In pre-market trading on Tuesday, major U.S. stock indexes, including the S&P 500, Nasdaq, and Dow Jones Industrial Average, showed gains of between 1% and 2%, reflecting cautious optimism despite recent volatility. The ongoing trade conflict between the U.S. and China, exacerbated by President Trump's announcement of potential additional tariffs, continues to create uncertainty in global markets. Despite these tensions, global stocks, including the Nikkei 225 index in Tokyo, managed to recover some losses, indicating a modest rebound and signs of stabilization in financial markets.
