This is in addition to over 30 companies that were delisted by NSE previously.
In a circular today, the National Stock Exchange said it has "decided to delist (withdraw the admission to dealings in) equity shares of the following (39) companies with effect from March 24, 2017 as per Chapter V of Sebi (Delisting of Equity Shares) Regulations, 2009".
Chapter V deals with compulsory delisting. The market regulator Sebi has been pushing for delisting of over 4,200 listed firms whose shares are not being traded.
In April, an NSE public notice had named 80 companies for compulsory delisting as trading in shares of these entities had been suspended over a long period of time.
