IDX Announces Shares with High Shareholding Concentration

The Indonesia Stock Exchange (IDX) and the Indonesian Central Securities Depository (KSEI) announced a list of shares with high shareholding concentration (HSC) after the market close on Thursday, 2 April 2026. Acting President Director of IDX Jeffrey Hendrik stated that the HSC announcement refers to a practice implemented in Hong Kong when addressing similar issues from global index providers. “HSC is an announcement to the public where there is concentrated share ownership among a number of shareholders,” said Jeffrey at his office in South Jakarta on Thursday, 2 April 2026. He stated that the information is provided as additional consideration for investors. According to him, inclusion of a share in the HSC list does not automatically mean a violation of capital market regulations, including free float obligations. The determination of shares in the HSC category is carried out through discussions by a joint committee of IDX and KSEI using a methodology outlined in standard operating procedures (SOP). Jeffrey explained that in Hong Kong, authorities do not take specific actions against companies announced to have high ownership concentration. In Indonesia, issuers listed in the HSC list can conduct reviews and take necessary steps to increase their investment attractiveness. Issuers can then report those efforts to IDX and KSEI for re-evaluation. If the assessment shows that the ownership concentration is no longer high, IDX and KSEI will announce the revocation of the HSC status for that issuer.
