Wall Street and European futures have slipped as concerns over renewed tariff threats from former President Trump weigh heavily on investor sentiment. The Dow, S&P 500, and Nasdaq futures show signs of pullback amid escalating trade tensions, particularly with looming tariffs on goods from Japan and South Korea. While some analysts warn of potential market shocks, others believe that markets may be underestimating the impact of these developments. The upcoming earnings season, combined with inflation worries, adds to the uncertainty. With escalating rhetoric surrounding tariffs, markets have experienced notable volatility but appear to be resilient, with some investors clinging to hopes of continued high performance despite the turmoil.
