Tata Power Sees Significant Open Interest Surge Amid Mixed Market Signals

Open Interest and Volume Dynamics

On 22 January 2026, Tata Power’s open interest (OI) in futures and options contracts rose sharply to 99,188 contracts from 89,836 the previous day, marking an increase of 9,352 contracts or 10.41%. This surge in OI was accompanied by a daily volume of 51,474 contracts, indicating robust trading activity. The futures value stood at ₹98,076.11 lakhs, while the options segment contributed a substantial ₹17,738.18 crores, culminating in a total derivatives value of approximately ₹1,02,230.30 lakhs.

The rising OI alongside strong volume typically reflects fresh positions being taken rather than existing ones being squared off, suggesting that traders are actively repositioning themselves in anticipation of future price movements. However, the stock’s underlying value at ₹352 remains below all key moving averages—5-day, 20-day, 50-day, 100-day, and 200-day—indicating a prevailing downtrend despite the recent price uptick.

Market Positioning and Directional Bets

The increase in open interest amid a slight price gain after six consecutive days of decline points to a potential battle between bulls and bears. The stock underperformed its sector by 0.4% on the day, with the power sector itself advancing 1.58%, while the broader Sensex rose 0.48%. This divergence suggests that while the sector enjoys positive momentum, Tata Power is facing headwinds possibly linked to company-specific factors or broader market sentiment.

Investor participation has notably risen, with delivery volumes reaching 18.71 lakh shares on 21 January, a 9.05% increase over the five-day average. This heightened delivery volume indicates stronger conviction among investors holding shares rather than merely trading derivatives, which could signal a foundational shift in sentiment.

Nevertheless, the company’s Mojo Score remains low at 26.0, with a Strong Sell grade assigned on 12 January 2026, an upgrade from a previous Sell rating. This downgrade in sentiment reflects concerns over Tata Power’s near-term fundamentals and technical outlook, despite the recent uptick in open interest and price.

Technical and Fundamental Context

Tata Power’s current trading below all major moving averages signals a bearish technical setup. The stock’s inability to break above these resistance levels despite increased open interest suggests that the recent surge in derivatives activity may be driven by speculative short-term bets rather than a sustained bullish reversal.

From a fundamental perspective, Tata Power’s market capitalisation stands at ₹1,12,923.30 crores, categorising it as a large-cap entity within the power sector. However, its Market Cap Grade is rated at 1, reflecting concerns about valuation or growth prospects relative to peers. The company’s recent Mojo Grade downgrade to Strong Sell further underscores the cautious stance adopted by analysts and investors alike.

Liquidity remains adequate, with the stock’s average traded value supporting trade sizes up to ₹2.67 crores, ensuring that institutional investors can enter or exit positions without significant price impact. This liquidity profile is crucial given the heightened derivatives activity and the potential for increased volatility.

Implications for Investors

The surge in open interest combined with rising delivery volumes and a modest price recovery after a prolonged decline presents a nuanced picture. While increased OI often signals fresh directional bets, the mixed technical signals and negative fundamental grades suggest caution. Investors should closely monitor whether the stock can sustain gains and break above key moving averages to confirm a trend reversal.

Conversely, failure to maintain the recent price levels could trigger further downside, especially given the strong sell rating and the stock’s underperformance relative to its sector. The derivatives market activity may also reflect hedging strategies or speculative positioning that could unwind quickly if market conditions shift.

Sector and Broader Market Comparison

Within the power sector, Tata Power’s recent performance contrasts with the sector’s 1.58% gain on the same day, highlighting company-specific challenges. The Sensex’s modest 0.48% rise further emphasises that Tata Power’s underperformance is not merely a reflection of broader market trends but likely linked to internal or sectoral factors.

Investors should weigh Tata Power’s derivatives market activity against these broader trends, recognising that while the sector remains buoyant, Tata Power’s outlook is clouded by technical weakness and a cautious fundamental assessment.

Outlook and Strategic Considerations

Given the current data, Tata Power appears to be at a critical juncture. The derivatives market’s increased open interest signals heightened interest and potential volatility ahead. However, the stock’s technical and fundamental indicators counsel prudence. Investors with a higher risk appetite may consider tactical positions aligned with short-term momentum, while those seeking stability might await clearer signs of trend confirmation or explore alternative power sector stocks with stronger ratings and momentum.

Monitoring upcoming quarterly results, sector developments, and macroeconomic factors impacting power demand and regulation will be essential to gauge Tata Power’s trajectory in the near term.

Summary

Tata Power Company Ltd’s recent 10.4% open interest increase in derivatives reflects active repositioning by market participants amid a fragile price recovery. Despite this, the stock remains technically weak and fundamentally challenged, with a Strong Sell Mojo Grade and underperformance relative to its sector. Investors should approach with caution, balancing the potential for short-term directional bets against the prevailing bearish signals.
