Asian stocks extend selloff; Morgan Stanley downgrades MSCI China · CNBC

Asian stocks remained in the doldrums on Thursday, hit by a confluence of factors, which includes a weaker finish on Wall Street overnight, growth worries in Australia and jitters over tighter margin trading rules in China.

Overnight, U.S. markets were spooked by higher bond yields and as investors weighed the ADP Employment Report which showed 169,000 jobs created in April, missing expectations for a rise of 200,000.

While the ADP report focuses on the U.S. private sector, it is usually seen as a pre-cursor to the all-important nonfarm payrolls data released by the Bureau of Labor Statistics on Friday. A Reuters poll expects the U.S. to add 208,000 jobs in April, after posting its worst report since December 2013 in March with the creation of 126,000 jobs.

Meanwhile, comments from Federal Reserve chair Janet Yellen that the equities market is overvalued added to the market anxiety. As a result, the blue-chip Dow and the S&P 500 dropped 0.5 percent each, while the Nasdaq Composite shed 0.4 percent.

Mainland markets fall

China's Shanghai Composite index chalked up a third straight day of steep declines, diving 2.8 percent due to persisting worries over further government measures curbing speculation and the possibility that new stock listings may sap funds from existing equities. The Shanghai bourse had fallen nearly 6 percent over the last two sessions.

Morgan Stanley (NYSE: MS) downgraded the MSCI China index - which captures large and mid-cap Chinese companies listed in Hong Kong - to equal-weight, from overweight, marking the first downgrade in seven and a half years. "Dramatic recent outperformance has led to a deterioration in absolute and relative valuations and a technically overbought situation," analysts wrote in a report released early Thursday.

And Morgan Stanley is not alone. "Onshore A-share market performance over the last 6 months have been incredible... and I think they are now catching up to reality and more appropriate valuations. After all, the run up has been a bit too far and too fast," Bruno Del Ama, CEO of Global X Funds, told CNBC's " The Rundown ."

Among the most active stocks, China Shipbuilding and China State Construction Engineering fell by the daily limit of 10 percent, while Agricultural Bank of China erased 1.6 percent.

Hong Kong's Hang Seng index took cues from their mainland peers to settle 1.3 percent lower at its lowest level since April 20.

Nikkei drops 1.2%

Japan's Nikkei 225 (Nihon Kenzai Shinbun: .N225), which reopens for its first trading session this week after being shuttered for the Golden Week holiday since Monday, closed at a a one-month low.
