Sensex Weekly Expiry Outlook: Slips Below 72,000; Can 71,500 Hold?

Selling pressure intensified on Thursday's weekly expiry as the Sensex breached the psychological 72,000 level and extended its decline to more than 1,050 points. The benchmark index slipped below 71,600, trading close to its intraday low as bears maintained control of the session. Meanwhile, India VIX climbed 9.5% to cross the 15 mark, indicating increased uncertainty and the possibility of sharp price movements during the remaining trading hours.

Options Data Reflects Growing Bearish Pressure

The deterioration in market sentiment was also visible in the derivatives segment, where the Put-Call Ratio (PCR) declined steadily as the session progressed.

Earlier in the day, the PCR stood at 0.84, but by approximately 1:50 PM, it had fallen to 0.65. The decline indicates that Call open interest had become increasingly dominant relative to Put open interest, reflecting a bearish tilt in market positioning.

Another notable development was the sharp downward revision in the Max Pain level. Initially positioned at 72,300, Max Pain moved down to 71,700, marking a substantial shift of 600 points.

Such a large adjustment during the trading session indicates that options positions were being repositioned at lower strike prices as Sensex continued to decline. With the index under pressure and volatility rising, the change in these derivatives indicators suggests that traders have become increasingly cautious about the possibility of a meaningful recovery before expiry.

However, both PCR and Max Pain are dynamic indicators, particularly on expiry days when rapid changes in open interest can alter the positioning within a short period.

71,800–72,000 Emerges as a Tough Resistance Zone

A closer examination of the Call options data shows substantial additions in open interest across strike prices starting from 71,500.

Among these, the 72,000 Call strike recorded the highest fresh addition in open interest, followed by the 71,800 strike. Interestingly, these two levels also accounted for the largest outstanding Call positions.

This positioning makes the 71,800–72,000 zone particularly important for traders monitoring a potential intraday recovery.
The 71,800 strike is likely to act as the first significant resistance, while the concentration of positions at 72,000 suggests a stronger barrier at the higher level.

With Sensex already trading considerably below 72,000, Call writers appear to be holding an advantage. A recovery towards these strikes may encounter renewed pressure unless there is meaningful unwinding of outstanding Call positions.

A sustained move above 71,800, along with a reduction in Call open interest, would provide an early indication that bearish positioning is beginning to ease.

Put Writers Defend 71,500 as the Index Approaches Support

While Call positions remain concentrated at higher strikes, activity on the Put side points to an attempt to establish support at lower levels.

The 71,500 Put strike attracted the largest addition in open interest, followed by 71,300. In terms of total outstanding Put open interest, 71,500 occupied the top position, with 71,000 holding the second-largest concentration.

The distribution suggests that 71,500 has become an important near-term support level, particularly as the index was trading close to this zone during the afternoon session.

The next level to monitor would be 71,300, where fresh Put additions were visible. Below that, the significant concentration of outstanding positions at 71,000 could make it another area of interest for traders.

Nevertheless, the presence of substantial Put open interest does not guarantee that these levels will hold. If the index continues to weaken, Put writers may start unwinding their positions, potentially adding to the pressure on the downside.

As a result, the market's ability to remain above 71,500 could play an important role in determining the direction of trade during the closing hours.

Nearly 3.92 Crore More Call Positions Than Puts

The difference between total Call and Put open interest provides another perspective on the prevailing market positioning.
According to the data recorded up to 1:54 PM, total Call open interest stood at 11.03 crore, substantially higher than the 7.11 crore recorded on the Put side.

This translates into a difference of 3.92 crore in outstanding open interest, highlighting the dominance of Call positions during the session.

The figures show that outstanding Call positions significantly exceed Put positions, consistent with the resistance structure developing above the prevailing market price.

However, total open interest represents existing positions and does not independently distinguish between fresh writing and buying. The bearish assessment is therefore better understood in conjunction with the reported increase in Call open interest, weakness in Sensex and the decline in PCR.

What Traders Should Watch During the Final Expiry Hours

With Sensex down more than 1,050 points and India VIX trading above 15, volatility could remain elevated as traders adjust or close their positions ahead of the weekly expiry.

From a derivatives perspective, 71,500 and 71,800 are the immediate levels worth tracking, while Max Pain at 71,700 provides an additional reference for the current options positioning.

If Sensex manages to hold above 71,500, some stability could emerge, although any meaningful recovery would need to overcome resistance at 71,800. Beyond this, 72,000 remains a major obstacle because of the heavy concentration of Call open interest.

On the other hand, a decisive break below 71,500 could bring 71,300 into focus. Should selling pressure persist, the next notable Put open interest concentration lies at 71,000.

The broader derivatives picture continues to lean towards the bearish side. A lower PCR, the 600-point downward movement in Max Pain and the large accumulation of Call positions at higher strikes collectively suggest that sellers retain an advantage.
