9 Listed Companies with High Shareholding Concentration on the IDX
The Indonesia Stock Exchange (IDX) and the Indonesian Central Securities Depository (KSEI) have released a list of listed companies with high shareholding concentration or high shareholding concentration (HSC). HSC is a condition where the majority of a company’s shares are owned by a few parties.
Acting President Director of IDX Jeffrey Hendrik stated that the HSC announcement refers to a practice implemented in Hong Kong when facing similar issues from global index providers. “HSC is a public announcement where there is concentrated share ownership among a number of shareholders,” said Jeffrey in Jakarta on Thursday, 2 April 2026.
According to Jeffrey, this information is provided as additional consideration for investors. He stated that the announcement does not necessarily indicate a violation of capital market regulations, including free float provisions.
