Vodafone Idea Ltd Sees Sharp Open Interest Surge Amidst Weak Price Performance

Open Interest and Volume Dynamics

On 23 Feb 2026, Vodafone Idea’s open interest (OI) in derivatives rose sharply to 1,54,328 contracts from 1,39,474 contracts previously, marking an increase of 14,854 contracts or 10.65%. This expansion in OI indicates that new positions are being established rather than closed, reflecting growing interest in the stock’s future price movement. The volume for the day stood at 51,386 contracts, supporting the notion of active trading and fresh commitments by market participants.

In terms of value, the futures segment accounted for approximately ₹2,89,886 lakhs, while the options segment was significantly larger at ₹12,222,196,410 lakhs, culminating in a total derivatives value of ₹2,93,360 lakhs. The underlying stock price was ₹11, underscoring the relatively low price level at which these derivative contracts are being traded.

Price Performance and Moving Averages

Despite the surge in derivatives activity, Vodafone Idea’s stock price has been under pressure. The stock has declined by 1.43% on the day, underperforming its sector by 1.95% and the Sensex by 1.10%. Over the past three consecutive trading sessions, the stock has lost 4.93% in value, reflecting sustained selling pressure. Notably, the stock price remains above its 100-day and 200-day moving averages but is trading below the 5-day, 20-day, and 50-day moving averages, indicating short-term weakness amid longer-term support levels.

Investor participation has also waned, with delivery volume on 20 Feb falling by 14.78% to 7.72 crore shares compared to the five-day average. This decline in delivery volume suggests reduced conviction among long-term holders, potentially increasing volatility in the near term.

Market Positioning and Directional Bets

The increase in open interest alongside falling prices often signals that traders are building short positions or hedging existing long exposures. Given Vodafone Idea’s current Mojo Score of 33.0 and a Mojo Grade of Sell—upgraded from Strong Sell on 17 Oct 2025—the market sentiment remains cautious. The company’s mid-cap status with a market capitalisation of ₹1,19,611 crore places it in a segment where volatility can be pronounced, especially amid sectoral headwinds in Telecom - Services.

Traders may be positioning for further downside or volatility, as reflected by the sizeable options value, which dwarfs futures value. This disparity suggests that option strategies such as protective puts or speculative calls could be in play, indicating uncertainty about the stock’s near-term direction.

Sectoral Context and Comparative Performance

The Telecom - Services sector has been grappling with competitive pressures, regulatory challenges, and capital expenditure demands. Vodafone Idea’s underperformance relative to its sector peers, which gained 0.46% on the day, highlights company-specific concerns. The stock’s liquidity remains adequate for sizeable trades, with a 2% threshold of the five-day average traded value allowing for Rs 7.77 crore trade sizes, ensuring that institutional investors can execute positions without significant market impact.

Despite the recent upgrade from Strong Sell to Sell, the company’s Mojo Grade remains low, reflecting ongoing fundamental and technical challenges. The market appears to be pricing in continued uncertainty, with the derivatives market activity underscoring a cautious stance among traders.

Implications for Investors and Traders

The surge in open interest combined with falling prices and declining delivery volumes suggests that market participants are either increasing bearish bets or hedging against further downside. Investors should be wary of potential volatility spikes and monitor key technical levels, especially the 100-day and 200-day moving averages, which currently provide some support.

Given Vodafone Idea’s current valuation and market positioning, traders might consider strategies that benefit from volatility or downside risk, such as buying puts or employing spread strategies in options. Long-term investors should weigh the company’s fundamental outlook and sector dynamics before increasing exposure.

Outlook and Conclusion

Vodafone Idea Ltd.’s recent surge in derivatives open interest amid a weakening price trend highlights a complex market environment. While the increase in OI signals active positioning, the directional bias appears cautious to bearish given the stock’s underperformance and declining investor participation. The company’s Mojo Grade of Sell reflects ongoing challenges, despite a slight improvement from Strong Sell.

Investors and traders should closely monitor the evolving derivatives activity and price action for clues on future direction. The sizeable options market activity suggests that volatility could remain elevated, offering both risks and opportunities depending on one’s market view and risk appetite.

In summary, Vodafone Idea Ltd. remains a stock under scrutiny, with derivatives market data providing valuable insights into market sentiment and positioning. Careful analysis and risk management will be essential for those considering exposure in this telecom mid-cap.
