    Dec 3 (Reuters) - Wall Street fell more than 1% and the
benchmark S&P 500 hit a near one-month low on Tuesday, as
comments from President Donald Trump and Commerce Secretary
Wilbur Ross stoked fears of a significant delay in resolving a
trade dispute with China.
    Speaking to reporters in London where Trump was attending a
meeting of NATO leaders, he raised the possibility of the trade
deal being delayed until after the U.S. presidential elections
in November 2020.  urn:newsml:reuters.com:*:nL8N28D2KI
    Ross told CNBC that planned tariffs on Chinese imports will
be imposed on Dec. 15 unless there is some real reason to
postpone, such as substantive progress in talks.  urn:newsml:reuters.com:*:nW1N26F017
    Nine of the 11 major S&P 500 sectors were trading lower,
with tech heavyweights Apple Inc  AAPL.O  and Microsoft Corp
 MSFT.O  weighing the most.
    The trade-sensitive Philadelphia Semiconductor index  .SOX 
dropped 2.4% to hit an over one-month low.
    Tuesday's declines added to the pullback in the previous
session, from record highs hit last week, on hopes that the two
sides will hammer out a "phase one" deal soon, and signaled a
rough start to the month.
    "This is sort of a last-minute negotiation tactic," said
Robert Pavlik, chief investment strategist and senior portfolio
manager at SlateStone Wealth LLC in New York.
    "If the Dec. 15 tariffs go into effect, then I think people
start thinking that this could have additional ramifications on
a 'phase-one' ever getting done."
    The S&P 500 is still up about 23% this year, helped by
interest rate cuts from the Federal Reserve, even as conflicting
headlines on trade have caused some volatility.
    At 11:31 a.m. ET, the Dow Jones Industrial Average  .DJI 
was down 438.25 points, or 1.58%, at 27,344.79, the S&P 500
 .SPX  was down 36.21 points, or 1.16%, at 3,077.66 and the
Nasdaq Composite  .IXIC  was down 106.03 points, or 1.24%, at
8,461.96.
    Shares of Audentes Therapeutics Inc  BOLD.O  more than
doubled in value after Japan's Astellas Pharma Inc  4503.T  said
it would buy the U.S. drugmaker for about $3 billion in cash.

    AK Steel Holding Corp  AKS.N  rose 5% after miner Cleveland
Cliffs Inc  CLF.N  agreed to buy the steel maker for about $1.1
billion in an all-stock deal. Shares of Cleveland-Cliffs slumped
11.4%.  urn:newsml:reuters.com:*:nBw4bD47va
    Declining issues outnumbered advancers for a 2.45-to-1 ratio
on the NYSE and a 2.34-to-1 ratio on the Nasdaq.
    The S&P index recorded one new 52-week high and four new
lows, while the Nasdaq recorded 17 new highs and 53 new lows.
