Jakarta. Jakarta Composite Index (JCI) extended its gains at Thursday's opening, rising 14 points, or 0.26%, to 5,709 as investors weighed weaker domestic economic indicators against broadly positive regional market sentiment.

The benchmark index traded in the 5,704–5,722 range during early trade.  RTI data showed 527.37 million shares worth Rp 392.39 billion ($18.32 million) changed hands in 45,256 transactions. Advancers outnumbered decliners, with 220 stocks gaining, 143 falling, and 234 unchanged.

Phintraco Sekuritas pointed to a string of softer domestic economic data. Indonesia's S&P Global Manufacturing PMI fell to 46.9 in June 2026 from 50 in May, marking its lowest reading since June 2025 and the second contraction this year, driven by declines in new orders and export sales.

Indonesia also posted a $1.61 billion trade deficit in May, its first monthly deficit since April 2020. Exports unexpectedly declined 5.73% year-on-year, missing expectations for 6.4% growth, while imports jumped 22.16%, exceeding the 19.5% forecast, mainly due to higher oil and gas imports.

Meanwhile, annual inflation accelerated to 3.34% in June from 3.08% in May, above the 3.2% market expectation and the highest level since March, although it remained within Bank Indonesia's target range.

The increase was largely driven by higher Pertamax fuel prices following the June 10 adjustment. Core inflation also rose to 2.76% year-on-year from 2.59% in May, reaching its highest level in 38 months.

Phintraco Sekuritas also cited Fitch Ratings' assessment that Indonesia's foreign exchange reserves remain under pressure despite Bank Indonesia raising its benchmark interest rate by a cumulative 100 basis points.

"Investor sentiment remains weak due to concerns over policy credibility, fiscal discipline, and the government's export plans through Danantara Sumberdaya Indonesia (DSI)," the brokerage said.

Overnight, Wall Street closed mixed as losses in several heavyweight technology stocks outweighed broader market strength. The S&P 500 slipped 0.2% for its eighth decline in the past 11 sessions, while the Dow Jones Industrial Average edged down 13 points, or less than 0.1%. The Nasdaq Composite fell 0.7%.

Across Asia, markets were mostly higher as of 9:39 a.m. Jakarta time. Japan's Nikkei gained 1.08%, South Korea's Kospi climbed 2.67%, and Hong Kong's Hang Seng advanced 1.14%. China's Shanghai Composite was the outlier, slipping 0.81%.
