Shares are mostly higher in Asia after a lackluster day on Wall Street, where major indexes spent the day drifting up and down near their record highs. Benchmarks rose in Hong Kong, Tokyo and Sydney but fell in Shanghai. On Wednesday, the S&P 500 edged 0.2% higher thanks in large part to gains from several Big Tech companies including Apple and Amazon, even though most stocks in the index fell. Treasury yields stalled following a rapid rise over the past few weeks. The benchmark 10-year yield dipped as concerns calmed that the Federal Reserve may curtail its purchases of Treasurys.
