A broad portfolio refers to a diverse range of investments or assets that are held by an individual, company or institution. The term 'portfolio' is used to describe all the different financial instruments such as stocks, bonds, mutual funds, real estate and other securities owned by someone. A broad portfolio implies having a wide variety of these holdings spread across various industries, geographies, asset classes or investment styles in order to reduce risk and maximize potential returns. By holding a diverse range of assets, an individual can minimize the impact of any one particular investment on their overall financial position while also taking advantage of opportunities for growth that may arise from different sectors of the economy. In summary, having a broad portfolio means being well-diversified and not putting all your eggs in one basket, which helps to reduce risk and improve chances of better returns over time.
