This represents a 22.28% change, signalling increased participation and potential accumulation of positions by market participants. Concurrently, the volume traded stood at 60,031 contracts, underscoring active trading interest in both futures and options segments.
In terms of value, futures contracts accounted for approximately ₹93,156.52 lakhs, while options contracts exhibited a substantially larger notional value of ₹51,430.34 crores. The combined derivatives value totals around ₹1,01,596.30 lakhs, indicating a robust derivatives market ecosystem supporting the stock’s price action.
Price Performance and Technical Context
AU Small Finance Bank touched a new 52-week high of ₹1,007.25 during intraday trading, reflecting a 3.62% rise on the day. The stock has recorded gains over the last two consecutive sessions, cumulatively delivering a 5.06% return in this period. This outperformance is notable against the sector’s 0.46% decline and the Sensex’s marginal 0.01% movement, highlighting relative strength.
Technically, the stock is trading above its key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — which often serves as a bullish indicator for momentum traders and institutional investors alike. However, delivery volumes have shown a slight contraction, with 8.41 lakh shares delivered on 9 December, down 8.17% compared to the five-day average. This suggests that while short-term trading activity is vigorous, longer-term investor participation may be moderating.
Market Capitalisation and Liquidity Considerations
AU Small Finance Bank is classified as a mid-cap entity with a market capitalisation of approximately ₹74,319 crore. The stock’s liquidity profile supports sizeable trade sizes, with a 2% threshold of the five-day average traded value allowing for transactions up to ₹2.93 crore without significant market impact. This liquidity is crucial for derivatives traders and institutional investors seeking to establish or unwind positions efficiently.

Interpreting the Open Interest Surge
The 22.28% rise in open interest for AU Small Finance Bank’s derivatives contracts suggests a growing conviction among traders and investors regarding the stock’s near-term trajectory. Open interest expansion typically indicates that new positions are being created rather than closed, which can be a precursor to sustained price trends.
Given the stock’s recent price appreciation and fresh highs, the increase in open interest may reflect directional bets favouring further upside. The substantial notional value in options contracts points to active hedging and speculative activity, with market participants possibly positioning for volatility or continuation of the bullish momentum.
Volume Patterns and Market Positioning
Volume data corroborates the open interest trend, with 60,031 contracts traded, signalling heightened market engagement. The balance between futures and options volumes and values indicates a diversified approach by traders, combining outright directional exposure with options strategies to manage risk or leverage potential moves.
While delivery volumes have shown a slight dip, this may reflect a shift towards more short-term trading and derivatives-based exposure rather than outright stock accumulation. Such a pattern is common in environments where traders seek to capitalise on momentum without committing to long-term holdings.
Sector and Benchmark Comparison
AU Small Finance Bank’s performance stands out within the Other Bank sector, which has experienced a modest decline of 0.46% on the day. The stock’s 2.82% gain contrasts with the near-flat movement of the Sensex, underscoring its relative strength and attractiveness to market participants.
This divergence may be driven by company-specific factors, including recent assessment changes and evolving market perceptions, which have encouraged increased derivatives activity and price appreciation.
