Nifty 50 streaks since 1999: 14 up days in a row, 10 down

Counting runs of closes

A streak is a run of consecutive sessions in which the Nifty 50 closed higher (or lower) than the previous close. The database's price history for the index has 6,871 closes from 1 January 1999 to 19 October 2026, which makes 6,870 daily changes. Of those, 3,687 were up: 53.7%. A coin weighted that way would produce streaks too; the interesting question is how long the real ones have been.

(Method note: a session with an unchanged close counts as not-up. If the database is missing a trading day, the two sessions on either side of the gap are treated as consecutive.)

The longest winning runs

The record run, 14 sessions in August–September 2024, was one of the smallest in terms of gain: 4.73%. The 11-session run of September–October 2007 gained 15.93%, more than three times as much in fewer days.

The longest losing runs

The longest fall was just 10 sessions, and in 2025 it cost 3.82%. Two other nine-session losing runs exist besides the one shown. The nine-session slide of September 2001 cost 16.79%, over four times as much in one fewer day. The length of a streak says little about its size.

How rare are long runs?

Winning runs of six or more sessions happened 99 times; losing runs of six or more, 55 times. That is consistent with the 53.7% up-day rate: if each day is up with probability near 54%, runs of upward closes are naturally more frequent and longer. A run of 8 or more is rare enough to remember: 28 winning and 14 losing in nearly 28 years.

Where the index stands now

On 19 October 2026 the Nifty 50 closed at 22,888.95, down 1.11% from 16 October's 23,146.15, which had itself been a 0.65% gain on the 15 October close of 22,997.35. So the current streak is a single losing session. For perspective on the year, the 2026 year-to-date fall has been built from a mix of runs, not a single slide.

What to take from it

• Streak length is not size. The longest up-run gained less than half of a nine-day run in 1999 and less than a third of the 2007 run.
• Nothing here predicts the next close. After a run ends, the next session is up or down on its own merits; a table of past streaks cannot say which.
• Big falls are about size, not days. The deepest fall in every year since 1999 and the days moving more than 1% are better guides to the risk in a holding.
