U.S. stock futures opened lower at the start of the week, with S&P 500 futures trading below 5800 for the first time since November 5, 2024. This decline has erased nearly $2.5 trillion in market capitalization over the past four weeks, marking the end of the post-election rally. The S&P 500 is now down approximately 5% from its December peak and has returned to levels seen before the election. The Volatility Index (VIX) spiked by 11% amid investor concerns regarding rising yields and Federal Reserve rate jitters. Despite a challenging start, the market showed signs of recovery later in the day, with the Dow Jones Industrial Average gaining 350 points, while the S&P 500 managed to finish in the green, albeit with the Nasdaq closing down 0.4%. Analysts are closely monitoring key levels as inflation data is expected to be released this week.
