Portfolio Management Services (PMS) is an investment service that provides professional advice and management of a portfolio of securities, such as stocks, bonds, and mutual funds, for a fee. PMS services are typically offered by investment advisors, banks, and other financial institutions. The portfolio manager is responsible for selecting the appropriate investments, monitoring the performance of the portfolio, and making adjustments as needed. PMS services can be tailored to meet the individual needs of the investor, such as risk tolerance, investment goals, and time horizon.
