Jakarta. Jakarta Composite Index (JCI) edged lower by 2.31 points, or 0.03%, to close at 8,271 on Friday, as external pressures weighed on sentiment ahead of the weekend.

The benchmark moved within a range of 8,236 to 8,328 during the session. Trading activity remained heavy, with volume reaching 45.36 billion shares and turnover at Rp 20.13 trillion ($1.19 billion), across more than 2.89 million transactions. A total of 267 stocks advanced, 381 declined, and 171 were unchanged.

Pilarmas Investindo Sekuritas said the slight pullback was driven largely by global sentiment.

On the gainers board, Bersama Zatta Jaya (ZATA) jumped 34.71%, Trisula Textile Industries (BELL) climbed 23.08%, Sekar Bumi (SKBM) rose 24.82%, and Samator Indo Gas (AGII) surged 24.80%.

Meanwhile, Indospring (INDS) fell 14.98%, Rockfields Property Indonesia (ROCK) dropped 14.95%, Raja Roti Cemerlang (BRRC) slid 14.29%, and Cipta Perdana Lancar (PART) declined 14.95%.

From the domestic front, Pilarmas noted that Indonesia and the United States have officially signed a reciprocal tariff agreement setting US tariffs at 19%, represented by Indonesia’s Coordinating Minister for Economic Affairs and the US Trade Representative.

“The agreement will certainly provide certainty for business players and investors, but there has been no official explanation on when the tariff will take effect,” Pilarmas wrote in its research note on Friday.

Externally, Asian equities came under pressure amid rising US military deployments in the Middle East. Markets are assessing geopolitical risks after US President Donald Trump set a 10- to 15-day deadline for talks on a nuclear deal with Iran.

“The market views President Donald Trump’s deadline as an indication of how the US is pressuring Iran in the negotiations,” Pilarmas said.

The brokerage added that the US has carried out its largest military deployment in the Middle East since the 2003 Iraq invasion, raising prospects of broader and more sustained operations.

“This increases the risk that a US-Iran conflict could prompt Iran to restrict traffic through the Strait of Hormuz, a vital corridor for crude oil exports from the region,” it said.

In regional markets, shares were mixed. Japan’s Nikkei 225 fell 1.1% to 56,825, Hong Kong’s Hang Seng declined 0.8% to 26,481, while South Korea’s Kospi jumped 2.3% to a fresh record of 5,808.

Overnight on Wall Street, the S&P 500 slipped 0.3%, the Dow Jones Industrial Average lost 0.5%, and the Nasdaq Composite fell 0.3% to 22,682.
