Open Interest and Volume Dynamics
The latest data reveals that AU Small Finance Bank’s open interest increased by 5,922 contracts from the previous 33,697, marking a substantial 17.57% rise. This surge in OI is complemented by a daily volume of 33,496 contracts, indicating heightened trading activity and investor engagement in the derivatives market. The futures segment alone accounted for a value of approximately ₹1,44,799 lakhs, while options contributed a staggering ₹20,129.7 crores, culminating in a total derivatives value of ₹1,46,712.5 lakhs.
This spike in open interest, coupled with strong volume, often suggests that fresh positions are being established rather than existing ones being squared off. Such a pattern typically points to increased conviction among traders regarding the stock’s near-term price direction.
Price Performance and Technical Indicators
AU Small Finance Bank’s underlying price closed at ₹1,030, just 0.97% shy of its 52-week high of ₹1,039.2. The stock outperformed its sector by 0.73% on the day, delivering a 1.12% return compared to the sector’s 0.47% and the Sensex’s 0.62%. Notably, the share price is trading above all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a strong bullish trend and sustained investor confidence.
However, despite the positive price momentum, delivery volumes have declined sharply. On 19 Feb 2026, delivery volume stood at 9.52 lakh shares, down 30.68% against the 5-day average delivery volume. This suggests that while speculative activity in derivatives is rising, actual investor participation in the cash segment is moderating, possibly indicating a preference for leveraged exposure over outright stock ownership.

Market Positioning and Directional Bets
The pronounced increase in open interest alongside rising futures and options values indicates that market participants are positioning for a potential upward move in AU Small Finance Bank’s stock price. The futures value of ₹1,44,799 lakhs and options value exceeding ₹20,129 crores reflect significant capital allocation towards this stock’s derivatives, underscoring strong speculative interest.
Given the stock’s proximity to its 52-week high and its outperformance relative to the sector and benchmark indices, traders appear confident in the bank’s growth prospects. The MarketsMOJO Mojo Score of 72.0 and an upgraded Mojo Grade from Hold to Buy as of 09 Feb 2026 further reinforce this positive outlook. The mid-cap bank’s market capitalisation stands at ₹76,910.91 crores, placing it in a competitive position within the Other Bank sector.
Such positioning often reflects expectations of favourable quarterly results, robust loan growth, or improved asset quality, which could drive the stock higher. However, the decline in delivery volumes suggests that investors may be favouring short-term leveraged plays over long-term accumulation, a factor that warrants cautious monitoring.
Liquidity and Trading Viability
Liquidity remains adequate for sizeable trades, with the stock’s traded value supporting a trade size of approximately ₹4.76 crores based on 2% of the 5-day average traded value. This level of liquidity ensures that institutional and retail traders can enter and exit positions without significant price impact, facilitating active derivatives trading.
Moreover, the stock’s consistent trading above all major moving averages indicates strong technical support, which may attract momentum traders and algorithmic strategies, further amplifying volume and open interest.

Implications for Investors and Traders
The surge in open interest and volume in AU Small Finance Bank’s derivatives signals a growing consensus among traders that the stock is poised for further gains. The upgrade in Mojo Grade to Buy and a strong Mojo Score of 72.0 corroborate this positive sentiment, suggesting that the bank’s fundamentals and technicals are aligned for an upward move.
Investors should, however, remain vigilant about the divergence between derivatives activity and cash market delivery volumes. While derivatives indicate bullish bets, the falling delivery volumes may imply that long-term investor conviction is not yet fully established. This dynamic could lead to increased volatility, especially around key corporate announcements or macroeconomic developments.
Given the stock’s mid-cap status and sector positioning, it remains sensitive to broader banking sector trends and regulatory changes. Traders might consider monitoring open interest changes alongside price action and volume to gauge the strength of the ongoing trend and adjust their strategies accordingly.
Conclusion
AU Small Finance Bank Ltd’s recent open interest surge in derivatives, combined with strong volume and price momentum, highlights a bullish market stance among traders. The stock’s technical strength, supported by an upgraded Mojo Grade and solid fundamentals, positions it favourably within the Other Bank sector. However, the contrasting decline in delivery volumes suggests a nuanced market environment where speculative interest is high but long-term investor participation is subdued.
For investors and traders alike, this scenario underscores the importance of a balanced approach—leveraging derivatives insights while keeping an eye on cash market trends and broader sector developments to make well-informed decisions.
