Jakarta. Indonesian stocks opened higher on Monday, gaining 15 points, or 0.26%, to 6,109 as investors weighed domestic market transparency measures against renewed geopolitical tensions and a packed week of global economic releases.

Jakarta Composite Index moved between 6,109 and 6,128 in early trading. Around 1.09 billion shares had changed hands, with a total transaction value of Rp 244.14 billion ($13.64 million) across 51,878 transactions.

A total of 294 stocks advanced, 147 declined and 250 remained unchanged.

Phintraco Sekuritas said the Indonesia Stock Exchange (IDX) and the Indonesia Central Securities Depository (KSEI) had expanded shareholder ownership data to include 39 investor classifications and types, with additional information distinguishing domestic and foreign ownership to strengthen market transparency.

The two institutions have also expanded the High Shareholding Concentration (HSC) list to cover stocks with market capitalizations above Rp 5 trillion.

“This could potentially increase selling pressure on stocks included on the list in the short term,” Phintraco Sekuritas said.

Overseas, Wall Street closed higher on Friday, supported by gains in technology stocks, slightly lower oil prices and optimism surrounding the quarterly earnings season and growth prospects for the artificial intelligence (AI) sector.
