Bandhan Bank Sees Sharp Open Interest Surge Amid Mixed Market Signals

Open Interest and Volume Dynamics

On 27 Jan 2026, Bandhan Bank's open interest (OI) in derivatives rose sharply to 51,774 contracts from 46,050 the previous session, marking an increase of 5,724 contracts or 12.43%. This uptick in OI was accompanied by a futures volume of 38,936 contracts, indicating robust trading activity. The futures value stood at approximately ₹1,33,286.68 lakhs, while the options segment exhibited an enormous notional value of ₹7,856.26 crores, culminating in a total derivatives value exceeding ₹1,35,323 lakhs.

The underlying stock price was ₹148, reflecting a slight decline of 0.54% on the day, underperforming the private sector banking sector by 0.63% and lagging behind the Sensex's modest 0.23% gain. This divergence between derivatives activity and spot price movement suggests that market participants may be positioning for potential volatility or directional shifts in the near term.

Market Positioning and Investor Sentiment

The surge in open interest alongside elevated volumes often indicates fresh capital entering the market or existing participants increasing their exposure. In Bandhan Bank's case, the rising OI coupled with a slight price dip points to a complex scenario where both bullish and bearish bets coexist. Traders might be employing derivatives to hedge existing positions or speculate on anticipated price movements amid uncertain macroeconomic conditions.

Notably, the stock has recently reversed its short-term uptrend, falling after two consecutive days of gains. While Bandhan Bank's price remains above its 5-day, 20-day, and 50-day moving averages, it continues to trade below its 100-day and 200-day averages, indicating a mixed technical outlook. This pattern often attracts derivative traders seeking to capitalise on potential trend reversals or volatility spikes.

Rising Investor Participation and Liquidity

Investor participation has surged significantly, with delivery volumes on 23 Jan reaching 2.67 crore shares, a remarkable 479.1% increase compared to the five-day average delivery volume. This heightened engagement underscores growing interest in the stock from long-term investors, even as short-term traders adjust their positions in the derivatives market.

Liquidity remains adequate for sizeable trades, with the stock supporting a trade size of approximately ₹6.52 crore based on 2% of the five-day average traded value. Such liquidity levels are conducive to active derivatives trading and facilitate efficient price discovery.

Mojo Score and Analyst Ratings

Bandhan Bank currently holds a Mojo Score of 38.0, categorised as a 'Sell' rating, a downgrade from its previous 'Hold' status as of 31 Oct 2025. This shift reflects a deterioration in the stock’s fundamental and technical outlook, as assessed by MarketsMOJO’s proprietary scoring system. The market capitalisation grade stands at 3, indicating a small-cap status with moderate liquidity and market presence.

Such a rating downgrade often influences derivatives traders, who may increase put option buying or short futures positions to hedge against further downside risks. Conversely, some speculative participants might view the elevated open interest as an opportunity to capitalise on potential rebounds or volatility-driven price swings.

Sector and Market Context

Within the private sector banking industry, Bandhan Bank's recent underperformance contrasts with the sector’s modest gains, highlighting stock-specific challenges. The bank’s price movement and derivatives activity must be analysed in the context of broader economic indicators, regulatory developments, and sectoral trends impacting credit growth and asset quality.

Given the mixed technical signals and increased derivatives positioning, investors should closely monitor upcoming quarterly results, policy announcements, and macroeconomic data releases that could influence Bandhan Bank’s trajectory.

Implications for Investors and Traders

The pronounced increase in open interest and volume in Bandhan Bank’s derivatives signals a market bracing for potential price volatility. Traders should consider the implications of the stock’s technical positioning — trading above short-term moving averages but below longer-term ones — which often precedes significant directional moves.

For long-term investors, the recent surge in delivery volumes suggests renewed confidence in the stock’s fundamentals despite short-term price fluctuations. However, the downgrade to a 'Sell' Mojo Grade advises caution and thorough due diligence before increasing exposure.

Derivatives traders might find opportunities in both directions: bullish strategies could be employed if the stock breaks above its 100-day moving average, while protective puts or short futures could hedge against further declines. Monitoring open interest changes in call and put options separately would provide deeper insight into market sentiment and directional bias.

Conclusion

Bandhan Bank Ltd.’s recent surge in open interest and trading volumes in the derivatives market reflects a complex and evolving investor landscape. While the stock’s price has shown signs of weakness relative to its sector and broader indices, increased investor participation and liquidity underpin active market interest. The downgrade in Mojo Grade to 'Sell' adds a note of caution, suggesting that investors and traders should carefully weigh risks and opportunities amid mixed technical and fundamental signals.

As the market digests upcoming financial results and macroeconomic developments, Bandhan Bank’s derivatives activity will remain a key barometer of investor expectations and potential price direction.
