Nifty 50 Anomaly Scan 2026-07-23 | Top Stocks by News Sentiment & Weighted Score — Shakti Tiwari

Nifty 50 anomaly scan

By Shakti Tiwari — Nifty Option Trader, NISM-Certified (Series-XII), Research Analyst & XGBoost Expert. Research only, not SEBI-registered advice.

Published: 23 Jul 2026, 10:38 AM IST | Market data as of: 23 Jul 2026, 10:38 AM IST (delayed/EOD (Yahoo Finance)) | Source: Yahoo Finance (prices) + Google News RSS (sentiment).

As of 23 Jul 2026, 10:38 AM IST, Nifty 50 is at 23,972 and Bitcoin near $65,577. This scan ranks Nifty 50 constituents by a transparent weighted anomaly score (news negative-sentiment %, volume, sentiment momentum) refreshed live.

Method note: The score is a documented weighted heuristic (0.5·neg% + 0.3·vol + 0.2·shock). It is not a trained XGBoost model and not a price prediction. It flags attention zones only.

Top Anomaly Rankings (Live)

Rank Stock Price ₹ Neg % News Vol Score
1 AXISBANK 1,235 100% 6 68.0
2 HDFCBANK 747 67% 6 51.3
3 ICICIBANK 1,442 67% 6 51.3
4 TCS 2,213 33% 6 34.7
5 SBIN 1,021 33% 6 34.7
6 RELIANCE 1,285 17% 6 26.3
7 INFY 1,043 17% 6 26.3
8 ITC 281 17% 6 26.3
9 TATAMOTORS n/a 17% 6 26.3
10 M&M 3,247 0% 6 18.0

Data gap: one or more constituents returned no price from the feed at fetch time (marked **n/a); its score reflects news signals only.

What The Score Means

  • Neg % = share of recent news flagged negative by our sentiment model.
  • News Vol = number of fresh headlines (momentum proxy).
  • XGBoost-style score = weighted blend (0.5·neg% + 0.3·vol + 0.2·shock). Higher = bigger anomaly.

How To Use It

Pair anomalies with option-chain OI + max pain before any trade. High negative score = caution/contrarian zone, not a blind sell.
