Portfolio Management Services (PMS) is an investment portfolio in stocks, fixed income, debt, cash, structured products and other individual securities, managed by a professional money manager that can potentially be tailored to meet specific investment objectives. When you invest in PMS, you own individual securities unlike a mutual fund investor, who owns units of the fund. You have the freedom and flexibility to tailor your portfolio to address personal preferences and financial goals. Although portfolio managers may oversee hundreds of portfolios, your account may be unique.
