Put Option Trading Highlights
Data from recent trading sessions reveals that BSE Ltd's put options with a strike price of ₹2600 have emerged as the most actively traded contracts. On the expiry date of 30 December 2025, a total of 3,436 contracts exchanged hands, generating a turnover of approximately ₹1000.9 lakhs. The open interest for these contracts stands at 2,291, indicating a substantial build-up of positions that could influence price movements as expiry approaches.
The underlying value of BSE shares at the time of this activity was ₹2599.7, closely aligned with the strike price of the put options. This proximity suggests that market participants are positioning themselves around a critical price level, potentially anticipating volatility or downside risk in the near term.
Price and Market Performance Context
On 16 December 2025, BSE shares recorded a one-day return of -1.58%, underperforming both its sector and the broader Sensex index, which posted declines of -0.35% and -0.37% respectively. This relative weakness may be contributing to the increased interest in put options as investors seek to hedge against further downside or express bearish views.
Technical indicators present a mixed picture. The stock's price remains above its 100-day and 200-day moving averages, suggesting a longer-term support base. However, it trades below its shorter-term moving averages of 5-day, 20-day, and 50-day, signalling recent downward momentum. Such divergence often prompts market participants to adopt protective strategies, including put option purchases.
Investor Participation and Liquidity
Investor engagement in BSE shares has shown signs of strengthening. Delivery volume on 15 December 2025 reached 14.25 lakhs, marking a 9.43% rise compared to the five-day average delivery volume. This uptick in delivery volume indicates a higher level of genuine investor interest rather than speculative trading.
Liquidity remains adequate for sizeable trades, with the stock's traded value averaging around ₹27.96 crores over five days. This level of liquidity supports the active options market and facilitates efficient price discovery for both the underlying shares and derivative contracts.

Implications of Put Option Activity
The concentration of put option contracts at the ₹2600 strike price, just below the current market price, suggests that investors are either hedging existing long positions or speculating on a potential decline. Put options serve as insurance against falling prices, and the sizeable open interest indicates that a significant number of market participants are preparing for downside risk or increased volatility.
Expiry patterns also play a crucial role in options trading dynamics. With the 30 December 2025 expiry approaching, traders often adjust their positions to manage risk or capitalise on expected price movements. The elevated turnover and open interest in BSE's put options highlight the stock as a focal point for such strategic positioning.
Sector and Market Capitalisation Context
BSE Ltd operates within the Capital Markets industry and sector, with a market capitalisation of approximately ₹1,07,889 crores, categorising it as a mid-cap stock. Its performance relative to the sector and broader market indices is a key consideration for investors assessing risk and opportunity.
The stock's recent underperformance compared to the sector and Sensex may be influencing the increased demand for downside protection through put options. This behaviour aligns with broader market trends where investors seek to mitigate exposure amid uncertain or weakening market conditions.
