Under the futures and options (F&O) segment, two stocks were banned from trade on Thursday, November 30, by the National Stock Exchange (NSE). The securities banned for the F&O trade are Hindustan Copper Ltd and Manappuram Finance. 

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. 

Hindustan Copper was retained on the list as the open interest as a percentage of the MWPL of their F&O contracts stood at 96.5% on November 29. Manappuram Finance was added to the list on Thursday as the open interest of their F&O contracts reached 97%.

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, Bharat Heavy Electricals Limited (BHEL), Granules India, Hindustan Petroleum Corp, Indiabulls Housing Finance, and Zee Entertainment Enterprises Ltd (ZEEL) declined below the 80% limit. Hence, they 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.
