History
The Stockholm Stock Exchange was acquired by futures exchange OM in 1998. After OM merged with the Helsinki Stock Exchange to form what is now OMX in 2003, the Stockholm and Helsinki exchanges' operations were merged. Since 2008, the Stockholm Stock Exchange has been part of Nasdaq, Inc. (formerly called Nasdaq OMX Group) and its Nasdaq Nordic markets. As of October 2014, the exchange operated under the legal name Nasdaq OMX Stockholm AB (renamed Nasdaq Stockholm AB in 2015).

Prior to the introduction of electronic trading on 1 June 1990, all trading was conducted on the floor of the Stockholm Stock Exchange Building.

Its normal trading sessions are from 09:00 to 17:30 on all days of the week except Saturdays, Sundays and holidays declared by the Exchange in advance.
