The S&P 500 index recorded its best performance in a president's first week.

This week, the S&P 500 Index recorded its best first-week performance under any president since Reagan. The market-friendly Trump that Wall Street hoped for is delivering on promises, pushing for growth and tax-cutting policies while postponing plans that could immediately disrupt the global trade order. Despite protectionist threats during the campaign, Trump did not impose tariffs on major trading partners this week and sent a calming message to China last night, indicating a preference for not imposing tariffs on the world’s second-largest economy. This sparked a widespread market rebound.
