel that this type of service is worth it because they don't have to worry about making tough financial decision themselves. Additionally, having a professional manage your money can help you achieve your financial goals quicker than if you were trying to do it yourself.
