Open Interest and Volume Dynamics
On 4 February 2026, HDFC AMC's open interest (OI) in derivatives rose sharply by 3,673 contracts, a 12.34% increase from the previous day's 29,764 to 33,437. This rise in OI was accompanied by a substantial volume of 15,650 contracts traded, indicating heightened activity among traders and investors. The futures segment alone accounted for a value of approximately ₹47,323 lakhs, while the options segment's notional value stood at a staggering ₹8,154.86 crores, culminating in a total derivatives value of ₹48,608 lakhs.
The underlying stock price closed at ₹2,733, having touched an intraday high of ₹2,745, marking a 2.76% gain on the day. This price action, combined with the OI increase, suggests that market participants are positioning for further upside in the near term.
Price Performance and Technical Strength
HDFC AMC has demonstrated robust price momentum, outperforming its sector by 1.69% on the day and delivering a 2.58% gain compared to the sector's 0.92% and Sensex's modest 0.17% returns. The stock has recorded gains for three consecutive sessions, accumulating an impressive 11.36% return over this period. Notably, it is trading above all key moving averages – 5-day, 20-day, 50-day, 100-day, and 200-day – underscoring a strong technical uptrend.
Investor participation has also surged, with delivery volumes on 3 February reaching 16.14 lakh shares, a 79.59% increase over the five-day average delivery volume. This rise in delivery volumes indicates genuine buying interest rather than speculative trading, reinforcing the bullish outlook.

Market Positioning and Directional Bets
The surge in open interest alongside rising volumes typically signals fresh positions being taken by market participants. In HDFC AMC's case, the increase in OI by over 12% suggests that traders are either adding to existing long positions or initiating new bullish bets through futures and call options. The substantial notional value in options, exceeding ₹8,154 crores, points to significant hedging and speculative activity, with a probable skew towards bullish strategies given the stock’s recent price appreciation.
Moreover, the stock’s liquidity profile supports sizeable trades, with a 2% threshold of the five-day average traded value allowing for trade sizes up to ₹7.85 crores without significant market impact. This liquidity encourages institutional participation, which often drives sustained price trends.
Fundamental and Rating Overview
HDFC Asset Management Company Ltd operates within the capital markets sector and is classified as a mid-cap stock with a market capitalisation of ₹1,17,360.81 crores. Despite its recent strong performance, the company’s MarketsMOJO score currently stands at 55.0, reflecting a Hold rating. This represents a downgrade from a previous Buy rating issued on 8 January 2026, signalling a more cautious stance by analysts amid evolving market conditions.
The market cap grade of 2 further indicates moderate size and liquidity relative to larger peers. Investors should weigh the technical strength and rising open interest against this tempered fundamental outlook when considering exposure.

Implications for Investors
The combination of rising open interest, strong volume, and positive price momentum suggests that HDFC AMC is currently in a phase of accumulation by market participants. The stock’s ability to outperform its sector and maintain gains above key moving averages lends credence to a bullish near-term outlook. However, the Hold rating and recent downgrade by MarketsMOJO counsel prudence, as valuation concerns or sector-specific risks may temper further upside.
Investors should monitor open interest trends closely, as a sustained increase accompanied by rising prices typically confirms a strong bullish trend. Conversely, if open interest declines or price momentum falters, it may signal profit-taking or a shift in market sentiment. Given the stock’s liquidity and active derivatives market, tactical trading strategies such as spreads or protective puts could be considered to manage risk.
Sector and Market Context
Within the capital markets sector, HDFC AMC’s performance stands out amid a generally subdued Sensex environment, which posted a marginal 0.17% gain on the same day. The sector’s 0.92% return pales in comparison to HDFC AMC’s 2.58% daily gain, highlighting the stock’s relative strength. This divergence may attract further investor interest, particularly from those seeking mid-cap growth opportunities in financial services.
Overall, the derivatives market activity in HDFC AMC reflects a growing conviction among traders and investors that the stock is poised for further appreciation, supported by solid fundamentals and technical indicators.
Conclusion
HDFC Asset Management Company Ltd’s recent surge in open interest and volume signals a meaningful shift in market positioning, with participants increasingly betting on continued price gains. While the stock’s technical indicators and liquidity profile support this bullish stance, the Hold rating and recent downgrade advise a balanced approach. Investors should remain vigilant to changes in open interest and price action to capitalise on opportunities while managing downside risks effectively.
