Under the futures and options (F&O) segment, two stocks were banned from trade on Thursday, September 28, by the National Stock Exchange (NSE). The securities banned for the F&O trade are Delta Corporation and India Cements.

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. 

The combined open interest for the derivatives contracts of Delta Corp and India Cements stood at 109.2% and 88.9%, respectively, of their MWPL on September 27. The above securities were retained on the list from Wednesday. 

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 open interest for the F&O contracts of Balrampur Chini Mills, Canara Bank, Hindustan Copper, and Indiabulls Housing Finance declined below the 80% limit. They, hence, were exited from the list on Thursday. 

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.
