 I'm Seth Zuttel, and this is Markets in a Minute. Stocks wobbled on Wall Street ahead of Federal Reserve Chair Jerome Powell's testimony before the Senate Banking Committee. The S&P 500 was up 0.2% in morning trading Tuesday. The Nasdaq Composite was up 0.4%. The Dow Jones Industrial Average slipped 138 points. That's about 0.4%. Consumer goods company Helen of Troy, which makes Osprey and Oxo products, sank 30% after posting first quarter results that fell far short of forecasts.
