Punjab National Bank Sees Significant Open Interest Surge Amid Mixed Market Signals

Open Interest and Volume Dynamics

On 17 Feb 2026, PNB's open interest (OI) in futures and options contracts rose sharply to 64,750 contracts from 58,723 the previous day, marking an increase of 6,027 contracts or 10.26%. This expansion in OI is accompanied by a futures volume of 21,141 contracts, reflecting robust trading activity. The futures value stood at ₹1,11,216.3 lakhs, while the options segment exhibited an enormous notional value of approximately ₹9,499.08 crores, culminating in a total derivatives value exceeding ₹1,12,346.2 lakhs.

The underlying stock price closed at ₹121, outperforming its public sector banking peers by 0.7% and the sector by 0.22%, while the broader Sensex declined by 0.22%. PNB has recorded gains over the last two consecutive sessions, delivering a cumulative return of 2.27% during this period. Notably, the stock trades above its 100-day and 200-day moving averages, signalling medium- to long-term strength, although it remains below the shorter-term 5-day, 20-day, and 50-day averages, indicating some near-term consolidation.

Investor Participation and Liquidity Considerations

Despite the positive price momentum and rising open interest, investor participation appears to be waning. Delivery volume on 16 Feb 2026 was 51.52 lakh shares, down 18.46% compared to the five-day average delivery volume. This decline in delivery volume suggests that while speculative activity in derivatives is intensifying, actual shareholding by investors is moderating. The stock remains sufficiently liquid, with a trading capacity of approximately ₹3.47 crore based on 2% of the five-day average traded value, supporting sizeable trades without significant market impact.

Market Positioning and Directional Implications

The surge in open interest, coupled with rising volumes, typically indicates fresh positions being established rather than existing ones being squared off. In PNB's case, the 10.26% increase in OI alongside a modest price appreciation suggests that traders are building directional bets, possibly anticipating further upside in the near term. However, the stock's position below its short-term moving averages tempers this optimism, hinting at potential resistance levels that may cap gains.

Options market data, with an enormous notional value exceeding ₹9,499 crores, further underscores the intense speculative interest. The large options value relative to futures indicates that traders may be employing complex strategies such as spreads or hedges, reflecting a nuanced view of PNB's near-term prospects. This complexity is typical in large-cap public sector banks where regulatory developments, credit growth, and macroeconomic factors can rapidly influence sentiment.

Mojo Score and Analyst Ratings

MarketsMOJO assigns PNB a Mojo Score of 68.0, categorising it as a 'Hold' with a recent downgrade from a 'Buy' rating on 27 Jan 2026. The downgrade reflects a cautious stance amid mixed technical signals and evolving market dynamics. The bank's market capitalisation stands at a substantial ₹1,38,490 crore, placing it firmly in the large-cap segment, which typically attracts institutional interest and ensures adequate liquidity.

Sector and Broader Market Context

Within the public sector banking industry, PNB's recent outperformance relative to the sector and Sensex is noteworthy. The sector has been navigating challenges such as asset quality concerns and regulatory changes, which have led to divergent performances among peers. PNB's ability to sustain gains and attract derivative interest may indicate improving fundamentals or positive market sentiment towards its strategic initiatives.

However, the falling delivery volumes caution that retail and long-term investors may be less enthusiastic, possibly awaiting clearer signals before committing fresh capital. This divergence between derivatives activity and cash market participation is a critical factor for investors to monitor, as it may presage increased volatility or a shift in trend.

Investor Takeaways and Outlook

For investors, the recent spike in open interest and volume in PNB's derivatives market signals an active repositioning that could precede a significant price move. The current 'Hold' rating and Mojo Score of 68.0 suggest a balanced risk-reward profile, with neither strong bullish nor bearish conviction prevailing.

Given the stock's technical positioning—above long-term moving averages but below short-term ones—investors should watch for confirmation of trend direction through price action and volume in the coming sessions. The divergence between derivatives activity and declining delivery volumes also warrants caution, as it may indicate speculative positioning rather than broad-based investor confidence.

Market participants should also consider macroeconomic factors affecting the public sector banking space, including credit growth trends, asset quality developments, and regulatory announcements, which could materially impact PNB's trajectory.

Conclusion

Punjab National Bank's recent open interest surge in derivatives highlights a phase of heightened market interest and evolving positioning. While the stock has outperformed its sector peers modestly, mixed technical signals and falling investor participation in the cash market suggest a cautious approach. Investors are advised to monitor derivatives volumes, price trends, and broader sector developments closely to gauge the sustainability of current momentum and to identify potential entry or exit points.
