IDX Index

The IDX Composite Index (also known the JKSE, JCI, and JSX Composite index) is the composite index that tracks the stock performance of all the companies listed on the Jakarta Stock Exchange, now the Indonesia Stock Exchange. Formerly known as the JSX Composite, the IDX is widely used as an indicator for the strength of the Indonesian economy.

This page will give you a brief overview of the history of the IDX index, explain how the stocks it tracks are selected, and give you information about how you can invest your money in the index.

The IDX index was started in 1982 as a way of assessing the performance of all companies listed on what was then known as the Jakarta Stock Exchange. In 2007 this exchange merged with the Surabaya Stock Exchange to form the Indonesia Stock Exchange (IDX). This exchange now lists over 500 companies, all of which are included in the IDX Composite Index.

The IDX index saw a period of fast growth after the financial crash of 2007-08, rising from 1,202.07 on 27th November 2008 to the index’s all-time high of 6,660.62 on 26th January 2018. This growth then flattened out before IDX was hit hard by the economic uncertainty surrounding the COVID-19 pandemic in the early part of 2020.

The IDX tracks every stock listed on the Indonesian Stock Exchange, so the criteria for a stock being tracked by the index is that it is traded on the IDX. There are currently over 600 companies whose stocks are listed on this exchange, covering all aspects of the Indonesian economy.
