Open Interest and Volume Dynamics
On 19 February 2026, PNB's open interest in futures and options contracts rose sharply to 64,866 from the previous 57,531, marking an increase of 7,335 contracts or 12.75%. This surge in OI was accompanied by a volume of 77,987 contracts, indicating heightened trading activity and investor interest. The futures value stood at ₹2,31,125.6 lakhs, while the options segment contributed a substantial ₹58,196.11 crores, culminating in a total derivatives value of approximately ₹2,38,026.94 lakhs.
Such a pronounced increase in open interest, especially when paired with rising volumes, often reflects fresh capital entering the market rather than mere position squaring. This suggests that traders are establishing new positions, potentially anticipating further price movement in PNB's shares.
Price Performance and Technical Context
PNB's underlying stock price closed at ₹129, just 4.41% shy of its 52-week high of ₹135.15. The stock outperformed its sector by 1.49% on the day, registering a 2.79% gain compared to the Public Sector Bank sector's 1.19% and the Sensex's 0.62%. Intraday, the stock touched a high of ₹130.40, a 3.41% rise, reinforcing bullish sentiment.
Technically, PNB is trading above all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a sustained uptrend. This technical strength aligns with the surge in derivatives activity, as traders appear confident in the stock's near-term upside potential.
Market Positioning and Directional Bets
The increase in open interest alongside rising prices and volumes suggests that market participants are predominantly taking long positions, betting on further appreciation in PNB's share price. The futures and options data imply that institutional and retail traders alike are positioning for a bullish scenario, possibly anticipating positive developments in the public sector banking space or broader macroeconomic tailwinds.
However, it is noteworthy that delivery volumes have slightly declined by 0.79% against the 5-day average, with a delivery volume of 1.05 crore shares on 19 February. This could indicate that while speculative activity in derivatives is rising, actual investor participation in the cash segment is somewhat subdued, reflecting a preference for leveraged exposure over outright stock ownership.
Liquidity and Market Capitalisation Considerations
PNB remains a large-cap stock with a market capitalisation of ₹1,48,971.53 crores, ensuring ample liquidity for institutional trades. The stock's liquidity supports trade sizes up to ₹6.39 crores based on 2% of the 5-day average traded value, making it accessible for sizeable derivative positions without significant market impact.
Despite the recent downgrade in its Mojo Grade from Buy to Hold on 27 January 2026, with a current Mojo Score of 68.0, the stock's recent price action and derivatives activity suggest renewed investor interest. The downgrade reflects a more cautious stance, possibly due to valuation concerns or sectoral headwinds, but the market's positioning indicates optimism about near-term prospects.

Implications for Investors and Traders
The sharp rise in open interest and volume in PNB's derivatives contracts signals a growing conviction among traders about the stock's upside potential. Investors should note that such activity often precedes significant price moves, either confirming a trend or foreshadowing volatility.
Given the stock's proximity to its 52-week high and strong technical positioning, the current market sentiment appears bullish. However, the slight decline in delivery volumes suggests caution, as the underlying investor base may not be fully aligned with the speculative fervour in derivatives.
Traders looking to capitalise on this momentum should monitor open interest changes closely, alongside price and volume trends, to gauge the sustainability of the move. Additionally, keeping an eye on sectoral developments and macroeconomic indicators will be crucial, given PNB's sensitivity to broader banking sector dynamics.
Sector and Peer Context
Within the Public Sector Bank sector, PNB's outperformance relative to its peers and the broader Sensex highlights its relative strength. The sector has been under pressure due to concerns over asset quality and credit growth, but PNB's recent performance and derivatives activity suggest it may be emerging as a preferred play among investors.
Market participants should consider PNB's current Mojo Grade of Hold, reflecting a tempered outlook despite recent gains. This rating adjustment from Buy to Hold on 27 January 2026 indicates that while the stock remains attractive, investors should weigh valuation and risk factors carefully.

Conclusion
Punjab National Bank's recent surge in open interest and volume in the derivatives market underscores a renewed bullish sentiment among traders. The stock's strong technical positioning, coupled with its outperformance relative to sector and benchmark indices, supports the case for further upside potential.
Nevertheless, the downgrade in Mojo Grade to Hold and the slight dip in delivery volumes counsel prudence. Investors should balance the evident speculative enthusiasm with fundamental and sectoral considerations before making fresh commitments.
Overall, PNB remains a key stock to watch within the public sector banking space, with derivatives market activity providing valuable insights into evolving market expectations and positioning.
