The index of the Indonesian Stock Exchange opened 11.75 points or 0.27 percent lower at 4,407.01 points.
The index of 45 most liquid stocks also fell 0.41 percent to 738.71 points.
Chief researcher of Trust Securities, Reza Priyambada, said the regional market declined on the Fed cutting its financial stimulus.
"The market in Asia weakened after the release of the results of the Federal Open Market Committee (FOMC) meeting last week trimming the Feds monthly stimulus to US$65 billion.
Meanwhile, the domestic market players are awaiting the release of the countrys macro economic data by the Central Statistic Agency (BPS) this week.
Head of Research of Valbury Asia Securities, Alfiansyah, said at the start of the Feds cutting its stimulus investment in developing countries would be less attractive.
"At least that is the assumption of the majority of global investors," he said.
He said the key factor to calm down the market players is rupiah stability that should be protected by the government.
Rupiah stability would provide a positive sentiment to bring the BEI index to a positive area this week, he added.
Regional markets such as Hang Seng recorded a 0.48 percent fall in index to 22,141.61 points with Nikkei index down 1.43 percent to 14,701.19 and that of Straits Times down 0.98 percent to 2,997.66.(*)
