DEFINITION of Indonesia Stock Exchange (IDX) .ID

The Indonesia Stock Exchange (IDX), created by the merger of Jakarta Stock Exchange (JSX) and the Surabaya Stock Exchange (SSX), handles securities transactions in the country.   The JSX was Indonesia's first stock exchange, founded in 1912 for the interest of the Dutch East India Company. The Jakarta Stock Exchange was closed during parts of World Wars I and II. When it reopened in 1952, the only exchanged security was the Indonesian government bond. The exchange became inactive from 1956-1977, and despite being reactivated in 1977, trading activity continued to be slow, with only a few dozen companies listed.

Regulatory changes between 1988 and 1992 improved trading activity. The Exchange introduced its automatic trading system in 1995 and began to implement remote trading in 2002. In 2007, the Jakarta Stock Exchange merged with the Surabaya Stock Exchange to form the Indonesia Stock Exchange.

Emerging markets like Indonesia have their own set of additional risks for investors. Emerging markets generally do not have the level of market efficiency and strict standards in accounting and securities regulation to be on par with advanced economies (such as the United States, Europe and Japan), but emerging markets do typically have a physical financial infrastructure, including banks, a stock exchange and a unified currency.
