An index of Asian shares edged higher on Tuesday, bolstered by another record day on Wall Street, while a resurgent yen helped knock the U.S. dollar index off an 11-year high, Reuters reported. The Australian dollar jumped after the Reserve Bank of Australia held policy steady, confounding investors who had bet it would deliver a back-to-back interest rate cut instead of holding off for a few months to gauge how the economy digested last month's cut. But Japan's Nikkei stock average erased early gains and ended 0.1 percent lower, after the yen rebounded from a three-week low against the greenback touched earlier in the session. China stocks tumbled as investor excitement over a weekend interest rate cut waned, with a flood of new initial public offerings (IPO) fanning concerns about tighter liquidity. The Shanghai Composite Index fell more than 2 percent. On Wall Street, the Dow Jones industrial average and the S&P 500 both posted fresh record closing highs, while the Nasdaq Composite broke 5,000 for the first time in 15 years. The dollar index climbed as far as 95.516 earlier in the session, its highest since September 2003, but was last down about 0.2 percent on the day at 95.317. The euro gained about 0.1 percent on the day to $1.1195 .
