Open Interest and Volume Dynamics
On 19 Jan 2026, Bank Of India’s open interest in derivatives rose sharply by 3,445 contracts, a 16.16% increase from the previous OI of 21,319 to 24,764. This notable expansion in OI coincided with a robust volume of 38,582 contracts traded, underscoring active participation in the stock’s futures and options market. The futures segment alone accounted for a value of approximately ₹51,116.5 lakhs, while options contributed a staggering ₹27,636.02 crores, culminating in a total derivatives value of ₹56,667.7 lakhs.
This spike in open interest, coupled with elevated volumes, typically indicates fresh directional bets being placed by market participants. The increase suggests that traders are either initiating new positions or adding to existing ones, reflecting a consensus on the stock’s near-term trajectory.
Price Action and Technical Strength
Bank Of India’s underlying price has been on a strong upward trend, recently touching an intraday high of ₹164.34, marking a new 52-week peak. The stock outperformed its public sector banking peers by 4.47% on the day, while the broader sector and Sensex declined by 0.28% and 0.69% respectively. Over the past four consecutive trading sessions, the stock has delivered a cumulative return of 12.38%, signalling sustained buying interest.
Technically, the stock is trading above all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — indicating a strong bullish momentum. The weighted average price data reveals that a significant portion of volume was traded closer to the day’s low, suggesting accumulation by investors at relatively lower price points during the session.
Investor Participation and Liquidity
Investor participation has surged notably, with delivery volumes on 16 Jan reaching 66.76 lakh shares, an 82.49% increase compared to the five-day average delivery volume. This rise in delivery volumes indicates that investors are not merely trading intraday but are holding positions, reflecting confidence in the stock’s fundamentals and outlook.
Liquidity remains robust, with the stock’s average traded value supporting trade sizes up to ₹3.46 crore based on 2% of the five-day average traded value. This liquidity profile favours institutional and large traders looking to build or unwind sizeable positions without significant market impact.

Market Positioning and Directional Bets
The surge in open interest alongside rising prices and volumes suggests that market participants are increasingly bullish on Bank Of India. The stock’s mojo score currently stands at 78.0, with a mojo grade of Buy, reflecting a positive outlook despite a recent downgrade from Strong Buy on 23 Oct 2025. This adjustment indicates a more measured optimism, balancing strong fundamentals with valuation considerations.
Given the public sector banking sector’s mixed performance, Bank Of India’s outperformance is notable. The stock’s market capitalisation is ₹72,865 crore, placing it in the mid-cap category with a market cap grade of 2. The combination of rising open interest and sustained price gains points to fresh long positions being established, possibly in anticipation of favourable quarterly results or sectoral tailwinds such as improving asset quality and credit growth.
Options market data, with an exceptionally high notional value of ₹27,636 crores, indicates active hedging and speculative activity. The elevated option values suggest that traders are positioning for potential volatility, with directional bets likely skewed towards upside given the recent price momentum and technical strength.
Comparative Sector and Benchmark Analysis
While Bank Of India has gained 4.22% in a single day, the public sector banking sector declined by 0.28%, and the Sensex fell by 0.69%. This divergence highlights the stock’s relative strength and attractiveness amid broader market weakness. Investors seeking exposure to the banking sector may find Bank Of India’s current momentum and improving delivery volumes compelling compared to peers.
Moreover, the stock’s consistent gains over the past four sessions, coupled with rising open interest, suggest a sustained uptrend rather than a short-lived spike. This pattern is often indicative of institutional accumulation and positive sentiment among informed market participants.

Outlook and Investor Considerations
Bank Of India’s recent derivatives activity and price action suggest a constructive near-term outlook. The stock’s ability to sustain above key moving averages and maintain rising delivery volumes supports the thesis of institutional confidence. However, investors should remain mindful of sectoral risks such as asset quality pressures, regulatory changes, and macroeconomic factors impacting credit growth.
The downgrade from Strong Buy to Buy on 23 Oct 2025 reflects a cautious stance on valuation, but the mojo score of 78.0 still indicates a favourable risk-reward profile. Traders may consider monitoring open interest trends and volume patterns closely for signs of profit booking or further accumulation.
Given the stock’s liquidity and active derivatives market, Bank Of India remains a viable candidate for both medium-term investors and short-term traders seeking exposure to public sector banking with a positive momentum bias.
Summary
In summary, Bank Of India’s sharp increase in open interest and volume in the derivatives segment, combined with strong price performance and rising delivery volumes, signals robust market participation and bullish positioning. The stock’s outperformance relative to its sector and benchmark indices further underscores its appeal. While valuation concerns have moderated the rating slightly, the overall technical and fundamental backdrop remains supportive for continued gains.
Investors should continue to track derivatives activity and price momentum as key indicators of market sentiment and potential directional moves in Bank Of India.
