HDFC Asset Management Sees Sharp Open Interest Surge Amid Market Volatility

Open Interest and Volume Dynamics

On 19 Feb 2026, HDFCAMC's open interest rose sharply from 32,181 contracts to 35,550, an increase of 3,369 contracts or 10.47%. This rise in OI was accompanied by a volume of 25,574 contracts, indicating robust trading activity. The futures segment alone accounted for a value of approximately ₹79,024 lakhs, while options contributed a staggering ₹13,642.8 crores, culminating in a total derivatives value of ₹79,862 lakhs. Such figures underscore the growing interest in HDFCAMC's derivatives, reflecting active positioning by institutional and retail investors alike.

Interestingly, the underlying stock price has been under pressure, with a 2.75% decline on the day, underperforming the Capital Markets sector by 2.02% and the Sensex by 1.81%. The stock has also recorded a consecutive two-day fall, losing 4.37% cumulatively. Intraday lows touched ₹2,737.1, down 2.68%, despite the stock trading above its 20-day, 50-day, 100-day, and 200-day moving averages, though below its 5-day average. This divergence between price action and moving averages suggests short-term selling pressure amid longer-term support.

Investor Participation and Liquidity

Delivery volumes surged to 6.22 lakh shares on 18 Feb, marking a 56.8% increase over the five-day average delivery volume. This rise in delivery volume indicates stronger investor participation and conviction, possibly from long-term holders accumulating on dips or short-term traders adjusting positions. The stock’s liquidity remains adequate, with a trade size capacity of ₹4.18 crore based on 2% of the five-day average traded value, facilitating smooth execution of sizeable trades without significant price impact.

Market Positioning and Directional Bets

The surge in open interest amid falling prices typically signals fresh short positions or hedging activity. However, given the substantial rise in delivery volumes and the stock’s position above key moving averages, it is plausible that investors are building long-term positions while short-term traders are actively hedging or speculating on volatility. The large notional value in options contracts further supports the presence of complex strategies, including spreads and straddles, aimed at capitalising on anticipated price movements or volatility shifts.

HDFCAMC’s Mojo Score currently stands at 61.0, with a Mojo Grade of Hold, downgraded from Buy on 8 Jan 2026. This reflects a cautious stance amid recent price weakness and mixed technical signals. The company’s market capitalisation remains robust at ₹1,17,169.29 crore, categorising it as a large-cap stock within the Capital Markets sector. Despite the downgrade, the stock’s fundamentals and sector positioning continue to attract investor interest, as evidenced by the derivatives activity.

Comparative Sector and Market Context

Within the Capital Markets sector, HDFCAMC’s underperformance relative to the sector’s 0.60% decline and the Sensex’s 0.94% fall highlights stock-specific pressures. These may stem from profit booking or sector rotation. However, the rising open interest and volume suggest that market participants are positioning for a potential rebound or increased volatility. The stock’s ability to hold above long-term moving averages provides a technical cushion, which may attract value-oriented investors seeking entry points.

Implications for Investors

For investors, the recent surge in derivatives open interest and volume signals an important inflection point. The mixed signals from price action and technical indicators warrant a balanced approach. Those with a medium to long-term horizon may consider accumulating on dips, given the stock’s large-cap status and sector fundamentals. Conversely, short-term traders should monitor volatility and open interest trends closely to gauge momentum and potential breakout or breakdown scenarios.

Overall, the derivatives market activity around HDFCAMC reflects a nuanced market view, combining cautious optimism with hedging strategies. Investors should remain vigilant to broader market cues and sector developments while factoring in the stock’s recent downgrade to Hold.

Technical Outlook and Moving Averages

Technically, HDFCAMC’s price remains above its 20-day, 50-day, 100-day, and 200-day moving averages, indicating a generally bullish medium to long-term trend. However, the recent dip below the 5-day moving average suggests short-term weakness and possible consolidation. Traders should watch for a sustained move above the 5-day average to confirm a resumption of upward momentum. Conversely, a break below the longer-term averages could signal deeper correction risks.

Conclusion

The pronounced increase in open interest and volume in HDFC Asset Management Company Ltd’s derivatives points to active repositioning by market participants amid a challenging price environment. While the stock has experienced short-term weakness, the underlying technical support and rising delivery volumes indicate that investors are preparing for potential directional moves. The downgrade to Hold reflects caution, but the stock’s large-cap stature and sector fundamentals continue to offer opportunities for discerning investors. Monitoring open interest trends and price action will be crucial in the coming sessions to gauge the prevailing market sentiment and directional bias.
