Asian markets were up due to popular Chinese stocks, particularly mining and infrastructure stocks. Japan's Nikkei index, on the contrary, was down due to the appreciating yen after Japan's central bank announced it would not add more monetary stimulus to boost the economy.

Generally rising Asian stocks were seemingly the only reason why the IHSG managed to climb 0.29 percent to 4,910.29 points today (21/05). Negative market sentiments were caused by the depreciating Indonesian rupiah exchange rate and declining foreign net buying.

The rupiah depreciated 0.16 percent to IDR 11,509 per US dollar according to the Bloomberg Dollar Index. Meanwhile, Bank Indonesia's benchmark rupiah rate (Jakarta Interbank Spot Dollar Rate, abbreviated JISDOR) depreciated 0.58 percent to IDR 11,507 against the US dollar on Wednesday (21/05).
