Rs 840 Puts — 0.75% Below Current Price — Draw 2,789 Contracts on Hindalco Industries Ltd

Put Options Event and Cash Market Context

On 23 Mar 2026, the Rs 840 put strike saw 2,789 contracts traded, generating a turnover of approximately ₹381.28 lakhs. The open interest at this strike stands at 909 contracts, indicating that a significant portion of the traded volume represents fresh positioning rather than merely adjustments to existing positions. The expiry date for these options is 30 Mar 2026, just a week away, which adds urgency to the positioning.

The underlying stock price closed at Rs 846.45, placing the Rs 840 strike roughly 0.75% out-of-the-money (OTM). Given the stock’s recent decline of nearly 10% over four days and a 3.55% drop on the day of the put activity, the proximity of the strike to the current price is a critical factor in interpreting the intent behind this put activity — is this a directional bearish bet or a protective hedge?

Strike Price Analysis: Moneyness and Intent

The Rs 840 strike is just below the current market price, making these puts near-the-money (NTM) or slightly OTM. This strike distance is often favoured for hedging existing long positions, as it offers protection against moderate downside moves without the higher premium cost of in-the-money (ITM) puts. If the put buyers were purely bearish, one might expect more activity at strikes further below the market price, anticipating a sharper decline.

However, the stock’s recent weakness and the strike’s closeness to the current price also mean that these puts could be part of a directional bearish strategy, especially with expiry approaching. The Rs 840 strike implies a downside expectation of around 0.75% within the next week, which is modest but consistent with a cautious bearish stance or a tactical hedge against short-term volatility.

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

Put option activity can signal multiple strategies. First, the purchase of OTM or NTM puts on a falling stock often indicates bearish positioning, as traders seek to profit from further declines. Second, such puts can serve as protection for existing long holdings, especially when the stock has recently fallen sharply — a scenario that fits Hindalco’s recent price action. Third, put writing (selling puts) is a bullish strategy, where sellers collect premium expecting the stock to stay above the strike.

In this case, the relatively high number of contracts traded (2,789) compared to open interest (909) suggests fresh buying rather than put writing. The stock’s four-day decline of nearly 10% and the proximity of the strike to the current price support the view that these puts are likely bought for protection or as a cautious bearish bet rather than aggressive put selling.

Open Interest and Contracts Analysis

The ratio of contracts traded to open interest is approximately 3.07:1, indicating that the bulk of the activity is fresh rather than rollovers or closing trades. This fresh positioning at a strike close to the current price and near expiry suggests traders are actively seeking downside protection or positioning for a short-term move.

Open interest of 909 contracts is moderate, but the surge in traded contracts on the day points to a meaningful shift in sentiment or risk management. The lack of a corresponding surge in call options at similar strikes further supports the interpretation that this is not a neutral or straddle strategy but focused on downside risk.

Cash Market Context: Price Momentum and Moving Averages

Hindalco Industries Ltd has been under pressure, falling 9.73% over the last four sessions and opening down 2.2% on the day of the put activity. The stock’s intraday low touched Rs 839.1, below the Rs 840 put strike, signalling that the strike is relevant to current trading levels.

The stock trades above its 200-day moving average but remains below the 5-day, 20-day, 50-day, and 100-day moving averages. This mixed technical picture suggests a short-term downtrend within a longer-term uptrend. The Rs 840 strike is close to the recent intraday lows and may represent a tactical hedge against further short-term weakness rather than a bet on a sustained collapse — how does this technical setup influence the put activity?

Delivery Volume and Liquidity Considerations

Delivery volumes on 20 Mar rose sharply by 83.95% to 55 lakh shares compared to the 5-day average, indicating increased investor participation despite the price decline. However, the stock’s liquidity remains robust, with a trade size capacity of approximately ₹13.05 crore based on 2% of the 5-day average traded value.

The rising delivery volume amid falling prices may have prompted investors to seek downside protection through puts, especially given the stock’s large-cap status and sector volatility in Non - Ferrous Metals. The combination of active delivery participation and put buying suggests a cautious stance rather than outright bearish conviction.

Conclusion: Protective Hedging or Bearish Positioning?

The put activity at the Rs 840 strike on Hindalco Industries Ltd reflects a complex interplay of factors. The strike’s proximity to the current price, the stock’s recent sharp decline, and the surge in fresh put contracts all point to a likely protective hedging motive by investors seeking to guard against further short-term losses.

While a purely bearish interpretation cannot be ruled out given the stock’s downtrend and put strike near the money, the data does not strongly support aggressive directional bets. Instead, the put buying appears to be a measured response to recent volatility, consistent with risk management rather than outright pessimism.

With the expiry date approaching, this activity highlights the importance of short-term risk control in a volatile sector. Should investors consider similar protective strategies or view this as a signal to reassess their exposure?
