Investing in the stock market can be a rewarding yet complex endeavor. One of the most effective ways to manage risk and enhance returns is through diversification. By spreading investments across various stock market sectors, investors can minimize exposure to any single industry’s downturn while capitalizing on growth opportunities in multiple areas. In this guide, we will explore key stock market sectors and how they contribute to a well-diversified portfolio.
