Asian shares were mixed on Tuesday, with earlier losses pared after a huge sell-off on Wall Street, while traders were spooked by a double bombing that hit the Boston Marathon. The weak China outlook hit commodity prices, with gold sinking to its lowest level since 2011 in New York after suffering its sharpest fall in 30 years, while on oil markets the Brent contract sat below US$100 a barrel. Tokyo fell 0.41 per cent, or 54.22 points, to 13,221.44, and Sydney eased 0.34 per cent, or 17.1 points, to 4,950.8. Seoul ended flat, edging up 1.76 points to 1,922.21 while Hong Kong was 0.46 per cent lower, giving up 100.64 points to 21,672.03. However, Shanghai rose 0.59 per cent, or 12.91 points, to 2,194.85 on bargain-buying following three days of losses. The morning saw huge losses across the region but most bourses clawed them back as earlier risk aversion dissipated. Global markets suffered a downturn on Monday after China released data showing growth in the world's number-two economy had slowed in the first quarter of the year, which was followed by weak US manufacturing figures. Asian markets ended Monday in the red and Wall Street's main indexes were already down when two explosions hit the Boston Marathon, one of the biggest sporting events in the US, killing at least three and injuring more than 100. As cities across the United States went on high alert President Barack Obama said it was not yet clear who was behind the explosions. While he did not say the blasts were a terror attack, a White House official said "any event with multiple explosive devices - as this appears to be - is clearly an act of terror". On Wall Street, the Dow and S&P 500, which last week hit record highs, both slid. The Dow dived 1.79 per cent and S&P 500 plunged 2.30 per cent, while the tech-rich Nasdaq was 1.94 per cent lower. US data showing a larger-than-expected slowdown in New York state manufacturing in April and a drop in confidence of homebuilders added to concerns. The dollar rebounded to 97.76 yen in early European trade, from 96.56 yen in New York on Monday, but it is still well down from the 99.95 yen seen on Friday. The euro was at 127.65 yen and US$1.3055, against 125.98 yen and US$1.3048. The China results hit commodities, with gold at lows not seen since February 2011, while oil prices also sank, with Brent falling below US$100 a barrel for the first time since mid-July. Gold plunged more than 13 per cent between Friday's open and Monday's close in New York on worries over China's growth. At one point in intra-day US trade, it fell as low as US$1,338.00 an ounce - a fall of more than 10 per cent representing its worst dive since 28 February 1983. However, at 1045 GMT on Tuesday, the precious metal had recovered slightly and was at US$1,391.10 an ounce. Dealers have also been spooked by reports last week that Cyprus was preparing to liquidate some of its 14 tonnes of gold reserves to fund its part of an IMF-EU bailout plan. But the broader view is that with inflation expectations still flat - as both US and Chinese data indicate - people who buy gold as a hedge against rising prices have been driven to dump bullion. On oil markets Brent North Sea crude for May delivery shed US$1.02 to US$99.61 as the weak China figures raised concerns about demand from the world's biggest energy consumer. New York's main contract, light sweet crude for May, dropped 71 cents to US$88.00. "You can't continue buying risky high-yield assets, which require growth ultimately, if the growth outlook is deteriorating," Greg Gibbs, senior foreign exchange strategist at the Royal Bank of Scotland in Singapore, told Dow Jones Newswires. In other markets, Taipei rose 0.48 per cent, or 37.52 points, to 7,801.05; Manila fell 0.75 per cent, or 51.44 points, to 6,786.33; Wellington fell 0.60 per cent, or 26.87 points, to 4,427.83; Jakarta jumped 1.04 percent, or 50.66 points, to 4,945.25, Kuala Lumpur added 0.16 per cent, or 2.76 points, to 1,700.53; and Mumbai rose 2.11 per cent, or 387.13 points, to 18,744.93. Bangkok was closed for a public holiday.
