- The Nifty 50 has fallen over 10% from its January peak, with India VIX spiking and FIIs net sellers for months amid West Asia escalation, surging crude, and Strait of Hormuz threat.
- Sensex data over 46 years shows 10%+ intra-year drops occurred in roughly 90% of years, yet the index ended positive about 80% of the time, growing from a base of 100 in 1979 to over 85,000 in 2024.
- Historical crashes all recovered: the 1992 Harshad Mehta scam saw the Sensex fall 40%+ and recover 82% by 1996; 2003 ended up 74% from ~3,000; 2008's fall from 21,000 to ~8,000 more than doubled by late 2010; March 2020's 38% Nifty plunge rallied 130%+ by late 2021.
- March 2020 exit cost: an investor who sold near the bottom and waited even six months to re-enter missed roughly 50% of the rebound — translating to nearly ₹50 lakh lost on a ₹1 crore equity portfolio.
- The 2024 pattern repeated: the largest equity mutual fund outflows came just before the market's strongest rally of the year.
- Sandeep Jethwani (co-founder, Dezerv) frames the correction through Kahneman-Tversky loss aversion (losses felt ~2x as intensely as gains) and argues the real danger is mistaking a cyclical shock — FII outflows, oil spike — for permanent structural damage.
Why it matters: The author frames the Nifty's 10%+ drop as cyclical, not structural: over 46 years, the Sensex has seen 10%+ intra-year falls in roughly 90% of years while ending positive about 80% of the time. His concrete cost-of-exit example: a March 2020 seller who waited six months to re-enter lost ~50% of the rebound — about ₹50 lakh on a ₹1 crore portfolio.
