📰 News That Moved Markets

  • Honeywell Automation shares fell 2%, making it one of the top losers on the Nifty Midcap 150, signaling some sector-specific weakness.
  • Nifty 50 is on track for a fifth consecutive day of losses, reflecting cautious trader sentiment amid mixed market signals.
  • NBFC stocks remain attractive on dips as FY27 credit growth expectations stay strong, supporting select banking and finance names.

📈 Volume & Smart Money Signals

Among the ~200 actively traded F&O stocks, 130 saw volume surges exceeding 1.5 times their average, highlighting strong trading interest. Notably, stocks like Motilal Oswal and Oberoi Realty recorded volumes over 15 times their average. High delivery percentages in key stocks such as Dabur (76.9%), HDFC AMC (74.4%), Kotak Bank (73.9%), and Reliance (72.4%) suggest strong institutional participation and confidence.

🔮 Under the Hood: Market Structure

Today's market displayed a mixed bias with a variety of day types among F&O stocks: 47 showed a normal variation up day, while 64 experienced a normal variation down day. The NIFTY itself had a trend down day type, closing below the previous day's value range.

Opening price behavior was diverse: 106 stocks opened within the previous day's fair value zone (the price range where most trading occurred), while 40 opened below and 27 above it. There were 22 instances where price broke out above the first hour's range (open drive up) and 15 where it broke down.

Buying tails, indicating aggressive buying at the day's lows, appeared in 55 stocks, slightly outnumbering selling tails seen in 47 stocks. This suggests some underlying support despite the mixed overall trend.

The most-traded price level (Point of Control) and value area shifted lower for the NIFTY, confirming the downward trend. Single prints, representing rapid price moves with little trading, were more frequent on the upside (14) than downside (5), indicating some quick upward price attempts that failed to sustain.

⚡ F&O Highlights

Four stocks were in the F&O ban list today due to price movement limits: Bandhan Bank, LICI, Manappuram, and SAIL. Traders should exercise caution around these names.

📅 Upcoming Events

The next weekly F&O expiry is scheduled for 18 August 2026, with the monthly expiry following on 25 August 2026. No major corporate results or macroeconomic events are expected in the immediate days ahead.

🎯 Stocks to Watch Tomorrow

  • Motilal Oswal Financial Services – Strong volume and buying interest today could extend gains.
  • Inox Wind – Infrastructure sector leader with a solid buying tail and volume surge.
  • Oberoi Realty – Continued strength in Realty sector with high volume and positive price action.
