A portfolio management service (PMS) is a tool provided by a portfolio manager to achieve a desired return for a desired level of risk. An investment portfolio may consist of stocks, fixed income instruments, commodities, real estate, other structured products and cash.

A portfolio manager is a licensed investment professional who specializes in analyzing an investor’s investment objectives and has extensive knowledge of various market instruments. Unlike a layperson, the portfolio manager is in a better position to make informed decisions when it comes to investing in stocks.
