Rs 1,650 Puts — 0.8% Below Current Price — Draw 2,112 Contracts on Sun Pharmaceutical Industries Ltd

Put Options Event and Cash Market Context

On 10 Apr 2026, Sun Pharmaceutical Industries Ltd saw significant put option activity concentrated around four strikes expiring on 28 Apr 2026. The most active were the Rs 1,660 puts with 3,749 contracts traded, closely followed by Rs 1,600 (3,699 contracts), Rs 1,700 (2,211 contracts), and Rs 1,650 (2,112 contracts). The total turnover for these strikes ranged from Rs 204.17 lakhs to Rs 451.64 lakhs, signalling substantial premium flow in the put segment.

The stock itself declined 3.34% on the day, touching an intraday low of Rs 1,643.6, and underperformed its sector by 2.52%. It traded below all major moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — indicating a sustained downtrend. Delivery volumes also fell 2.36% against the five-day average, suggesting weakening investor participation in the cash market. Is this decline signalling a deeper correction or a temporary pullback?

Strike Price Analysis: Moneyness and Distance from Underlying

The Rs 1,650 strike sits just 0.8% out-of-the-money (OTM) relative to the closing price of Rs 1,663.1, while the Rs 1,660 strike is effectively at-the-money (ATM). The Rs 1,700 strike is 2.2% in-the-money (ITM), and Rs 1,600 is 3.8% OTM. This clustering of put activity close to the current price suggests a focus on near-term downside protection or directional positioning rather than speculative deep OTM bets.

OTM puts near the money often serve as hedges for existing long positions, especially when the underlying is in a downtrend but not collapsing. Conversely, ITM puts can indicate stronger bearish conviction or part of complex spread strategies. The Rs 1,700 strike’s ITM status with 2,211 contracts traded and 1,140 open interest points to some directional bearishness or protective layering by holders of long stock or call positions.

Interpreting the Put Activity: Bearish, Hedging, or Put Writing?

Put activity is inherently ambiguous. The heavy volume at strikes close to the current price, combined with the stock’s decline and trading below all major moving averages, leans towards a bearish interpretation. Buyers of ATM and slightly ITM puts may be positioning for further downside or protecting existing long holdings from a sharper fall.

However, the presence of significant open interest at these strikes, particularly Rs 1,660 (970 OI) and Rs 1,650 (683 OI), suggests that some of this activity could be put writing, where sellers collect premium expecting the stock to hold above these levels. The Rs 1,600 strike, with 1,046 open interest and 3,699 contracts traded, also indicates active positioning that could be a mix of fresh buying and selling.

The turnover figures, especially Rs 451.64 lakhs at Rs 1,660 and Rs 431.58 lakhs at Rs 1,700, imply that premium levels are elevated, which may encourage put writing as a bullish bet on limited downside. Could this be a case where the options market is hedging while simultaneously signalling a floor?

Open Interest and Contracts Analysis

The ratio of contracts traded to open interest varies across strikes. For Rs 1,650, 2,112 contracts traded against 683 open interest, a ratio of approximately 3.1:1, indicating substantial fresh activity. Rs 1,660 shows a similar pattern with 3,749 contracts traded versus 970 open interest (3.9:1). This suggests that much of the volume is new positioning rather than mere rollovers or adjustments.

Rs 1,600 and Rs 1,700 strikes have slightly lower ratios (3.5:1 and 1.9:1 respectively), implying a mix of fresh trades and existing positions. The open interest concentration near the money supports the view that traders are actively managing risk around current price levels rather than speculating on extreme moves.

Cash Market Context: Momentum and Moving Averages

Sun Pharmaceutical Industries Ltd has been in a downtrend, trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. The stock’s 3.34% decline on 10 Apr 2026 and underperformance relative to its sector and the Sensex reinforce this bearish momentum.

Delivery volumes have also declined slightly, indicating reduced conviction among buyers. This environment typically encourages protective put buying to guard against further losses. The proximity of put strikes to the current price aligns with a strategy of hedging near-term downside risk rather than speculative deep OTM puts that would signal panic selling.

The Rs 1,650 and Rs 1,660 strikes roughly correspond to technical support zones just below recent price levels, consistent with traders seeking to limit losses if the stock tests these areas. Is this a tactical hedge or a signal of deeper weakness?

Delivery Volume and Quality of Participation

On 9 Apr 2026, delivery volume was 22.36 lakh shares, down 2.36% from the five-day average. This decline in delivery participation amid falling prices suggests that the recent sell-off may lack strong conviction from long-term holders, possibly prompting some investors to seek downside protection through puts.

Lower delivery volumes during a decline often indicate that short-term traders or option players are more active than fundamental buyers or sellers, which can increase volatility and option premium levels. This dynamic supports the interpretation that the put activity is partly hedging existing positions rather than purely directional bearish bets.

Conclusion: Protective Hedging with a Bearish Underpinning

The put option activity on Sun Pharmaceutical Industries Ltd on 10 Apr 2026 reflects a nuanced picture. The concentration of contracts near the money, combined with the stock’s downtrend and weak delivery volumes, suggests that much of the put buying is protective hedging by investors seeking to limit losses amid a bearish environment.

At the same time, the sizeable open interest and turnover at ITM and ATM strikes indicate some directional bearish positioning or layered risk management strategies. Put writing activity, while present, appears secondary given the elevated premiums and fresh positioning ratios.

Overall, the options market seems to be balancing caution with measured risk-taking rather than signalling outright panic or capitulation. Should investors consider this a warning sign or an opportunity to reassess their exposure?
