🎯 In 30 seconds: A bull market is a long rise. A correction is a fall of about 10% to 20% from a peak. A bear market is a fall of 20% or more. A crash is a fall that happens very fast. India has had several bear markets: after the 1992 securities scam, the 2000 to 2001 tech bust, 2008 (when the Sensex lost more than 60%) and the March 2020 COVID crash. Every one so far was eventually recovered, but some took years, and individual shares often never came back. The math is unkind: a 50% fall needs a 100% rise just to get back to where you were.
The words, defined
None of these terms has a legal definition. They are market conventions, used loosely in the news. These are the common meanings, measured from the highest closing level.
| Term | Rough meaning |
|---|---|
| Bull market | A long period of rising prices, often lasting years |
| Pullback or dip | A fall of less than 10%. Happens most years, often several times. |
| Correction | A fall of 10% to 20% from a recent peak |
| Bear market | A fall of 20% or more from a peak, usually lasting months |
| Crash | A very fast fall over days or weeks, often with single-day drops of 5% or more |
| Drawdown | Any fall from a peak, measured in percent. The word traders use for their own accounts too. |
The names come from how the animals attack: a bull thrusts its horns up, a bear swipes its paws down. That is the whole story behind them.
The big Indian declines
These figures come from news reports and exchange data at the time. Different sources use closing or intraday levels, so treat them as approximate.
| Episode | Index | From | To | Fall |
|---|---|---|---|---|
| 1992 securities scam | Sensex | about 4,467 (April 1992) | about 2,500 to 2,600 (August 1992) | more than 40% |
| 2000 to 2001 tech bust | Sensex | above 6,000 (February 2000) | about 2,600 (2001) | more than 55% |
| 2008 global financial crisis | Sensex | 21,206 intraday (10 January 2008) | below 8,000 (October 2008) | more than 60% |
| 2020 COVID crash | Nifty 50 | 12,362 close (14 January 2020) | 7,610 close (23 March 2020) | about 38% |
| 2024 to 2025 correction | Nifty 50 | 26,216 close (26 September 2024) | 22,083 close (4 March 2025) | about 16% |
| 2026 West Asia sell-off | Nifty 50 | 26,329 close (2 January 2026) | 22,331 close (30 March 2026) | about 15% by end of March |
What happened in each
1992: the securities scam. Between April 1991 and April 1992 the Sensex more than tripled, fuelled partly by money illegally diverted from the banking system into shares. When the scheme was exposed in April 1992, the index fell 12.8% in a single day and kept sliding for months. Lesson: a rise built on borrowed or stolen money can reverse very fast.
2000 to 2001: the tech bust. Indian technology and media shares soared with the global dot-com boom, and the Sensex crossed 6,000 for the first time in February 2000. When the global bubble burst, those shares collapsed. Many of the hottest stocks of 1999 never recovered.
2008: the global financial crisis. After a five-year boom, the Sensex peaked in January 2008. Foreign investors pulled money out of emerging markets as the US banking crisis spread, and by October the index had lost more than 60%. It took years to regain the January 2008 peak.
2020: COVID. As the pandemic spread and India announced a lockdown, the Nifty fell about 38% in roughly two months. On 23 March 2020 the Sensex fell 3,934 points, about 13%, its biggest one-day fall. Then came one of the fastest recoveries on record: the Nifty was back above its January 2020 high by November 2020.
2024 to 2025: a correction, not a bear market. The Nifty peaked in late September 2024 and fell about 16% by early March 2025, short of the 20% bear market line. It then recovered and made a new record close on 2 January 2026.
2026: the West Asia war. Fighting in West Asia began on 28 February 2026. Oil prices jumped, the rupee hit record lows against the dollar, and foreign investors sold heavily. The Nifty fell more than 11% in March 2026 alone, the worst month since March 2020, and closed on 30 March about 15% below its January record. How this episode ends was not settled when this chapter was written. Check current levels on niftyindices.com rather than relying on this paragraph.
