The Oslo Stock Exchange (Norwegian: Oslo Børs) (OSE: OSLO) serves as the main market for trading in the shares of Norwegian companies. It opens at 9:00am and closes 4:30pm local time (CET). In additional to a wide range of domestic companies, the OSE attracts a lot of international companies within petroleum, shipping and other related areas.

The exchange has pre-market sessions from 08:15am to 09:00am, normal trading sessions from 09:00am to 04:20pm and post-market sessions from 04:20pm to 04:30pm on all days of the week except Saturdays, Sundays and holidays declared by the Exchange in advance.[2]


The Oslo Stock Exchange started life as Christiania Børs in 1819. In the beginning, there was no organized listing or stock exchange; the Børs served as a meeting place for investors auctioning ships, shares in ships, commodities, and foreign currencies. Stocks and bonds only started trading on the exchange in 1881.

In 1988, the exchange introduced an electronic trading support system, and replaced the old auction model with continuous trading of listed shares throughout the day. Trading became fully electronic in 1999 and the trading floor was discontinued.
