Sensex Weekly Expiry: 79,000 Resistance, PCR at 1.06 and Key Support Levels

The Sensex recovered from its early weakness on Thursday, November 5, 2026, as the index moved towards 78,800 during the morning trading session. With the weekly derivatives expiry underway, options positioning indicates a contest between Put participants defending lower strikes and Call participants building positions near 79,000.

The open interest snapshot placed Sensex at 78,722.59, while the subsequent PCR and Max Pain readings showed the index at 78,782.65.

At the time of the latest snapshot, the PCR stood at 1.0593 and Max Pain was located at 78,600. The difference between total Put and Call open interest remains relatively narrow, pointing towards a market where neither side has established overwhelming control.

Sensex Options Data Points Towards a Balanced Market

The overall open interest distribution provides an indication of how traders are positioned for the expiry.

Total Put open interest stood at 845.29 lakh, compared with Call open interest of 797.98 lakh. Put OI therefore exceeded Call OI by approximately 47.31 lakh.

The resulting PCR of 1.06 reflects a modest advantage for the Put side. However, the reading is not sufficiently elevated to suggest strong bullish positioning on its own.

The intraday trend also provides some perspective.

The PCR initially slipped below 0.90 before recovering sharply above 1.20 as the Sensex rebounded. Subsequently, the ratio eased towards 1.06, indicating that the improvement in positioning lost some momentum.

The index's recovery alongside the rise in PCR suggests that sentiment improved during the morning session, although the latest reading points to a more balanced derivatives structure.

Why 79,000 Could Be Difficult to Cross

One of the most noticeable features of the options chain is the concentration of Call open interest near 79,000.

The strike carries approximately 71 lakh in Call OI, making it the largest visible Call concentration in the available data.

The 79,500 strike follows with nearly 49 lakh, while 78,800 and 78,900 also carry considerable Call positions of around 33 lakh and 32 lakh, respectively.

These concentrations suggest that the Sensex may encounter resistance even before reaching 79,000.

Fresh positioning adds another dimension to this picture.

The Change in OI chart shows approximately 51 lakh in Call additions at 79,000, the highest visible increase among the Call strikes.

The 79,500 strike also recorded notable additions of approximately 35 lakh.

This concentration of new Call exposure indicates that the upper strikes are attracting considerable activity during the expiry session.

For the Sensex to extend its recovery, the 78,800–78,900 region becomes the first hurdle. A sustained move beyond 79,000, particularly if accompanied by Call unwinding, could open the possibility of further gains towards 79,200 and 79,500.

Until then, 79,000 remains an important level to monitor.

Put Positioning Builds a Support Structure Below 78,700

While Call OI is concentrated above the prevailing index level, the Put side shows substantial positioning across lower strikes.

The highest visible Put open interest is at 78,000, with approximately 57 lakh contracts in the chart's lakh-based OI units.

Another sizeable concentration is present at 78,500, where Put OI stands near 44 lakh.

The 78,700 and 78,600 strikes also show meaningful Put positions, establishing multiple potential support zones below the current market.

The significance of 78,600 increases because the same strike represents the latest Max Pain level.

As long as the Sensex holds above 78,700–78,600, the nearby Put concentrations could help limit downside pressure.

However, a decisive break below this area may shift attention towards 78,500 and 78,400.

If these levels fail to hold, 78,200 and eventually 78,000 could become relevant.

The 78,000 strike stands out as the broader support reference because of its relatively large outstanding Put positions.

Fresh OI Activity Reveals Where Traders Are Positioning

Changes in open interest during the session provide additional clues about the evolving derivatives structure.

The highest visible Put addition was recorded at 78,000, where OI increased by approximately 57 lakh.

The 78,500 strike witnessed nearly 44 lakh in fresh Put additions, while 78,700 also attracted substantial activity.

Additional Put positions appeared across 78,400 and 78,600, suggesting that lower strikes continued to attract interest.

On the Call side, the largest additions were concentrated at 79,000 and 79,500.

Interestingly, the Change in OI chart also shows reductions in Call positions at several strikes below the prevailing spot level, including 78,000.

Such reductions may reflect the closing of existing positions, although the available data does not establish whether individual participants were buyers or sellers.

Taken together, the changes suggest that positioning is increasingly concentrated around identifiable lower and upper boundaries.

The immediate range emerging from the data is 78,600–79,000, with a wider set of significant positions extending from 78,000 to 79,500.

Max Pain Shifts Higher as Sensex Recovers

Another important development during the morning session was the movement in Max Pain.

The indicator began near 77,000 before rising sharply towards 78,300. It subsequently climbed through 78,400 and 78,500, eventually reaching 78,600.

This upward movement occurred alongside the Sensex's recovery towards 78,783.

At the latest reading, the index was approximately 183 points above the Max Pain level.

Max Pain represents the theoretical expiry price at which aggregate option-holder payouts would be minimised, based on the outstanding options structure.

Although traders frequently monitor the indicator near expiry, it does not determine where the index will settle.

Changes in volatility, fresh positions and the unwinding of existing contracts can alter the level throughout the session.

Sensex Weekly Expiry Outlook: Levels to Watch

The latest derivatives data suggests that the Sensex enters the November 5 weekly expiry with a mildly supportive but largely balanced options structure.

The PCR of 1.06 indicates slightly higher Put positioning, while the substantial Call concentration at 79,000 could make further upside challenging.

On the upside, 78,800–78,900 forms the immediate resistance zone. A sustained move above 79,000 could shift attention towards 79,200 and subsequently 79,500.

On the downside, 78,700 is the first reference level, followed by the 78,600 Max Pain zone. A break below this area could expose the index to 78,500–78,400, while 78,000 remains the stronger lower Put base.

For the remainder of the expiry session, the 78,600–79,000 region is likely to remain important in determining short-term direction.

A move outside this zone, supported by corresponding changes in open interest, would provide a clearer indication of whether the morning recovery can continue or whether selling pressure could return.
