The US stock market is showing positive momentum as the S&P 500 has not only erased its losses for the year but is also on track for a potential fifth consecutive gain. Encouraging signs from trade developments and softer inflation data have contributed to this upward trend. Major indexes, including the Dow and Nasdaq, have also ticked higher, reflecting optimism among investors. Despite some mixed signals in midday trading, the overall sentiment remains bullish as Wall Street builds on a strong weekly performance.
