Glen's Verdict

Former hedge fund manager, current index fund enthusiast

Nifty 50, but honestly it barely matters. Over the last 20 years, the Nifty 50 and Sensex have had a correlation above 0.98 — they move almost identically. The Nifty 50 wins on breadth (50 vs 30 stocks) and product availability (more ETFs and index funds track it). The expense ratio on UTI Nifty 50 Index Fund is 0.18%, while SBI Sensex Index Fund charges 0.10% — both are dirt cheap. If you're starting fresh, go Nifty 50. If you're already in a Sensex fund, don't bother switching. The real decision isn't Nifty vs Sensex — it's whether you're investing consistently via SIP. That matters 100x more than which index you pick.
