Adani Power Sees Sharp Open Interest Surge Amid Mixed Market Signals

Open Interest and Volume Dynamics

On 24 Aug 2026, Adani Power Ltd (symbol: ADANIPOWER) recorded an open interest (OI) of 82,496 contracts, up from 73,876 the previous session, marking an increase of 8,620 contracts or 11.67%. This rise in OI was accompanied by a futures volume of 41,844 contracts, indicating robust trading activity in the derivatives market. The combined futures and options value stood at approximately ₹15,74,51.7 lakhs, with futures contributing ₹1,56,235.3 lakhs and options dominating at ₹15,35,76,685.3 lakhs, underscoring the significant interest in options strategies.

The underlying stock price hovered at ₹202, opening at ₹203.04 and trading flat at that level throughout the day. However, the stock's one-day return was negative at -1.23%, underperforming the Power sector's -0.30% and the Sensex's -0.37% declines. This divergence between derivatives activity and spot price performance suggests speculative positioning or hedging strategies at play.

Market Positioning and Moving Averages

Adani Power's price currently trades above its 200-day moving average, a long-term bullish indicator, but remains below its 5-day, 20-day, 50-day, and 100-day moving averages. This mixed technical picture points to short- and medium-term weakness despite a solid long-term base. The falling investor participation, evidenced by a 22.3% decline in delivery volume to 49.19 lakh shares on 21 Aug compared to the five-day average, further highlights cautious sentiment among long-term holders.

Liquidity remains adequate, with the stock supporting trade sizes up to ₹5.92 crore based on 2% of the five-day average traded value, ensuring that the recent surge in derivatives activity is supported by sufficient market depth.

Interpreting the Open Interest Surge

The 11.7% increase in open interest signals that new positions are being established rather than existing ones being closed. This often reflects growing conviction among traders about the stock’s future direction. However, the simultaneous decline in the stock price and underperformance relative to the sector suggests that the surge may be driven by bearish bets or hedging activity rather than outright bullish enthusiasm.

Options market data, with an overwhelming options value of over ₹15,35,76,685 lakhs, indicates that investors are actively using options strategies to manage risk or speculate. The large disparity between futures and options values suggests a preference for options, which can be used for both directional bets and volatility plays.

Given the stock’s current Mojo Score of 47.0 and a Mojo Grade downgraded from Hold to Sell on 14 Aug 2026, the market sentiment appears cautious. The downgrade reflects deteriorating fundamentals or technicals, which may be influencing the increased derivatives activity as traders position for potential downside or volatility.

Sector and Market Context

Adani Power operates within the Power industry, a sector that has shown modest declines recently. The stock’s market capitalisation of ₹3,91,440.73 crore classifies it as a large-cap, attracting institutional interest and making its derivatives activity particularly relevant for market participants seeking exposure to the sector.

While the stock’s delivery volumes have fallen, indicating reduced long-term investor participation, the derivatives market is seeing heightened activity, suggesting that short-term traders and speculators are increasingly active. This divergence often precedes significant price moves as market positioning adjusts to new information or technical triggers.

Potential Directional Bets and Investor Implications

The combination of rising open interest, heavy options activity, and a recent downgrade to a Sell rating suggests that market participants may be positioning for increased volatility or a downward correction in Adani Power’s share price. Traders could be employing protective puts or bearish spreads to hedge existing long exposure or speculate on declines.

Conversely, the stock’s position above the 200-day moving average provides a technical support level that could attract value buyers if the price dips further. The mixed moving average signals imply that short-term momentum is weak, but the long-term trend remains intact, creating a battleground for bulls and bears.

Investors should closely monitor changes in open interest alongside price action and volume to gauge the strength of these directional bets. A sustained increase in OI coupled with price declines would confirm bearish sentiment, while a reversal in price with rising OI might indicate accumulation and a potential rebound.

Conclusion

Adani Power Ltd’s recent surge in open interest and derivatives volume highlights a period of heightened market attention and repositioning. Despite the stock’s underperformance relative to its sector and the broader market, the active derivatives market suggests that traders are preparing for significant moves, likely influenced by the recent downgrade and mixed technical signals.

For investors, this environment calls for caution and close monitoring of both spot and derivatives markets. The stock’s large-cap status and liquidity make it a focal point for institutional strategies, while the divergence between delivery volumes and derivatives activity underscores the evolving market dynamics. Ultimately, understanding these shifts in open interest and positioning can provide valuable insights into Adani Power’s near-term trajectory and risk profile.
