Suspension of trading is also called "securities suspension". A stock exchange shall regularly or irregularly review or recheck the securities listed on the stock exchange. If a stock exchange finds that listed securities are not suitable for further listing, it may issue a notice of suspension of listing of securities and suspend its listing conditions. There is usually a prescribed time limit. After the reasons for the suspension of listed securities are eliminated, the Exchange will issue a Notice of Resumption of Listing to resume listing. If the reasons for the suspension are not eliminated after the expiration of the suspension period, the listing qualification of the suspended securities will usually be terminated.