The patterns worth remembering
- Small and mid caps tend to fall harder. Smaller, thinly traded companies usually swing more than the Nifty 50 in both directions. You will check this yourself in the exercise below.
- Foreign money moves fast. Big Indian falls usually come with heavy selling by foreign portfolio investors.
- Recoveries are uneven. The index recovering does not mean your shares did. The companies that led the previous boom are often not the ones that lead the next.
- Crashes arrive with a story. Every one had a reason that seemed obvious afterwards. Very few people timed the top and the bottom both.
Circuit breakers: the market's emergency brake
When the Nifty 50 or the Sensex moves 10%, 15% or 20% in a day, either way, trading across all Indian exchanges is halted for a set time under SEBI's market-wide circuit breaker rules. The halt depends on the size of the move and the time of day: a 10% move before 1 pm stops trading for an hour, and a 20% move stops it for the rest of the day. The trigger levels are recalculated daily from the previous close.
On 23 March 2020 the opening fall triggered such a halt. A halt gives people time to think. It does not stop prices from falling further when trading resumes. Stock-level price bands and the detail of these rules are in The rules every Indian trader runs into.
The math of getting back
Losses and gains are not symmetric. After a fall, you need a bigger percentage gain to get back to where you started, because you are gaining on a smaller base.
| Fall | ₹1,00,000 becomes | Gain needed to get back |
|---|---|---|
| -10% | ₹90,000 | +11.1% |
| -20% | ₹80,000 | +25% |
| -38% (like 2020) | ₹62,000 | +61% |
| -50% | ₹50,000 | +100% |
| -60% (like 2008) | ₹40,000 | +150% |
| -90% | ₹10,000 | +900% |
The formula: gain needed = fall ÷ (1 - fall). This one table is the reason risk management comes before everything else in trading. Risk comes first builds on it.
What a bear market feels like
On a chart, a bear market is a line going down. Living through one is different:
- Your portfolio is red every time you open the app, for months.
- Every rally feels like the bottom, then fails. Bear markets often have sharp 5% to 10% bounces on the way down.
- News, WhatsApp groups and friends who were boasting in the boom go quiet, then gloomy. Predictions of much lower levels get attention.
- Selling feels like relief, and buying feels foolish. That is exactly why many people sell near the bottom and buy back after the recovery.
What this means for a trader
- Strategies that work in bull markets often fail in bear markets. Buying every dip works until the dip keeps going.
- Volatility rises. Daily moves get bigger, gaps at 9:15 am get bigger, and stop losses fill further away. Smaller positions keep the rupee risk the same.
- Cash is a position. Not trading is a valid choice when you have no edge.
- Long-term investors and traders want different things. A SIP investor buys more units cheaply in a bear market. A trader has to survive it. A plan for a young person shows how to keep both.
Try it
- On niftyindices.com, open historical data for the Nifty 50 and the Nifty Smallcap 250.
- Find the closing levels around 26 September 2024 and 4 March 2025 for both. Work out the percentage fall for each.
- Do the same for 14 January 2020 and 23 March 2020 for the Nifty 50.
- In a notebook, write how you think you would have felt holding ₹1 lakh of small caps through each fall, and what you would have done. Be honest.
- An index falls from 25,000 to 21,000. Is that a correction or a bear market? Answer: A correction. It is a 16% fall, less than 20%.
- Your ₹2,00,000 portfolio falls 50%. What gain do you need to get back to ₹2,00,000? Answer: 100%. You need ₹1,00,000 to double.
- Roughly how much did the Sensex fall from its January 2008 peak to October 2008? Answer: More than 60%.
- The Nifty falls 10% at 11 am. What happens? Answer: The market-wide circuit breaker halts trading on all exchanges for about an hour before trading resumes.
- Why do small caps usually fall more than the Nifty 50 in a correction? Answer: They are less liquid and often riskier businesses, so selling pushes their prices down further, and buyers step back faster.
