F&O trading or Futures and options trading is a popular form of trading in stock markets. It is part of the derivative markets or the secondary markets. Traders have to gain a tremendous knowledge base to successfully carry out F&O trading and know the nuances of the market to take profitable positions. There are also many terms and rules that need to be studied and understood by the traders with regards to the F&O trading, one of them being the F&O Ban.

Given below is the meaning of the F&O ban and its impact on the share prices.

What is the F&O ban and how does it apply??

In the securities market, SEBI has laid many rules for trading in the F&O market. According to these rules, at any point in time, the open interest for any security cannot cross 95% of its Market wide Position Limit (MWPL). If the security crosses this limit, it comes under the F&O ban list. 

MWPL is the maximum number of open positions allowed for any security across all the F&O contracts of such underlying security. MWLP is usually calculated to be 20% of the total shares of the company that are held by the non-promoters. Once the stock enters the F&O ban list, the traders are not allowed to take any new trading positions. The only permissible trade in such a case is to offset the open positions. There is a feature on the National Stock Exchange (NSE) which provides the facility on its trading system to display an alert when the open interest of F&O contracts in stock exceeds 60 percent of the Market Wide Position Limit (MWLP). Furthermore, these alerts are displayed in intervals of 10 minutes for the benefit of the traders.

When does the stock enter the F&O ban?

As mentioned above, every stock has a prescribed limit in the form of Market Wide Position Limit. Any stock crossing this limit in trade is banned by the stock exchange. This ban is placed only in the case of stocks so traders trading in indices do not have to worry about this ban. The exchange restricts the trading of any stock in the F&O market when that particular stock is traded beyond the 95% mark. 

Once the stock hits the 95% mark, traders are not allowed to take any new positions that are not to exit their existing position. The stock will stay in the F&O ban list till the time the excess positions are not squared off and the total open positions in the F&O market for such stock do not reach 80% of the MWLP. There is no time limit set for the open positions to come back to this level. 

What is the impact of the F&O ban on share prices?

There have been many occasions when a stock has been put in the F&O ban list by the exchange when the open positions go beyond the 95% mark. This ban is put in place to restrict excessive speculation as it can affect the market stability and loss of investor confidence. The exchange may also put a stock on the ban list to keep its volatility in check. 

A stock can be on the F&O ban list for a temporary period or permanently. When the stock crosses the Market wide Position Limit (MWPL) beyond the stipulated 95% it is put on a temporary ban list till the time it reaches the level of 80% of the MWLP. In such a case, there may or may not be a significant impact on the share prices. 

On the other hand, stock can be put on the permanent ban list if such a company has violated the rules and regulations laid down by the exchange or SEBI. Some examples of these regulations can be lack of liquidity, inadequate market capitalization, fraud by management, etc. Such a permanent ban can also impact the share prices of the banned stock (for example the ban on Satyam Computer Services where the share pieces decreased drastically).

Conclusion

Futures and options are a complex form of trading in the derivatives market that requires the traders to adhere to the various regulations set by the exchange and the regulator. These regulations are set to safeguard the interest of the investors and to protect them and the market as a whole from the perils of excessive speculations. The F&O ban list is one such regulation that is put in place to safeguard the traders. 

FAQs

When is the stock removed from the F&O ban list?

A stock is removed from the F&O ban list when the open interest of such security falls to 80%.

Can the F&O ban list include indices?

No. F&O ban list can include only stocks. This regulation is not applicable for F&O trading in indices.
