Nasdaq Copenhagen
Nasdaq's stock exchange in Denmark
Last updated August 31, 2026
Overview
Nasdaq Copenhagen is a stock exchange under Nasdaq Inc., formerly known as the Copenhagen Stock Exchange, providing trading services for stocks, bonds, and other securities.
History
The Danish exchange now branded Nasdaq Copenhagen developed from the Copenhagen Stock Exchange, historically known in Danish as Københavns Fondsbørs and also referred to as the CSE. It serves as an organized marketplace for Danish securities, including shares, bonds, treasury bills, notes, financial futures and options. The supplied reference material does not establish a precise original founding year, so the institution's founding date is left unspecified. A major structural change took place in 1996, when the exchange was converted into a limited company. Its share capital was distributed in a 60-20-20 ratio among exchange members, issuers of shares and issuers of bonds. This arrangement connected the exchange's ownership structure with the principal groups using and supplying its market infrastructure. In 1997, FUTOP Clearing Center A/S became a wholly owned subsidiary. FUTOP functioned as the Danish derivatives market and issued, cleared and guaranteed futures and options linked to shares, indices and interest-rate products. Its products could be traded electronically, extending the exchange's role beyond cash securities into derivatives and associated risk-management instruments. Nordic cooperation expanded in 1998, when the Copenhagen Stock Exchange and Stockholmsbörsen created the NOREX Alliance. The alliance represented an effort to build a more integrated Nordic securities market. The subsequent corporate history of the regional market infrastructure led to the 2003 merger of OM AB and HEX plc, forming OMX. In February 2008, OMX became part of Nasdaq, Inc., which at that time used the name NASDAQ OMX Group. Nasdaq Copenhagen is now one of the exchanges within Nasdaq Nordic. The exchange has also maintained a role in Danish market benchmarking. The C25 Index is a market-value-weighted index comprising 25 Danish blue-chip companies and was launched for futures and options trading. Historical index products included the KFX Index, associated with growth-oriented companies in medical, telecommunications, biotechnology and information-technology sectors, and the KAX Index, an all-share index introduced in 2001 to replace an earlier all-share index. The KAX methodology followed the Global Industry Classification Standard. Nasdaq Copenhagen's normal trading hours are described as 09:00 to 17:00 on weekdays, excluding weekends and holidays declared by the exchange. Its current identity combines the local function of Denmark's principal securities marketplace with the technology, operating model and regional connectivity of Nasdaq Nordic. The available material does not identify current executives, detailed ownership percentages, financial results or specific recent corporate campaigns.
