"The BEI index fell quite sharply with share sales by foreign investors. The share sales was also reflected in the falling value of rupiah against the US dollar," Panin Sekuritas` analyst Purwoko Sartono said.
Purwoko said foreign investors sold Rp640 billion worth of shares on Wednesday.
External factor putting pressure on the regional indexes including BEI index was US failure to reach an agreement on its state budget which almost reached the ceiling.
Some US economic data being worse than expected also contributed to negative sentiment in the market, Purwoko said.
He said there was no signs that the time has been ripe for a reversal in the index movement but there is still potential buy back in short term after price fall in the past several days.
"We predict the BEI index would hover around 4,320--4,450 points on Thursday," he said.
