Open Interest and Volume Dynamics
On 19 Jan 2026, Bank Of India’s open interest (OI) in derivatives rose sharply by 2,144 contracts, a 10.06% increase from the previous tally of 21,319 to 23,463. This notable expansion in OI was accompanied by a volume of 26,440 contracts, underscoring active trading and fresh positioning by market participants. The futures value stood at ₹36,939.06 lakhs, while the options segment exhibited a substantial notional value of approximately ₹18,652.07 crores, culminating in a total derivatives value of ₹40,533.39 lakhs.
The underlying stock price closed at ₹160, having touched an intraday high of ₹163.2, marking a 3.72% gain on the day. This price action coincided with the stock outperforming its sector by 2.66%, while the broader Sensex and banking sector indices declined by 0.68% and 0.23% respectively. Such divergence highlights Bank Of India’s relative strength amid a cautious market environment.
Technical and Trend Analysis
Bank Of India has been on a consistent upward trajectory, recording gains for four consecutive sessions and delivering a cumulative return of 10.34% over this period. The stock is trading above all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a strong bullish trend and positive investor sentiment. The recent surge to a new 52-week high at ₹163.2 further reinforces the momentum underpinning the stock.
Investor participation has also intensified, 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 volume suggests genuine accumulation rather than speculative trading, which bodes well for sustained price appreciation.
Market Positioning and Directional Bets
The sharp increase in open interest alongside rising volumes typically indicates fresh long positions being established or short positions being covered. Given the concurrent price appreciation and positive technical signals, it is reasonable to infer that market participants are positioning for further upside in Bank Of India’s shares. The derivatives market data suggests a bullish bias, with traders likely anticipating continued strength driven by improving fundamentals or sectoral tailwinds.
Bank Of India’s market capitalisation stands at ₹72,865 crores, categorising it as a mid-cap stock within the public sector banking industry. Its Mojo Score of 78.0 and a current Mojo Grade of Buy (downgraded from Strong Buy on 23 Oct 2025) reflect a solid investment case supported by favourable financial metrics and market positioning. The market cap grade of 2 indicates moderate liquidity and institutional interest, which is consistent with the observed trading activity.

Comparative Sector and Market Context
While the broader banking sector and Sensex indices have shown muted or negative returns recently, Bank Of India’s outperformance is noteworthy. The stock’s 1-day return of 2.59% contrasts sharply with the sector’s decline of 0.23% and the Sensex’s fall of 0.68%. This relative strength may be attributed to improving asset quality, better-than-expected earnings outlook, or strategic initiatives undertaken by the bank to enhance operational efficiency.
Liquidity metrics also support active trading in Bank Of India shares. The stock’s liquidity, based on 2% of the five-day average traded value, comfortably accommodates trade sizes up to ₹3.46 crores, making it accessible for institutional investors and large traders without significant market impact.
Implications for Investors and Traders
The surge in open interest combined with rising prices and volumes suggests that market participants are increasingly confident in Bank Of India’s near-term prospects. Traders may view this as an opportunity to establish or add to long positions, anticipating further gains. However, investors should remain mindful of broader macroeconomic factors and sector-specific risks that could influence the stock’s trajectory.
Given the stock’s recent upgrade to a Buy rating from a Strong Buy, the current valuation and momentum appear attractive but warrant close monitoring for any signs of profit booking or volatility. The sustained rise in delivery volumes indicates genuine investor interest, which could provide a stable base for future appreciation.

Outlook and Conclusion
Bank Of India’s recent derivatives activity and price performance signal a positive market outlook. The 10.06% increase in open interest, coupled with rising volumes and a new 52-week high, reflects strong bullish sentiment and fresh capital inflows. The stock’s ability to outperform its sector and the broader market during a period of general weakness further underscores its resilience and potential for continued gains.
Investors should consider the stock’s fundamentals, technical strength, and market positioning when making decisions. While the downgrade from Strong Buy to Buy suggests a slight moderation in enthusiasm, the overall Mojo Score of 78.0 and robust trading metrics support a constructive stance. Monitoring open interest trends and volume patterns will remain crucial to gauge evolving market sentiment and directional bets.
In summary, Bank Of India stands out as a mid-cap public sector bank exhibiting strong momentum and increasing investor interest, making it a compelling candidate for those seeking exposure to the banking sector’s growth story.
