Why the Sensex fell

Heavyweights weak, broad market steady
Over 150 stocks hit 52-week lows, Avenue Supermarts, HUL, NTPC and Reliance Industries among them, according to Moneycontrol. The broader market told a different story. The Nifty Smallcap index gained 1.4% and the Midcap index closed flat, while media, auto, realty and pharma all ended higher. More on why smallcap stocks rose today.
Stock-specific moves
- Avenue Supermarts lost more than 4% after its Q2 numbers. Our DMart Q2 results post breaks them down.
- ideaForge Technology rose 10% after signing a ₹151 crore loan agreement with the Technology Development Board (Moneycontrol).
- Lenskart Solutions slipped 4% after 2.93 crore shares, or 1.67% of its equity, changed hands in block deals (Moneycontrol).
What it means for investors
Going from a 400-point gain at the open to a 548-point loss by the close tells you how shaky sentiment is right now. Rallies are getting sold into while foreign investors keep selling. After the bell, retail inflation came in at a 23-month high of 5.54%; read about retail inflation in September 2026. That number, along with Q2 results, will set the tone for the next few sessions.
