🚘 Tata Motors Demerger: Key F&O Impact
What’s Happening:
Tata Motors is undergoing a Scheme of Arrangement (Demerger) as per NSE Circular NSE/FAOP/70615 dated Oct 3, 2025.
Key Dates:
🗓 Ex-Date / Effective Date: 14th Oct 2025 (Tuesday)
🔚 Early Expiry of Existing F&O Contracts: 13th Oct 2025 (Monday)
(All contracts expiring on Oct 28, Nov 25 & Dec 30, 2025, will now expire early)
🆕 Fresh F&O Contracts: Will be introduced from 14th Oct 2025 based on price discovered in the Special Pre-Open Session (SPOS).
Why It Matters:
This is similar to the earlier Tata Motors DVR merger adjustment — positions in F&O will be settled early, and new contracts will trade under the post-demerger price structure. Traders holding Tata Motors futures/options should square off or roll over before 13th Oct to avoid delivery or adjustment risks.
What to Watch:
SPOS price discovery on 14th Oct
Impact on open interest & volatility in Tata Motors F&O
