Aditya Birla Capital’s Mixed Week: -0.32% Price, 12.9% Open Interest Surge Tell the Story

Feb 23: Open Interest Surges Amid Mixed Signals

On 23 February 2026, Aditya Birla Capital saw a 17.67% surge in open interest in its derivatives segment, rising from 34,976 to 41,158 contracts. Despite this heightened activity, the stock price showed muted gains, closing at Rs.346.30, up 0.35%, slightly underperforming the Sensex’s 0.39% rise. The futures volume was robust at 24,021 contracts, with a combined derivatives turnover of ₹1,52,881 lakhs, reflecting strong liquidity.

Technically, the stock traded above its 100-day and 200-day moving averages but remained below short-term averages, indicating consolidation. Delivery volumes increased by 7.29% to 26.71 lakh shares, signalling genuine investor interest. The mixed price action alongside rising open interest suggested cautious positioning, with some investors possibly hedging via protective puts amid a challenging NBFC sector environment.

Feb 25: Bullish Momentum Accompanies Open Interest Rise

By 25 February, the stock gained momentum, closing at Rs.353.25, a 1.13% increase, outperforming the Sensex’s 0.41% gain. Open interest rose 11.54% to 28,675 contracts, supported by a strong volume of 22,412 contracts. The stock traded near its 52-week high of Rs.369.3, buoyed by a bullish technical setup with prices above all key moving averages.

Delivery volumes surged to 72.21 lakh shares, a 126.44% increase over the five-day average, indicating strong accumulation. The derivatives market activity suggested fresh long positions, reflecting growing investor confidence amid sectoral tailwinds. The stock outperformed its NBFC peers, which declined marginally, underscoring its relative strength.

Feb 26: Upgrade to Buy and Technical Momentum Shift

On 26 February, MarketsMOJO upgraded Aditya Birla Capital from 'Hold' to 'Buy', reflecting strong fundamentals and bullish technical indicators. The stock closed at Rs.355.90, up 0.75%, trading within a range of Rs.350.20 to Rs.359.90, approaching its 52-week high. The upgrade was supported by robust quarterly results, including a 40.5% rise in PAT to Rs.994.41 crores and a 27.40% increase in net sales.

Technical indicators shifted from mildly bullish to bullish, with daily moving averages aligned positively and Bollinger Bands signalling strength. The MACD showed a bullish monthly trend despite a mildly bearish weekly reading, while RSI remained neutral, suggesting room for further gains. On-balance volume confirmed strong buying interest, reinforcing the positive outlook.

Despite a premium valuation with a price-to-book ratio of 2.9 and moderate ROE of 10.1%, the stock’s market-beating returns over one, three, and five years justified the upgrade. Institutional holdings increased to 20.5%, signalling confidence in the company’s governance and growth trajectory.

Feb 27: Sharp Open Interest Surge Amid Price Reversal

The week ended with a notable 12.9% rise in open interest to 29,059 contracts on 27 February, despite the stock’s sharp 3.34% decline to Rs.344.00. The stock underperformed both its NBFC peers and the Sensex, which fell 1.16%. Delivery volumes dropped by 49.63% to 29.67 lakh shares, indicating reduced conviction among long-term holders.

Price action showed a reversal after five consecutive days of gains, with the stock trading below its 5-day and 50-day moving averages but remaining above longer-term averages. The mixed technical signals and rising open interest amid falling prices suggest fresh short positions or hedging activity. The substantial derivatives notional value of ₹68,472 lakhs highlights active market participation despite the cautious stance.

Weekly Price Performance: Aditya Birla Capital vs Sensex

Key Takeaways

Positive Signals: The stock demonstrated resilience by outperforming the Sensex’s weekly decline, supported by strong derivatives market activity and a significant upgrade to a Buy rating. Robust quarterly financials with a 40.5% PAT increase and sustained long-term growth underpin the fundamental strength. Technical momentum shifted bullish, with key indicators such as Bollinger Bands and moving averages signalling potential for further gains.

Cautionary Signals: Despite the upgrade, the stock’s premium valuation with a P/B ratio of 2.9 and moderate ROE of 10.1% warrant careful monitoring. The sharp price reversal on the final trading day, accompanied by a 12.9% surge in open interest and declining delivery volumes, suggests increased short-term uncertainty and potential volatility. Mixed technical signals, including mildly bearish weekly MACD and Dow Theory readings, advise prudence.

Conclusion

Aditya Birla Capital Ltd’s week was characterised by a complex interplay of bullish fundamentals and cautious near-term technical signals. The upgrade to a Buy rating and strong quarterly results provide a solid foundation for medium-term growth, while the derivatives market activity reflects active repositioning by investors amid evolving sector dynamics. The stock’s relative outperformance against the Sensex highlights its resilience within the NBFC space.

However, the late-week price correction and rising open interest amid falling prices indicate that investors are balancing optimism with risk management. Market participants should closely monitor technical momentum and derivatives trends to gauge the sustainability of the current rally. Overall, the stock remains a key focus for institutional and retail investors navigating a volatile market environment.
