Indonesia's top ten of largest companies in terms of market capitalization took a hard blow today. Of these companies Unilever Indonesia and Bank Rakyat Indonesia were the top losers, falling 3.49 percent and 3.09 percent respectively.

Apart from Singapore's main stock index, all other indices in the Asia-Pacific fell. Japan was hit hardest and lost 3.32 percent.

The reason behind the general weak performance in Asia today is that most investors are waiting for meetings of the Federal Reserve at the end of this month and the meeting of the European Central Bank.
