IDX Releases List of High Shareholding Concentration Stocks, Including BREN, DSSA, and LUCY
Bisnis.com, Jakarta — The Indonesia Stock Exchange (IDX) has released data on High Shareholding Concentration (HSC), or stocks with high ownership concentration. Conglomerate stocks such as PT Barito Renewables Energy Tbk. (BREN) to PT Dian Swastatika Sentosa Tbk. (DSSA) appear on this list.
Based on the announcement signed by IDX Director Kristian Manullang and KSEI Director Eqy Essiqy, this HSC announcement does not necessarily indicate any violation in the capital market sector.
“This HSC announcement does not necessarily indicate a violation of applicable laws and regulations in the capital market sector,” stated Kristian and Eqy on Thursday (2 April 2026).
Kristian and Eqy explained that based on the methodology for determining High Shareholding Concentration on the share ownership structure in the form of Warkat and Non-Warkat shares as of 31 March 2026, BREN shares are owned by certain shareholders who collectively control 97.31% of the total BREN shares in Warkat and Non-Warkat form.
On the other hand, DSSA shares are owned by certain shareholders who collectively control 95.76% of the total DSSA shares in Warkat and Non-Warkat form.
Besides these two conglomerate stocks, other stocks that also fall into the HSC category include RLCO with 95.35% HSC, ROCK with 99.85%, MGLV with 95.94%, and IFSH with 99.77%. Then SOTS with 98.35%, AGII with 97.75%, and LUCY with 95.74%.
Previously, the Acting Executive Head of Capital Market, Derivative Finance, and Carbon Exchange Supervision, Hasan Fawzi, explained that to increase transparency, OJK and SROs are opening up High Shareholding Concentration (HSC) data. According to Hasan, this HSC data can be used by investors as an early warning to make decisions.
“So it’s not because of a specific violation, but information will be open for the list of stocks that are confirmed to have high concentration or ownership limited to just a few parties,” said Hasan.
The Acting President Director of IDX, Jeffrey Hendrik, explained that this policy adopts best practices that have been implemented by the Hong Kong exchange. The HSC announcement aims to provide information to the public if there is concentrated share ownership of an issuer by certain parties.
“This announcement is intended to increase transparency for investors in making investment decisions,” concluded Jeffrey during a presentation at the Indonesia Stock Exchange Building, Jakarta, on Thursday (2 April 2026).
Jeffrey stated that the inclusion of a stock on the HSC list does not necessarily indicate a violation of capital market rules.
The status is purely providing information to investors regarding the very tight ownership structure in a particular issuer.
