Sensex vs Nifty 50 — which to pick: Sensex has 30 stocks (smaller, more concentrated, slightly higher top-name weight); Nifty 50 has 50 stocks (broader sector exposure). Both share most major holdings (HDFC Bank, Reliance, ICICI, Infosys, TCS, ITC, L&T, HUL, Bharti Airtel, Bajaj Finance). Historical correlation > 0.99 — meaning their returns track within fractions of a percent. Nifty 50 is the more widely used benchmark in modern Indian investing (NSE handles ~95% of derivatives volume); Sensex retains marginally higher brand recognition with general public. Pick by lowest TER + AUM — don't overthink it.
Sensex historical returns: 5-year CAGR ~14-15%, 10-year CAGR ~12-14%, 20-year CAGR ~13-15%, since-inception (1979) CAGR ~14-15% (price returns; total returns ~1-2% higher with dividend reinvestment). Major drawdowns: 2008 GFC (~60%), 2020 COVID (~38%), 2022 (~17%) — all recovered within 1-3 years. The Sensex crossed 75,000 in 2024 and continues to make new highs as Indian corporate earnings compound. Past performance does not guarantee future returns.

STT-paid only. Use the ₹1.25 lakh exemption for annual tax harvesting. Sensex ETFs trading on BSE settle at T+1.
Sensex points are not directly comparable to other indices like S&P 500 because base values and methodologies differ. What matters is the percentage change. Historic milestones: 1,000 (1990), 10,000 (2006), 50,000 (2021), 75,000 (2024). Annualised return since 1979 has been ~14-15% in INR terms (price returns; total returns higher with dividends).
