Johannesburg Stock Exchange (JSE)

About the Johannesburg Stock Exchange :

The Johannesburg Stock Exchange lists more than 400 companies and has market capitalization of over $182 billion, making it the largest exchange in Africa and among the top ten largest in the world. The exchange trades shares for a wide variety of industries, with the largest portion of market capitalization coming from the mining industry. The JSE just recently became a publicly held company in July or 2005.

The JSE lists shares on two separate markets, the Mainboard and AltX. The requirements for listing on the Mainboard are strict, while the AltX lists smaller companies who fail to meet the Mainboard criteria. As a new branch of the JSE, AltX companies currently make up a very small portion of JSE listings.

The exchange is fully electronic, using the JET System (Johannesburg Equities Trading). This is an order-based system, whereby trades are automatically executed when matching buy and sell prices are found.
