Open Interest and Volume Dynamics
The latest data reveals that AU Small Finance Bank’s open interest in futures and options contracts rose sharply to 37,489 from the previous 31,660, marking an 18.41% increase. This 5,829-contract jump in OI is accompanied by a substantial volume of 52,181 contracts traded, underscoring active participation from derivatives traders. The combined futures and options value stands at approximately ₹98,758 lakhs, with futures alone accounting for ₹94,373 lakhs, indicating a sizeable notional exposure in the market.
Such a pronounced increase in open interest alongside elevated volumes typically signals fresh positions being established rather than existing ones being squared off. This suggests that market participants are positioning themselves for a directional move, with the underlying stock price currently at ₹1,023.
Price and Technical Context
AU Small Finance Bank’s price action supports the bullish narrative. The stock outperformed its sector by 0.86% on the day of analysis, while the broader Sensex and the Other Bank sector declined by 0.85% and 0.88% respectively. This relative strength is further reinforced by the stock trading above all key moving averages – 5-day, 20-day, 50-day, 100-day, and 200-day – indicating a sustained uptrend across multiple timeframes.
Investor participation has also surged, with delivery volumes reaching 20.18 lakh shares on 18 Feb 2026, a 73.2% increase compared to the five-day average. This rise in delivery volume points to genuine accumulation rather than speculative intraday trading, adding weight to the bullish outlook.

Market Positioning and Sentiment Analysis
The surge in open interest, coupled with rising volumes and price strength, indicates that traders are increasingly bullish on AU Small Finance Bank. The stock’s Mojo Score of 72.0 and an upgraded Mojo Grade from Hold to Buy as of 9 Feb 2026 further validate this positive sentiment. This upgrade reflects improved fundamentals, technicals, and market positioning, signalling confidence among analysts and investors alike.
Despite a marginal day change of -0.16%, the stock’s outperformance relative to its sector and benchmark indices suggests that the derivatives market is anticipating further upside. The market cap of ₹76,428.56 crore places AU Small Finance Bank firmly in the mid-cap category, offering a blend of growth potential and liquidity.
Liquidity and Tradeability
Liquidity remains robust, with the stock’s traded value supporting a trade size of approximately ₹4.74 crore based on 2% of the five-day average traded value. This ensures that institutional and retail investors can execute sizeable trades without significant market impact, an important consideration for derivatives traders establishing or unwinding positions.
The combination of high liquidity, rising open interest, and strong delivery volumes creates a conducive environment for sustained price discovery and trend continuation.
Potential Directional Bets and Strategy Implications
The open interest increase of 18.41% suggests fresh long positions are being built, likely reflecting expectations of continued price appreciation. Traders may be employing futures contracts to leverage their bullish views, while options activity could be skewed towards call buying or put selling strategies to capitalise on anticipated upward momentum.
Given the stock’s recent new 52-week high and technical strength, momentum traders may view this as a confirmation to add exposure. Meanwhile, value-oriented investors might interpret the delivery volume spike as institutional accumulation, signalling confidence in the bank’s medium-term prospects.
However, investors should remain mindful of broader market conditions and sectoral trends, as banking stocks can be sensitive to macroeconomic factors such as interest rate changes and regulatory developments.
