US Futures are lower on the first trading day of Q2. After nine consecutive quarterly gains for S&P 500 stocks, the S&P 500 recorded its first quarterly loss since the third quarter of 2015. To start the quarter, this week will see heavier than usual economic data. Later this morning the market will get a look at the March PMI manufacturing index, ISM manufacturing index and February construction spending. To end the week we will get readings on March employment and wage situation. Most European markets are closed today for Easter Monday. Asian shares closed mostly lower after China announced a new round of tariffs on US goods.
