Sensex Weekly Expiry Afternoon Update: PCR at 1.38 as Index Holds Above 74,500

The BSE Sensex continued to trade with a positive bias during the afternoon session of the weekly expiry on September 17, 2026, holding above the key 74,500 zone after a firm opening.

At around 12:20 PM, the index was trading at 74,521.96, higher by 185.51 points or 0.25%. The index has remained stable compared with the morning session, although it has eased slightly from the day's high. The options setup has seen some adjustment, with the PCR moderating to 1.38 from 1.50 in the morning, while the maximum pain level remains unchanged at 74,500.

Expiry Positioning Remains Favourable for Put Writers

The PCR at 1.38 indicates that Put open interest remains higher than Call open interest, although the ratio has declined from the morning level.

The Sensex is currently trading close to the maximum pain strike of 74,500, making this level important for the remainder of the expiry session. The options data suggests that traders continue to maintain a support base below the current market level, while resistance remains placed at higher strikes.

Call Activity Builds Resistance Above Current Levels

The Call side continues to show concentration at higher strikes, with the highest open interest placed at 75,000 and 74,500.

Fresh Call additions have emerged near 75,000 and 74,800, indicating that traders are actively positioning around these levels. The 75,000 mark remains an important hurdle as the index approaches the upper end of the current expiry range.

A move above 75,000 could force adjustments from Call writers and improve the upside momentum. However, until the index clears this zone decisively, supply pressure may continue to limit gains.

Put Positions Provide Cushion Near 74,000–74,300

On the Put side, open interest remains concentrated at 74,000 and 74,300 strikes, highlighting the support zone for the index. Fresh Put additions are visible at 74,000 and 74,400, showing continued positioning below the current market price.

The 74,300–74,000 area becomes important for the remaining session. Holding above this zone would keep the expiry structure stable, while a break below 74,000 could indicate weakening support and increase volatility.

Sensex Expiry Outlook: 74,500 Decides the Next Move

The afternoon expiry setup remains centred around the 74,500 zone, with the index trading close to the maximum pain level.

The options structure shows support developing around 74,000–74,300, while Call positioning near 74,500–75,000 may restrict immediate upside. The market is currently balancing between these two zones. A sustained move above 75,000 could strengthen buying momentum and push the index towards higher levels. On the other hand, a decline below 74,300 may weaken the current setup and bring sellers back into control.

With PCR still above 1 and the index holding near the key expiry strike, Sensex is likely to remain range-bound unless there is a decisive move beyond the immediate support or resistance levels.
