A Zero-Investment Portfolio refers to an investment portfolio with a total value of zero, meaning that the value of its assets is equal to the value of its liabilities. This can occur when an individual has invested all of their available funds into a portfolio and has no additional cash or investments outside of that portfolio.A zero-investment portfolio is often used by individuals who are just starting to invest and want to build a portfolio from scratch. By starting with a zero-investment portfolio, individuals can focus on allocating their funds into different asset classes and diversifying their investments.Over time, as they make contributions to the portfolio, its value will increase, and they can adjust their investment allocation as their financial goals and risk tolerance change.It's important to note that a zero-investment portfolio is not a long-term investment strategy, and individuals should have a plan for contributing to the portfolio over time.Additionally, a zero-investment portfolio is subject to various risks, including market risk, credit risk, and inflation risk. As with any investment, it's important to thoroughly understand the risks and to consult with a financial advisor before investing in a zero-investment portfolio or any other investment.
