Reza Diofanda, an analyst at BRI Danareksa Sekuritas, noted that today’s market is closely anticipating the results of Bank Indonesia’s (BI) Board of Governors’ Meeting (RDG), where the central bank is widely projected to maintain its interest rate at 4.75%. The prevailing weakness of the rupiah is also considered a significant market sentiment influencing trading activities today.
He predicted that the IHSG would test a resistance level at the 9,150 area and find potential support around the 9,100 mark, offering key technical insights for investors navigating the current market landscape.
“Additional catalysts stemming from government policies in the textile, commodity, waste-to-energy, and banking sectors could emerge as thematic drivers that further propel price movements,” he elaborated in research published on Tuesday (January 20, 2026), pointing to potential long-term growth sectors.
Fanny Suherman, Head of Retail Research at BNI Sekuritas, reported that yesterday the IHSG closed up 0.64%, yet this was accompanied by a foreign net sell of approximately Rp543 billion. The stocks most heavily offloaded by foreign investors included BBCA, GOTO, TLKM, ARCI, and INDY, indicating a shift in foreign capital allocation.
“The IHSG has the potential to continue its ascent today as long as it firmly stays above 9,100, with immediate support levels identified between 9,040 and 9,100, and resistance expected between 9,170 and 9,200,” she explained, providing a technical outlook for the index’s trajectory.
For today’s trading, BNI Sekuritas recommended investors monitor stocks such as RATU, BUMI, PGAS, CPRO, ADRO, and OASA as potential trading ideas, suggesting opportunities within specific companies.
