The Indonesia Stock Exchange (IDX) is examining three stocks after detecting signs of unusual trading. They are PT Asian Isuzu Casting Center Tbk (CASA), PT Fuji Finance Indonesia Tbk (FUJI) and PT Nusanrao Sinergi Sejahtera Tbk (NSSS).

A 45-day target and a pledge of transparency

IDX President Director Jeffrey Hendrik said the exchange's surveillance team is conducting an in-depth examination of the three stocks, with the process targeted for completion within 45 days. "Our target is for the results to be announced within 45 days," Jeffrey said at the IDX building in South Jakarta on Tuesday (10/11/2026). He added that details of the examination cannot yet be shared because the investigation is ongoing.

Jeffrey stressed that announcing the investigation status early is part of the exchange's commitment to greater transparency and investor protection. The IDX will tell the public from the outset whenever it finds signs of price manipulation or attempts at it.

The examination could widen

The IDX also left room to extend the examination to other stocks. "Oh, it can, very much so," Jeffrey said. According to him, the surveillance team will keep monitoring trading activity and will make another public announcement if early indications emerge.

Details of each examination

Based on the IDX announcement, the examination of NSSS followed transactions between 1 December 2025 and 30 October 2026 by 19 investors through 15 exchange members (AB), accounting for about 52% of total trading.

For FUJI, the examination is based on transactions from 2 March to 30 October 2026 by 16 investors through 10 exchange members, contributing about 87% of total trading.

CASA is being examined over transactions from 26 October to 2 November 2026 by 6 investors through 6 exchange members, contributing about 98% of total trading.

In all, 41 investors and 31 exchange members are covered by the examination of trading in CASA, FUJI and NSSS.

No violation alleged yet

The examination is one of the IDX's mandates in carrying out its duties of trading surveillance, investor protection and keeping trading orderly, fair and efficient. Even so, the IDX has not determined any alleged violation from its examination of the three issuers. In its announcement on Friday (6/11/2026), the exchange asked the parties concerned to keep paying attention to the disclosures made by the company.
