Shares of state-owned metals producer Hindustan Copper Ltd experienced severe selling pressure on August 25, 2026, following the Indian government's announcement of a stake sale through an Offer for Sale (OFS). Investors reacted swiftly to the discount offered on the floor price compared to the previous trading session, causing the stock to tumble by over 7 percent during intraday trading.
Trading Session Movements and Price Volatility
On the National Stock Exchange (NSE), Hindustan Copper shares were trading at Rs 532.70 by 12:57 pm on August 25, 2026, marking a decline of Rs 41.45 or 7.22 percent from the previous close. The trading day began with the stock opening at Rs 542 before ascending to an intraday high of Rs 551.85. However, heightened selling forced the stock down to an intraday low of Rs 529.35, demonstrating considerable price volatility.
Understanding the Floor Price Discount
The primary catalyst for the stock's slump was the government setting the OFS floor price at Rs 514 per share. This baseline valuation offered a discount of approximately 10 percent compared to Monday's closing level of Rs 573.55. When a promoter or substantial stakeholder releases equity at a significant mark-down from prevailing market valuations, short-term adjustments frequently take place as traders price in the fresh influx of share supply.
OFS Structure, Stake Dilution, and Green Shoe Option
Under the baseline terms of the transaction, the government aims to divest a 3 percent equity stake in Hindustan Copper. Institutional and non-retail bidding commenced on August 25 between 9:15 am and 3:30 pm. Retail market participants are scheduled to submit their bids on August 26. Furthermore, the government retains an additional 3 percent over-subscription or green shoe option, which, if fully exercised, could double the total stake sale to 6 percent.
Retail Reservation and Execution Mechanics
Specific allocations have been earmarked across different investor segments within the offer architecture. Ten percent of the base OFS size is reserved exclusively for retail buyers, while eligible company employees have been allocated a dedicated reservation of 25,000 shares. The divestment transaction is executed directly through the automated trading mechanism of the stock exchanges, requiring participating investors to place bids via registered broker networks.
Market Outlook and Key Takeaways
Financial market observers emphasize that the Rs 514 figure acts solely as a price floor rather than a guaranteed final allocation rate. The clearing price will ultimate reflect institutional bid density, overall demand across categories, and allotment rules. The stock's short-term trajectory following the OFS will hinge on institutional subscription levels achieved during the initial window and whether the government elects to exercise the supplementary 3 percent green shoe mechanism.
