The strengthening index this time is mostly supported by internal sentiments, such as stable inflation rate and positive outcome of a limited Cabinet meeting held Tuesday, during which President Joko "Jokowi" Widodo expected the economy to grow by 5.6 percent in 2018 and 5.1 percent this year, Bina Artha Sekuritas senior analyst Reza Priyambada wrote in a text message.

"This sets aside several negative sentiments, such as weakening global bourses and rupiah value," he wrote.

Rupiah value against the US dollar, meanwhile, weakened slightly by six points to Rp 13,331 on Tuesday.

Mirae Asset Sekuritas Indonesia projects the index to continue its upward move to between 5,640 and 5,676 on Wednesday. (hwa)
