4 of every 100 trend rules we track vote up for the Nifty 500, which has returned −5.4% over three months and −3.7% over a year.
Of the seven measures that vote, one says up, four say down and two sit in between.
They disagree: the 10-month rule, Nifty Smallcap 250 is above its average, while the trend ensemble score, Nifty 500 is 4.

The evidence
Each measure against its own history, strongest first. The bar runs from the lowest reading to the highest; the shaded part is the middle half. A measure votes up at or above the 70th percentile of its history and down at or below the 30th, unless its note says otherwise. Primary measures count double.

The answer above weighs the broad market. Follow each family below for its own trend rankings, momentum, regime history and path-quality comparisons.
Trend readings as of 5 Oct 2026. Counts cover each complete tracked family; quality tables lead with representative indices and retain the alternatives. Overlapping indices are not independent votes or diversification exposures.
The Nifty 500's total return over three years, set to 100 at the start (log scale), and the average of its last ten month-ends, which the pre-registered 10-month rule uses: in when a month ends above the average, out when it ends below. Shaded months are those the rule was in. The rule is checked only at month-ends, so the price can cross the line in between without switching it.

27% of NSE's indices have the 10-month rule in, among the lowest shares since 2005
At each month-end, the share of NSE's indices (broad, sector, strategy and thematic, about 114 today) whose month-end is above their 10-month average. A broad uptrend has most indices in; a narrow one has a few. A year ago the share was 82%. The latest month is month to date.

Descriptive, not a test
Since 1996, when the ensemble score was in today's band (0–20), the Nifty 500's median return over the next three months was +4.3% (positive 64% of the time, about 52 independent periods) and over the next year +14.1% (about 20 independent periods). Across all bands the one-year medians ran from +7.8% to +14.1%. With this few independent periods the differences between bands are not a forecast.
Investing in the Nifty 500 only when the ensemble said up returned 13.8% a year from 1996, against 13.9% for holding throughout, before tax. Its worst fall was −33% against −67%. After allowing for the 84 variants tried, the edge over holding is not significant (deflated Sharpe 0.02; 0.95 is the bar). The ensemble did pass its robustness test: it was the least regrettable choice among the single rules.
The score did not improve forecasts of a 10% fall or of next month's volatility beyond trailing volatility, the US VIX and the 200-day rule (p = 0.77 for a 10% fall).
From 1995 the 10-month rule on the Nifty 500 returned 11.6% a year against 13.2% for holding, with a worst fall of −45% against −67%; after counting trials, the edge is not significant (deflated Sharpe 0.01).
