Asian equities tumble on US earnings, weak commodities

Asian stock markets outside Shanghai stumbled on Wednesday, hurt by lackluster earnings on Wall Street and the fall in commodity prices.

Spot gold plunged to $1,092 an ounce by mid-day, struggling to move away from five-year lows. Energy prices also stayed downbeat, with West Texas Intermediate (WTI) crude falling 1.5 percent to $50.12 a barrel, and Brent crude for September down nearly 1 percent to $56.54 a barrel.

Overnight, lackluster earnings from a few blue chips pressured the down 1 percent. The S&P 500 and the shed 0.4 and 0.2 percent, respectively.

Among the tech titans releasing corporate results, Apple unveiled better-than-expected earnings for the third quarter, but shares dropped sharply in after-hours trading as the iPhone maker's forecast for the next quarter disappointed.

Mainland markets mixed

Bucking the regional downtrend, China's benchmark Shanghai Composite index recouped losses to finish 0.2 percent higher.

"If investors in China are confident that the Chinese government will hold the line, then the margin debt will unwind slowly and end up stabilizing around current levels. While there are still concerns about ChiNext and small-cap stocks which remain overvalued, the price-to-earnings multiples isn't excessive by global standards if you look at the large-cap indexes," Shane Oliver, head of investment strategy and chief economist at AMP Capital, told CNBC Asia's "Squawk Box."

"From a valuation point of view, I don't see a major problem with China's equity markets and with the authorities set to continue easy monetary conditions, I think that the rising trend established in the previous sessions will probably continue," he added.

Elsewhere in the country, the blue-chip CSI300 index slipped 0.2 percent, while the smaller Shenzhen Composite closed up 1 percent. In Hong Kong, the Hang Seng Index fell 1.1 percent.

Specific stocks in focus include China Construction Bank which settled 0.6 percent lower in Shanghai, following news that the Federal Reserve told the bank to do more to fight money laundering on Tuesday.
