Helsinki Stock Exchange (Nasdaq Helsinki)

History and development

The exchange opened its doors on 7 October 1912 and operated for many decades as a local, member-driven market. In the 1980s the organization moved toward a more formal corporate structure and broadened ownership to include banks, trading firms and industrial companies. Over subsequent decades it became part of regional consolidation among Nordic exchanges and now functions within the Nasdaq Nordic group after integration with OMX and later Nasdaq.
