Indonesia Stock Exchange Issues Warning Over Unusual Movement in Four Stocks
Jakarta, CNBC Indonesia - The Indonesia Stock Exchange (IDX) has begun closely monitoring Unusual Market Activity (UMA) patterns for four stocks simultaneously, starting Wednesday (1/9/2026). These issuers are under surveillance due to abnormal share price increases.
The four issuers are PT Indo Acidatama Tbk (SRSN), PT Charlie Hospital Semarang Tbk (RSCH), PT Royalindo Investa Wijaya Tbk (INDO), and PT Bank Of India Indonesia Tbk (BSWD).
Citing IDX information disclosure, these stocks are exhibiting movements outside of normal patterns. This measure is taken to protect investors, particularly shareholders of the aforementioned companies.
“The announcement of Unusual Market Activity (UMA) does not necessarily indicate a violation of capital market laws and regulations,” the IDX management wrote, as quoted from its official website.
“Regarding the occurrence of UCA on SRSN shares, we wish to inform you that the Exchange is currently scrutinising the development of this stock’s transaction patterns,” it added.

With this announcement, investors are expected to pay attention to the issuers’ responses to the Exchange’s requests for confirmation, monitor issuer performance and information disclosures, re-evaluate planned corporate actions if they have not yet received General Meeting of Shareholders (RUPS) approval, and consider various future possibilities before making investment decisions.
