With 657,424 inhabitants ( 2011) Riga is the largest city of the Baltic states, one of the largest cities in Northern Europe and home to more than one third of Latvia's population. The city is an important seaport and a major industrial, commercial, cultural and financial centre of the Baltic Sea region.^{[citation needed]} The city lies on the Gulf of Riga, at the mouth of the river Daugava. Riga's territory covers 307.17 km² (118.60 sq mi) and lies between 1 and 10 metres (3.3 and 33 ft) above sea level, on a flat and sandy plain.

Riga was founded in 1201 and is a former Hanseatic League member. Riga's historical centre is a UNESCO World Heritage Site, noted for its Art Nouveau/Jugendstil architecture and 19th century wooden architecture. The city will be the European Capital of Culture in 2014, along with Umeå in Sweden. The city hosted the 2006 NATO Summit, the Eurovision Song Contest 2003 and the 2006 IIHF Men's World Ice Hockey Championships. It is home to the European Union's office of European Regulators for Electronic Communications (BEREC). Riga is served by Riga International Airport, the largest airport in the Baltic states.

A stock exchange is a form of exchange which provides services for stock brokers and traders to trade stocks, bonds, and other securities. Stock exchanges also provide facilities for issue and redemption of securities and other financial instruments, and capital events including the payment of income and dividends. Securities traded on a stock exchange include shares issued by companies, unit trusts, derivatives, pooled investment products and bonds.

To be able to trade a security on a certain stock exchange, it must be listed there. Usually, there is a central location at least for record keeping, but trade is increasingly less linked to such a physical place, as modern markets are electronic networks, which gives them advantages of increased speed and reduced cost of transactions. Trade on an exchange is by members only.

The initial offering of stocks and bonds to investors is by definition done in the primary market and subsequent trading is done in the secondary market. A stock exchange is often the most important component of a stock market. Supply and demand in stock markets are driven by various factors that, as in all free markets, affect the price of stocks (see stock valuation).
