As of 12:50 PM, the Sensex had deepened its losses and was trading near the 76,400 mark. Earlier, the index had touched an intraday high of 76,726.66 before giving up its gains and slipping lower.
The retreat towards 76,400 indicates that selling pressure has strengthened during the afternoon session. The index is now trading around the revised maximum pain level of 76,400, making the 76,400 to 76,500 zone decisive for the remainder of the weekly expiry session.
Sensex PCR Drops Below One
The Put Call Ratio (PCR) for all expiries has declined from 1.09 in the morning update to 0.77, while the maximum pain level has shifted lower from 76,600 to 76,400.
A PCR below 1 indicates that call open interest now exceeds put open interest. The sharp decline suggests that the derivatives setup has turned more cautious as fresh call writing accelerated after the Sensex failed to sustain its early gains.
Sensex Put Support Remains at 76,000
On the put side, the 76,000 PE strike continues to have the largest overall put open interest concentration.
Unlike the morning session, no significant build-up has emerged near the current market level. This suggests that put writers continue to expect the Sensex to remain above 76,000 during the weekly expiry session. However, the support base is positioned well below the current market price, so a sustained fall below 76,400 could increase downside pressure towards 76,000.
Sensex Call Resistance Shifts Lower to 76,500
The more significant change has emerged on the call side. Earlier, the highest call open interest concentration was positioned at the 77,000 CE strike. It has now shifted to the 76,500 CE strike, which also has the largest overall call open interest concentration.
This indicates that call writers have moved their resistance base lower from 77,000 to 76,500 after the index failed to maintain its early strength. The shift reflects greater confidence among call writers that the Sensex may struggle to settle meaningfully above 76,500.
Sensex Weekly Expiry Outlook: 76,400–76,500 Zone Holds the Key
The latest positioning has created a tight expiry battle between put writers at 76,000 and call writers at 76,500. With maximum pain also placed at 76,400, the Sensex may remain confined around this zone unless either side begins to unwind aggressively.
A sustained move above 76,500 would place call writers under pressure and could trigger an advance towards 76,700, then 77,000. Conversely, a decisive break below 76,400 would weaken the immediate structure and could pull the index towards the stronger support near 76,000.
Compared with the morning update, the expiry setup has turned more cautious. Maximum pain has shifted lower to 76,400, while call resistance has moved down to 76,500. The index must reclaim and sustain above 76,500 to restore its positive momentum.

As of 10:40 AM, the BSE Sensex was trading at 76,603, down 0.20% for the session, as traders managed positions carefully ahead of the Sensex weekly expiry.
The index opened at 76,515.10 and touched an intraday high of 76,680.07 before slipping to a low of 76,344.67, reflecting mild selling pressure through the early session. It was seen trading within the previous session's range of 76,641.19 to 77,384.95, where the index had closed at 76,755.05, down 0.92%. A sustained move above 76,680 would be needed to signal any meaningful recovery, while continued weakness below 76,600 could expose the index to the next support zone.
