20 Issuers with the Highest Share Ownership Concentration on the IDX as of October 2026

According to data from the Indonesia Stock Exchange (IDX), during the period from April 2 to October 12, 2026, there were 80 publicly listed companies in the Indonesian capital market characterized by high shareholding concentration (HSC).

HSC refers to a situation where the ownership of a company’s shares is concentrated among a select few parties.

"This condition can limit the number of shares available to the public, which in turn affects trading liquidity and potentially increases stock price volatility," the IDX stated on its website.

"While this does not necessarily indicate any violation, stocks categorized as having high shareholding concentration serve as a signal for investors to exercise greater caution, given the risk of more significant price fluctuations," the IDX added.

Among all the companies falling into the HSC category, the highest level of shareholding concentration is found in PT Maha Properti Indonesia Tbk (MPRO), where 99.99% of the shares are collectively held by a specific group of parties.
