Bank Of India Sees Sharp Open Interest Surge Amid Strong Price Momentum

Open Interest and Volume Dynamics

On 19 Jan 2026, Bank Of India’s open interest (OI) in futures and options contracts rose sharply by 3,197 contracts, a 15.0% increase from the previous tally of 21,319 to 24,516. This notable expansion in OI was accompanied by a substantial volume of 43,431 contracts traded, reflecting active participation in the derivatives market. The combined futures and options value stood at approximately ₹63,615 lakhs, with futures contributing ₹57,393 lakhs and options ₹31,556 crores, indicating a sizeable notional exposure.

The rise in OI alongside elevated volume typically suggests fresh positions are being established rather than existing ones being squared off. This pattern often points to a directional conviction among market participants, with the current data implying a tilt towards bullish bets on Bank Of India’s stock.

Price Performance and Technical Strength

Bank Of India’s underlying equity price has mirrored the positive derivatives activity, hitting a new 52-week high of ₹164.34 during intraday trading, marking a 4.45% gain on the day. The stock has outperformed its sector by 4.22% and the broader Sensex by over 4.4%, with a one-day return of 3.94% compared to the sector’s -0.77% and Sensex’s -0.54% declines.

Notably, the stock has recorded four consecutive days of gains, delivering an impressive 11.93% return over this period. It is trading above all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling sustained upward momentum and technical strength. Such a confluence of positive price action and moving average support often attracts further buying interest from both retail and institutional investors.

Investor Participation and Liquidity

Investor engagement has surged, as evidenced by the delivery volume of 66.76 lakh shares on 16 Jan 2026, which represents an 82.49% increase over the five-day average delivery volume. This heightened delivery volume indicates genuine accumulation rather than speculative trading, reinforcing the bullish narrative.

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 ensures that large trades can be executed without significant price impact, an important factor for institutional investors and large traders.

Market Positioning and Directional Bets

The surge in open interest, combined with rising prices and volumes, suggests that market participants are increasingly positioning for an upward move in Bank Of India’s shares. The 15.0% increase in OI is significant in the context of the stock’s recent price rally, indicating that fresh long positions are being initiated rather than profit-taking or short covering.

Options market data, with an options value exceeding ₹31,556 crores, points to active hedging and speculative activity. The elevated options premium and open interest hint at a growing interest in call options, which are typically used to express bullish views or hedge existing long positions. This aligns with the stock’s strong technical setup and positive momentum.

Fundamental and Market Context

Bank Of India, a mid-cap public sector bank with a market capitalisation of approximately ₹72,865 crore, has been steadily improving its fundamentals and market perception. The stock’s Mojo Score stands at 78.0, with a current Mojo Grade of Buy, following a recent downgrade from Strong Buy on 23 Oct 2025. This adjustment reflects a more measured optimism, balancing the stock’s strong technicals with valuation and sectoral considerations.

The bank’s sector, Public Sector Banks, has faced headwinds in recent years but is now showing signs of recovery, supported by improving asset quality and credit growth. Bank Of India’s outperformance relative to its sector peers and the broader market underscores its potential as a key beneficiary of this turnaround.

Risks and Considerations

Despite the positive momentum, investors should remain cautious of potential volatility arising from macroeconomic factors, regulatory changes, and sector-specific risks. The derivatives market’s increased activity can sometimes precede sharp price corrections if market sentiment shifts abruptly. Additionally, the downgrade from Strong Buy to Buy signals that while the stock remains attractive, investors should monitor valuation levels and broader market conditions closely.

Outlook and Investor Takeaway

Bank Of India’s recent surge in open interest and volume, coupled with strong price performance and rising investor participation, paints a bullish picture for the near term. The stock’s ability to sustain gains above key moving averages and its outperformance relative to sector and benchmark indices suggest that it remains a compelling opportunity within the public sector banking space.

Investors should consider the stock’s current Buy rating and Mojo Score of 78.0 as indicators of favourable risk-reward dynamics, while remaining vigilant to market developments and valuation metrics. The derivatives market activity provides valuable insight into institutional and retail sentiment, signalling confidence in the stock’s upward trajectory.

Overall, Bank Of India appears well-positioned to capitalise on sectoral recovery and broader economic growth, making it a stock to watch closely in the coming weeks.
