Mumbai, November 21, 2025 – The NSE bulk and block deal window lit up on Thursday with over ₹4,500 crore worth of trades, led by a stunning ₹2,100 crore block in edtech giant Physicswallah (Alakh Pandey-founded PW). High-frequency traders, proprietary desks, and institutional players dominated the action, while several small and mid-cap names witnessed heavy off-market transfers amid volatile sessions.
Block deals (trades above ₹10 crore) and bulk deals (over 0.5% of equity) often signal big money moves – from promoter stake sales and private equity exits to opportunistic buying by domestic funds. Thursday's data revealed sharp activity in newly listed IPO stocks, infra players, and specialty chemical names.
Top 10 Largest Bulk & Block Deals on November 20, 2025

- SBC Exports (SBC) – ₹80 crore Acme Capital Market flipped 30 lakh shares at ₹26.34-26.46.
Other notable mentions: Oriental Trimex saw ₹20+ crore churn at ₹8.50-9 levels, Fairchem Organics had a ₹56 crore block sale by 360 ONE Special Opportunities Fund, and Solex Energy changed hands worth ₹11 crore at a whopping ₹1,911 per share.
Market watchers say the Physicswallah block – coming just months after its bumper IPO – reflects continued liquidity hunting by prop firms rather than fundamental shifts. Meanwhile, aggressive buying in beaten-down infra names like Salasar and Vikran hints at bottom-fishing by smart money.
Investors should watch volume spikes and delivery percentages in these names over the next few sessions, as bulk deals often act as leading indicators for short-term swings.
