Sebi revises CAS rules, changes derivatives expiry settlement methodology
SEBI is in focus.
· ET Stocks, Economic Times Markets
Sebi has announced changes to the closing auction session for the equity cash market, which will begin in December 2026. The revised session will run from 3.30 pm to 3.40 pm, with specific phases for order entry. Moreover, the methodology for calculating settlement prices for derivatives contracts has been updated.
The analysis
Because the driver here is macro rather than company-specific, the read-through is to index-level positioning rather than to any single name — correlations tend to rise when the whole market faces the same signal.
Why it matters
- With SEBI involved, this carries a regulatory dimension that can outlast the immediate market reaction.
Market context
- This is a market-wide development — its reach goes beyond any single stock.
