Asian shares are mixed after Wall St sets a record, and the US dollar's value slides further

Asian shares are mixed after the S&P 500 ticked to a record and the U.S. dollar's value slid further. The dollar has lost about 3.8% since last week and was trading near 153 yen early Wednesday. South Korea's benchmark hit a record, lifted by gains for technology shares. The price of gold surged past $5,200 and silver's price jumped more than 8%. The Federal Reserve will announce its next move on interest rates later Wednesday. It's expected to keep its main interest rate steady. On Tuesday, the S&P 500 rose 0.4% to a record even though more stocks fell within the index than rose. The Dow Jones Industrial Average dropped 0.8%, and the Nasdaq composite rose 0.9%.
