A model portfolio in investing refers to a pre-designed investment portfolio that is intended to serve as a template or guide for investors.

 It is typically created by investment professionals or financial advisors and is designed to achieve specific investment goals, such as growth, income, or capital preservation.

A model portfolio typically includes a mix of different asset classes, such as stocks, bonds, and alternative investments, in proportions that are intended to balance risk and return.

 The specific composition of a model portfolio can vary depending on the investor's risk tolerance, investment horizon, and other factors.

Model portfolios can be useful for individual investors who may not have the time, expertise, or resources to build and manage their own diversified investment portfolio. 

By following a pre-designed model portfolio, investors can potentially benefit from the expertise and research of the professionals who created it.

However, it's important to note that model portfolios are not one-size-fits-all solutions, and investors should carefully consider their own unique financial situation and investment goals before adopting a model portfolio.

 Additionally, model portfolios may need to be adjusted over time as market conditions and an investor's needs change.
