Bull markets, bear markets, corrections — what these terms actually mean

You hear these terms constantly but the definitions matter. Here is exactly what each means, how long they last, and why the right response is almost always the same.

Key takeaways
Bull market = sustained 20%+ rise; bear market = sustained 20%+ fall
A correction (10–20% fall) is normal and healthy — not the same as a bear market
Average bull market lasts 5+ years and gains 150%+; bear markets last ~11 months
Missing the 10 best trading days in a decade can cut returns by 50%
Every bear market in history has been followed by a new bull market high

The asymmetry that matters
Average US bull market (data since 1928): • Duration: 5.5 years • Gain: +181% Average bear market: • Duration: 11 months • Loss: −38% The implication: markets spend far more time going up than going down. Every bear market has been temporary. Every bull market has eventually surpassed the previous high. India's data is shorter but consistent: every Nifty bear market has been followed by new all-time highs.

⚠️
The cost of missing the best days
₹1 lakh invested in Nifty 50 from Jan 2003 to Dec 2023 (20 years): • Fully invested throughout: ~₹15.8 lakh (CAGR ~15%) • Miss the 10 best trading days: ~₹7.2 lakh • Miss the 20 best trading days: ~₹4.1 lakh • Miss the 30 best trading days: ~₹2.5 lakh The 10 best trading days almost always happen in the middle of or immediately after the worst periods — when most investors who sold are too scared to re-enter.
Correction vs bear market — how to respond differently
Correction (10–20% fall)
Very common — happens roughly every 1–2 years
Often over quickly — weeks to a few months
Best response: do nothing, SIP continues
Optional: deploy any surplus cash as lumpsum
Worst response: sell, planning to 'buy back lower'
Bear market (20%+ fall)
Less frequent — major bear every 5–8 years in India
Lasts months to a year+
Best response: do nothing, SIP continues, possibly increase
Historical fact: all Indian bear markets recovered fully
Worst response: sell everything, wait for 'all clear'
