Sensex: how long each fall of 20% or more took to heal

What we measured

For every day since July 1997 the Sensex's closing level was compared with the highest close reached before it. A fall is the stretch from one peak until the index closed above that peak again. We kept the eight falls that reached 20% or more at their worst. These are price-index figures, so dividends are not included.

The eight falls

The median is about 2.0 years from peak to recovery, but the range is wide. Three of the falls were over inside a year, and three took close to or more than three years. Depth did not set the length: the 2020 fall (−38.1%) healed in under a year, while the shallower 2010–2013 one (−27.5%) took three years.

The fall now under way

The Sensex's last record close was 85,836 on 26 September 2024. On 16 October 2026 it closed at 74,729, which is 12.9% below that level. The low so far in this fall was 71,593 on 8 October 2026, 16.6% below the peak. That is short of the 20% line, so it is not in the table above.

It is nonetheless just over two years old, which is already longer than three of the eight falls took in full (2004, 2006 and 2020). The index closed 2025 at 85,221, within 0.7% of the peak, so most of the slide has come in 2026.

What the table suggests, and what it does not

Recoveries were uneven. Compounded over the whole recovery period, the index earned nothing, but the experience of an investor depended on whether they put money in near the peak or near the low. The 2008 fall is the clearest case: an investor who bought at the January 2008 peak waited until November 2010, while one who bought at the March 2009 low was already well ahead by then.

Falls cluster around one-off shocks and long grinds. The short ones (2006, 2020) were sharp declines followed by quick rebounds. The long ones (2000–2003, 2010–2013) were extended phases of weak markets. The table cannot tell you which type a current fall is.

A peak is a single day. Measured from a high set in a narrow spike, recovery looks longer than measured from a slightly lower, broader level. That is a feature of how a "peak" is defined.

What it means for a SIP

The Sensex's history is not a plan, but it shows why a monthly investment is built to keep going when prices are below an earlier high. Our post on how long the Nifty 50 took to regain each peak runs the same test on the Nifty 50, and the one on how long a gold or silver peak took to regain runs the same test on metals, and the five-year SIP study from every start month shows what a steady investor earned from the Nifty 50 across these same falls.

None of this predicts how long the present fall will last or how deep it will go. It records how long the eight earlier ones did.
