Sensex Monthly Expiry: 77,500 Support, 77,800 Key Resistance


By Dalal Street Investment Journal (DSIJ)

Summary :

 

Sensex Monthly Expiry outlook remains positive as the index briefly crossed the 100-DMA near 77,691 before profit-booking emerged around 77,800. Compared to the morning setup, PE writers shifted support higher from 77,000 to 77,500, while CE writers moved resistance to 77,800–78,000. Sustaining above 77,691 is crucial for further upside, while 77,500 remains key support for the expiry trade today.

The BSE Sensex extended its gains and managed to move above the 100-DMA level of 77,691.55. The index went on to register an intraday high of 77,803.18, indicating that bulls made a serious attempt to push the index beyond the key resistance zone highlighted earlier. However, profit-booking emerged at higher levels, and around 12:55 PM, the Sensex was trading near 77,604, up nearly 600 points or 0.78%.

PCR Cools, But Bias Remains Positive

The Put-Call Ratio across all expiries has eased to 1.31 from the earlier level of 1.54.

The Max Pain level has shifted higher from 77,700 earlier to 77,800 now. This upward shift is important as it reflects a higher expiry expectation compared to the morning setup.

PE Writers Shift Base Higher

On the put side, the highest open interest addition continues to be seen at the 77,500 PE strike. More importantly, the maximum open interest concentration on the PE side has now shifted to 77,500 from the earlier 77,000 level. The 77,000 PE strike now holds the second-highest concentration.

This is a meaningful change from the morning data. Earlier, 77,000 was the main support base, while 77,500 emerged as fresh support. In the afternoon session, 77,500 has become the key support level, suggesting that PE writers have gained confidence and lifted their base higher as the index moved up.

CE Writers Move Resistance Higher, But 77,800 Remains Key Resistance

On the call side, the 77,800 CE strike has seen the highest open interest addition so far, followed by the 78,000 CE strike. In terms of overall open interest concentration, the highest OI remains at the 78,000 CE strike, followed by 77,800 CE.

Compared to the earlier setup, call writing has shifted higher. In the morning, aggressive call writing was visible around 77,600; now, the fresh addition has moved to 77,800. This indicates that CE writers were forced to adjust their positions after the Sensex crossed the 100-DMA zone. However, the heavy concentration at 78,000 still makes it the most important resistance for the day.

Sensex Expiry View on June 25

The overall setup remains positive, but the index needs to sustain above the 77,691–77,800 zone to strengthen the upside momentum. A move above 77,800 may lead to further call unwinding and open the path towards 78,000. On the downside, 77,500 has now become the key support level for the expiry session. As long as the Sensex holds above 77,500, the undertone may remain in favour of bulls. However, failure to sustain above the 100-DMA zone could keep the index in a narrow range with profit-booking at higher levels.

Updated as of 11:30AM IST

On Thursday, June 25, the day of Sensex monthly expiry, the BSE Sensex opened on a firm note and extended its gains as the session progressed. The index gained momentum in early trade and moved within striking distance of the May 8 swing high. Around 11:06 AM, the Sensex was trading near 77,500, up nearly 500 points or 0.67%.

Sensex Monthly Expiry Options Data Signals Positive Bias

The options data indicate a broadly positive undertone for the expiry session. The Put-Call Ratio (PCR) across all expiries stood at 1.54, suggesting stronger put writing compared to call writing. The Max Pain level was placed at 77,700.

On the put (PE) side, the 77,500 PE strike witnessed the highest open interest addition so far, followed by the 77,000 PE strike, which makes the 77,500–77,700 zone important for the remaining part of the session. The 77,400 and 77,300 PE strikes also saw notable additions, indicating that put writers are trying to build a support base below the current market price. In terms of overall open interest concentration, the highest OI remains at the 77,000 PE strike, followed by 77,500 PE.

Call Writers Active Near Immediate Resistance

On the call side, the 77,600 CE strike recorded the highest open interest addition on the monthly expiry day, followed by the 78,000 CE strike. The overall call open interest concentration is highest at the 78,000 CE strike, followed by 77,600 CE.

This clearly shows that while put writers are becoming active at lower levels, call writers are also defending the immediate resistance zone near 77,600–77,700. Hence, the next move will largely depend on whether the Sensex is able to sustain above this supply zone.

Key Resistance Zone for Sensex: 77,630–77,691

From a technical perspective, the Sensex faces strong resistance in the 77,630–77,691 range. This zone is important because the 100-DMA is placed around this area, along with the April 8 swing high. As long as the index remains below this band, call writers are likely to stay aggressive around the 77,600 and 77,700 CE strikes.

However, a sustained move above the 77,635-77,691 zone could trigger short-covering by call writers. In that case, the index may attempt to move towards the 78,000 mark, which is the next major resistance based on options data.

Sensex Monthly Expiry View

The setup remains positive as long as the Sensex holds above the 77,300–77,400 zone, where fresh put writing has been visible. However, the upside may remain capped unless the index decisively crosses and sustains above the 77,635–77,691 resistance band.

For the monthly expiry, the 77,500–77,700 zone is likely to remain the key battleground. A close above this zone would strengthen the bullish bias, while failure to cross it may keep the index range-bound with profit-booking at higher levels.
