Nifty expiry and CAS expected to intensify intraday volatility

2026-09-29 · 1 source · Mint Markets

In short

Nifty is facing both weekly and monthly options expiry today, and the new closing auction session may make price swings bigger.

That can make the last part of trading more unstable for investors and traders. The report does not say which stocks will move the most.

What the reporting says

Nifty is set for both weekly and monthly options expiry, and the introduction of the Closing Auction Session is expected to heighten volatility in today’s trading session. The reporting points to sharper price swings and a closer look at market behaviour, but it does not specify which stocks or sectors will move most. The immediate consequence is higher trading uncertainty around the session close.

Why it matters

The trading session is expected to be more volatile because Nifty has both weekly and monthly expiry on the same day and the Closing Auction Session is now in play. This can affect traders, index participants and short-term strategies near the close. The source does not identify a specific stock catalyst, a confirmed market outcome, or any numerical forecast for moves.
