Wall Street is retreating a bit more as a five-week rally loses momentum. The S&P 500 was 0.4% lower Wednesday. It’s on pace for a third straight pullback after rallying last week to its highest level in more than a year. The Dow Jones Industrial Average edged down by 9 points, or less than 0.1%. The Nasdaq composite was lagging the market with a 1.2% loss as Big Tech stocks weakened after Federal Reserve Chair Jerome Powell said again that more hikes to interest rates may be on the way to get inflation under control. Treasury yields rose.
