In a tumultuous week for the stock market, Wall Street experienced significant fluctuations in response to the conclusion of the US government shutdown. The Dow fell sharply, dropping over 800 points at one point, as traders adjusted their expectations regarding Federal Reserve rate cuts amid lingering economic uncertainty. Despite this, some sectors, particularly technology, saw a rebound with notable performances from companies like Palantir and Nvidia. Overall, while many stocks initially struggled, optimism surrounding the end of the shutdown sparked a brief rally, leading to mixed reactions across global markets, with European shares hitting record highs. Investors remain cautious as they await critical economic data that could influence future market movements.
