(Bloomberg) -- Asian stocks opened mixed Wednesday after U.S. peers retreated on concerns about excessive investor optimism. Treasuries held gains.
Shares rose in Japan and Australia but fluctuated in South Korea. S&P 500 futures edged up after technology shares led losses in the benchmark on Tuesday. The Nasdaq 100 was dragged down by Apple Inc. and Tesla Inc., which tumbled more than 4%.
Earlier, benchmark Treasury yields dipped amid comments from Federal Reserve Governor Lael Brainard that bond-market volatility may further delay a pullback in the central bank's massive asset purchases. U.S. inflation-adjusted yields retreated.
Investors are focusing closely on valuations amid concerns about excessive optimism in markets. China's top banking regulator warned Tuesday about the need to reduce leverage as well as the risk of bubbles in global markets. Bullishness among Wall Street strategists is approaching levels that have presaged potential trouble for stocks, according to a Bank of America gauge.
"We believe we're still very much in a bull market, but certain pullbacks like the one we've seen since the beginning of this year are very natural and sometimes needed," Katerina Simonetti, Morgan Stanley Private Wealth Management senior vice president, told Bloomberg TV. "If interest rates start moving higher and quicker than expected, then there's a chance there might be more significant pullback in the market."
Elsewhere, oil extended losses below $60 a barrel with the OPEC+ alliance said to be set to agree to a production increase later this week. Bitcoin fluctuated below $50,000.
