Markets pulled it together last week, with oversold financial and consumer stocks finding support and delivering gains for the holiday-shortened week. However, the market started this week with another sharp pullback Monday, bringing the Dow and S&P 500 back to their February lows. And markets look set to open lower today after China announced a slew of retaliatory 25% tariffs on U.S. exports. A rebound later this week is likely, but not certain.
