COMEX copper stays pressured amid firm dollar overseas, making dollar-priced metals costlier for holders of other currencies. Markets are concerned about President-elect Donald Trump's proposed import tariffs, which could harm global economic growth. His pledges might also disrupt the global metal demand-supply balance and potentially lead to price fluctuations. Meanwhile, in overnight trades, despite the choppy trading, the Nasdaq and the S&P 500 once again reached new record closing highs. The major averages eventually ended the day mixed. While the Dow dipped 76.47 points or 0.2 percent to 44,705.53, the Nasdaq rose 76.96 points or 0.4 percent to 19,480.91 and the S&P 500 crept up 2.73 points or 0.1 percent to 6,049.88. Currently, the red metal is quoting at $4.17 per pound, down 0.54% on the day.
