March 27 (Reuters) - Wall Street's main indexes treaded water on Wednesday as global growth fears lingered and the U.S. yield curve extended an inversion, prompting investors to stay on the sidelines.
Apple Inc was a bright spot, up 0.87 percent after three straight days of losses.
The benchmark 10-year Treasury yields slid on Wednesday, but came off 15-month lows reached overnight as investors remained focused on central bank dovishness globally. The inversion, if it prolongs, could indicate that a recession is likely in one to two years.
U.S. stocks have been hit by worries of slowing global economic growth since last week following dour factory data from the United States, Europe and Japan, as well as weak consumer confidence numbers for March this week.
Adding to the concerns, Chinese data on Wednesday showed industrial profits shrank the most since late-2011 in the first two months of the year.
"There has been recent jitters and choppiness in the market created by a buffet of concerns, it's not just one thing, so this morning investors are taking a pause," said Andre Bakhos, managing director at New Vines Capital LLC in Bernardsville, New Jersey.
"The yield curve being inverted is another data-point that investors are looking at, that's why our relationship with China and global growth become a concern."
The European Central Bank said on Wednesday it could further delay a planned increase in interest rates as it faces rising threats to growth, a week after the Federal Reserve abandoned any rate hikes this year.
At 9:58 a.m. ET, the Dow Jones Industrial Average was down 16.84 points, or 0.07 percent, at 25,640.89. The S&P 500 was down 3.91 points, or 0.14 percent, at 2,814.55 and the Nasdaq Composite was down 14.89 points, or 0.19 percent, at 7,676.63.
Data showed that U.S. trade deficit dropped more than expected in January, likely as Chinese purchases of soybeans spurred a rebound in exports after three straight monthly declines.
Markets also awaited new developments on trade talks between the United States and China with a new round of high-level negotiations scheduled to start on Thursday.
Industrials gained 0.26 percent, the most among the 11 major S&P sectors with airline stocks leading gains. The S&P 500 airlines index rose 2.7 percent.
Centene Corp's shares slipped 7.74 percent after the health insurer said it would buy smaller rival WellCare Health Plans Inc for $15.27 billion. Shares of WellCare jumped 10.23 percent.
Lennar Corp rose 1.85 percent as the homebuilder said it expected improving housing market even after missing Wall Street estimates for the first quarter.
Declining issues outnumbered advancers for a 1.11-to-1 ratio on the NYSE and for a 1.43-to-1 ratio on the Nasdaq.
The S&P index recorded 27 new 52-week highs and one new low, while the Nasdaq recorded 20 new highs and 14 new lows. (Reporting by Shreyashi Sanyal and Amy Caren Daniel in Bengaluru; Editing by Sriraj Kalluvila)
