Abstract	The equity market provides investors with significant opportunities for wealth creation, but it also exposes them to various forms of risk arising from market volatility, economic fluctuations, and company-specific uncertainties. In this context, portfolio diversification has emerged as an important investment strategy aimed at reducing risk by spreading investments across multiple securities, sectors, and industries rather than concentrating funds in a single asset. The present study examines the impact of portfolio diversification in reducing risk in the equity market and evaluates its importance in improving portfolio stability and investment decision-making. The study is based entirely on secondary data collected from academic journals, published research papers, books, financial reports, and relevant financial literature to understand the relationship between diversification and risk reduction. The research further explores key concepts such as systematic risk, unsystematic risk, asset allocation, and portfolio management to provide a clearer understanding of how diversified portfolios perform in uncertain market conditions. In addition, theoretical support from Modern Portfolio Theory is considered to explain how combining different assets may help investors reduce avoidable risk while maintaining return potential. The findings indicate that portfolio diversification plays a significant role in reducing unsystematic risk by minimizing the impact of poor performance of individual securities and enhancing overall portfolio stability. However, diversification cannot completely eliminate systematic risk caused by broader market conditions. The study concludes that portfolio diversification remains an effective and practical approach for equity investors seeking to achieve a balance between risk and return while supporting long-term investment efficiency and informed financial decision-making.
