Portfolio investments are investments in the form of a group (portfolio) of assets, including transactions in equity, securities, such as common stock, and debt securities, such as banknotes, bonds, and debentures.

Portfolio investment covers a range of securities, such as stocks and bonds, as well as other types of investment vehicles. A diversified portfolio helps spread the risk of possible loss because of below-expectations performance of one or a few of them.

An aggressive investment strategy typically refers to a style of portfolio management that attempts to maximize returns by taking a relatively higher degree of risk.

A defensive investment strategy entails regular portfolio rebalancing to maintain one’s intended asset allocation; buying high-quality, short-maturity bonds and blue-chip stocks; diversifying across both sectors and countries; placing stop loss orders; and holding cash and cash equivalents in down markets.

Hybrid funds offer investors a diversified portfolio. The term hybrid indicates that the fund strategy includes investment in multiple asset classes… Hybrid funds are commonly known as asset allocation funds.
