The stock markets experienced significant gains today, with the Dow closing up nearly 400 points and both the Nasdaq and S&P 500 soaring as optimism surrounding an impending resolution to the US government shutdown grew. A breakthrough in the Senate aimed at halting the shutdown has sparked a market rally, lifting not only US indexes but also boosting global markets such as the FTSE 100, which reached a record high. Investors are reacting positively to the news, with increased buying in tech stocks leading the charge. Even amidst this optimism, experts caution that the end of the shutdown may only serve as a temporary relief for the market, rather than a long-term solution to ongoing economic concerns.
