Under the futures and options (F&O) segment, two stocks were banned from trade on Thursday, November 9, by the National Stock Exchange (NSE). The securities banned for the F&O trade are Delta Corp and Gujarat Narmada Valley Fertilizers & Chemicals (GNFC). 

Derivative contracts of these stocks were banned as the open market interest for these securities has crossed 95% of the market-wide position limit (MWPL) set by the exchanges. The MWPL is the maximum number of contracts that can be opened at any particular time. 

GNFC was retained on the list as the open interest as a percentage of the MWPL of its F&O contracts stood at 90.2% on November 9. Delta Corp was added to the list on Thursday as the open interest of its F&O contracts reached 97.7%. 

The ban will be lifted once the position falls below 80%. Traders will get penalised for buying or selling these securities. They will be available for trading in the cash market.

The National Stock Exchange updates the list of securities on the F&O ban list daily. This list serves as a guide for traders and investors in the market. Traders who trade in indices do not encounter a situation of security ban.
