Which stocks are eligible for CAS?

The new closing auction session (CAS) will only apply to stocks that trade in the Futures & Options (F&O) market.

Here are lists of stocks which are eligible for the CAS.

Segments not affected right now:

  • Non-F&O stocks: Stocks without F&O contracts will continue using the traditional 30-minute average price method (VWAP) to set their daily closing price.
  • Stocks exiting F&O: If a stock is removed from the F&O market, it will automatically switch back to the old 30-minute average method.
