JSE South Africa: the Johannesburg exchange and the All Share
Understanding the JSE All Share index, a market anchored in mining and banks, and how international investors reach Johannesburg.
The Johannesburg Stock Exchange (JSE) is the oldest exchange in Africa and the largest by combined market value. It has traded since 1887 and is now a fully electronic market.
Its headline gauge is the JSE All Share Index, which spans virtually the whole listed market. The index is historically weighted towards mines, platinum, gold and diversified resources, plus a handful of large banks and retailers, and it moves with the global commodity cycle and the rand (ZAR).
Because it is large, liquid and internationally recognised, the JSE is the practical route to diversified exposure to sub-Saharan listed equities. The concentration in resources and a few financials remains its defining feature.
In addition to ordinary listings, the JSE keeps specialist gold, platinum and resource listings designed for a resource-driven economy. Dual-listing and new issuances continue to add breadth.
