By Kevin Plumberg HONG KONG (Reuters) - Asian stocks rose to a 14-month high on Tuesday after strong sales numbers from Apple Inc suggested U.S. consumers are spending more and as the weak U.S. dollar kept pushing commodity prices higher. Oil topped $80 a barrel and gold neared a record high, with the dollar locked in a steep downtrend as investors searched for higher returns elsewhere. Portfolio flows into emerging market assets have been torrential, leading Brazil to slap a 2 percent tax on foreign investment in domestic stocks and bonds to try to cool its real currency, which has surged 36 percent this year. Japan's Nikkei share average rose 1.1 percent, supported largely by a mixture of stocks in the technology sector. "These (U.S.) results are inevitably providing a bit of a boost, particularly for parts suppliers and chip makers, while a whole range of China-linked shares are also doing well," said Koichi Ogawa, chief portfolio manager at Daiwa SB Investments in Tokyo. Shares of Komatsu Ltd (6301.T), the world's second-biggest maker of construction equipment, rose 2 percent after a report the company had made 10 billion yen in operating profit for the July-September quarter on demand from China and other developing markets. The benchmark MSCI index of Asia-Pacific shares outside Japan .MIAPJ0000PUS rose more than 1 percent. U.S. stock futures rose 0.4 percent after profits at Apple Inc (AAPL.O), released after the closing bell, exceeded market forecasts on record quarterly sales of iPhones and Macs. Shares of Apple jumped 7.5 percent in after-hours trading to a record high. During the regular session, U.S. stocks gained about 1 percent to fresh 12-month highs as investors cheered a wave of solid quarterly earnings. .N Investors have been anxiously awaiting earnings season for signs that consumer demand is improving, which would reinforce the chances of a sustainable global economic recovery and give new legs to a seven-month equity rally which has been showing signs of flagging. Company earnings in the last quarter were largely bolstered by cost cutting as opposed to a true pick-up in demand for their products. DOLLAR WEAKNESS The dollar fell to its lowest in 14 months against a basket of currencies on persisting views that policy makers in the United States will stick to a low interest rate policy for some time while they await signs that an economic recovery is on solid footing. The dollar index, a gauge of its performance against six major currencies, fell as far as 75.150 .DXY, its lowest since August last year. The euro was up 0.1 percent at $1.4986 but was meeting selling pressure by dealers protecting positions at the round figure of $1.50.
