Investing in the Sensex, India's benchmark stock index, has proven to be a lucrative endeavor for disciplined investors. An individual who invested ₹1 lakh annually from 2001 to 2025 would have seen their total investment of ₹25 lakh grow to approximately ₹1.54 crore, demonstrating the power of systematic investment plans (SIPs) and long-term compounding. Over the past 25 years, the Sensex has delivered an impressive cumulative return of over 2,500%, despite facing significant market shocks, including the global financial crisis in 2008 and the Eurozone crisis in 2011. Notably, even during the pandemic in 2020, the index managed to close with gains of around 16%. The long-term trajectory of the Sensex reflects resilience and growth, emphasizing that time spent in the market is more effective than attempting to time the market. However, investors are advised to choose their stocks wisely, as poor selections can lead to wealth erosion.
