What is Portfolio?

A portfolio is the complete collection of investments you hold—stocks, bonds, ETFs, real estate, and more. A portfolio can contain a mix of stocks, bonds, cash, mutual funds, ETFs, real estate, and alternative investments like cryptocurrencies. The portfolio is the vehicle used to meet financial goals.

Portfolio design is guided by modern portfolio theory, which balances risk and reward based on an investor's risk tolerance, time horizon, and goals. The performance of a portfolio is evaluated as a whole, rather than focusing on the return of a single asset.

Managing a portfolio involves asset allocation (determining the percentage of the portfolio dedicated to different asset classes) and periodic rebalancing (adjusting the weight of assets as market fluctuations cause them to drift from target allocations) to maintain the desired risk profile.

PRACTICAL EXAMPLE

An investor's retirement portfolio is worth $100,000. It is allocated as 60% stocks ($60,000 in stock ETFs), 30% bonds ($30,000 in bond index funds), and 10% cash ($10,000 in a high-yield savings account) to achieve moderate growth.
