Nasdaq Helsinki

Nasdaq Helsinki is the Finnish securities exchange headquartered in Helsinki. It traces its origin to the Helsinki Stock Exchange, whose first recorded transaction took place on 7 October 1912 while Finland was still a Grand Duchy within the Russian Empire. The exchange developed through periods of wartime expansion, political upheaval, Finnish independence, civil conflict, economic crises, market booms and technological change. Its historical identity is therefore closely connected with the development of Finland’s capital markets and the financing of Finnish companies. For much of its early existence, the exchange operated as a relatively informal financial association. In 1984 it was reorganized as a cooperative, with ownership distributed primarily among banks, brokers, companies and other associations. The exchange modernized its trading infrastructure over time. In 1990, trading moved to HETI, the Helsinki Stock Exchange Automated Trading and Information System. The electronic platform replaced the earlier electromechanical trading system and allowed remote participants to trade on terms more comparable with those available to members physically present in the exchange. The institution underwent a series of structural changes during the 1990s. It became a limited liability company in 1995 and subsequently combined with Finnish clearing and securities-registration organizations. In 1997 and 1998 it acquired and integrated Finland’s derivative exchanges, creating the broader HEX structure. The organization also expanded its regional presence through majority investments in the Tallinn Stock Exchange and the Riga Stock Exchange in 2001 and 2002. A decisive transformation occurred in September 2003, when HEX Plc merged with OM AB, the owner of the Stockholm Stock Exchange. The resulting group was initially known as OM HEX and was renamed OMX the following year. After Nasdaq acquired OMX in February 2008, the Finnish market was successively branded Nasdaq OMX Helsinki and then Nasdaq Helsinki. It is now one of the national marketplaces operated within Nasdaq Nordic, alongside the exchanges in other Nordic and Baltic countries. Nasdaq Helsinki provides a regulated marketplace for the trading and listing of Finnish equities and other securities. Its activities are supported by Nasdaq Nordic’s common trading, market-data and market-infrastructure framework, while Finnish market participants and issuers remain associated with the Helsinki venue. The exchange serves listed companies seeking access to public capital, institutional and retail investors, brokers, market makers and other financial-market intermediaries. Its historical derivatives activities were integrated into the broader exchange structure rather than remaining a separate Finnish exchange brand. The OMX Helsinki 25, commonly called OMXH25, is the leading share index associated with the venue. It is a market-value-weighted index covering 25 of the most-traded shares listed on Nasdaq Helsinki and was previously known as HEX25. The exchange’s normal trading session is described as running from 10:00 a.m. to 6:30 p.m. on weekdays and excluding weekends and exchange-declared holidays. Nasdaq Helsinki is best understood not as an independent global exchange group, but as the Finnish national market within the integrated Nasdaq Nordic platform.

The Helsinki Stock Exchange was established in 1912 during the period when Finland was an autonomous Grand Duchy of the Russian Empire. Its first transaction was recorded on 7 October of that year. During the First World War, activity and the number of companies increased sharply, partly because of wartime demand connected with the Russian Empire. Over subsequent decades, the market experienced alternating expansion and contraction as a result of war, Finnish independence, the Finnish Civil War, economic crises, speculative cycles and advances in trading technology. The exchange remained a relatively informal financial association until 1984, when it was reorganized as a cooperative. Its members and owners included banks, brokers, companies and associations. A major technological milestone followed on 1 April 1990, when HETI became the exchange’s electronic trading system. HETI replaced the electromechanical system introduced in 1935 and made it possible for traders outside the exchange floor to submit transactions remotely. In autumn 1995 the cooperative was converted into a limited liability company named Helsingin Arvopaperipörssi. During the following period, the exchange combined with Finnish clearing and securities-depository organizations. It also acquired Finland’s two derivative exchanges in 1997 and 1998. These transactions broadened the organization beyond a traditional equity marketplace and helped form the HEX structure. In November 1998, HEX merged with Arvopaperikeskus to create Helsinki Exchanges Group Plc; the group adopted the shorter name HEX Plc in spring 2001. HEX then pursued regional consolidation. In 2001 and 2002 it acquired majority holdings in the Tallinn Stock Exchange and the Riga Stock Exchange, linking the Finnish market more closely with the emerging Baltic exchange network. On 3 September 2003, HEX Plc merged with OM AB, the company that owned the Stockholm Stock Exchange. The combined organization was initially called OM HEX and was renamed OMX in 2004. Nasdaq acquired OMX in February 2008. The Finnish market consequently became known as NASDAQ OMX Helsinki and later Nasdaq Helsinki. The exchange is now operated within Nasdaq Nordic, an integrated family of Nordic and Baltic marketplaces. Nasdaq Helsinki retains its role as the Finnish listing and trading venue while sharing group-level technology, market-data arrangements and operational infrastructure. The venue’s principal market functions include listing and trading securities, providing issuer services and distributing market information. The OMX Helsinki 25, or OMXH25, is its best-known benchmark. The index is market-value weighted and comprises 25 of the most-traded shares on the exchange; it was formerly called HEX25. The exchange’s published normal trading hours are 10:00 to 18:30 on weekdays, excluding weekends and exchange holidays.
