BRI Danareksa Sekuritas analyst Reza Diofanda assesses that the index’s movement in today’s trading will still be influenced by escalating tensions in Iran. This has caused oil and gas prices to rise, prompting foreign investors to shift their assets to safe-haven instruments. This was evident in Thursday’s trading (26/3/2026), with the JCI correcting 1.89% to 7,164. The net foreign sell of Rp1.93 trillion is considered due to profit-taking actions by investors amid geopolitical uncertainty, particularly regarding US-Iran ceasefire negotiations that show no signs of progress. “From a technical perspective, the JCI is expected to move in a limited range in the short term, with support at 7,100 and resistance at 7,300–7,340. External sentiments, including rising energy prices such as oil and gas, as well as selling pressure from foreign investors, remain the main factors holding back the index’s potential strengthening,” Reza stated in his daily research on Friday (27/3/2026).
