Stocks - Wall Street Cautious on Trump Impeachment; Tech Stocks Fall

Wall Street remained volatile on Wednesday, held back by fears of political instability after the House launched a formal impeachment inquiry into President Donald Trump. The U.S. House of Representatives decided to start the impeachment process on Tuesday, but uncertainty remains as to how much impact there will be, with the Republican-controlled Senate having to give its approval. The impeachment moves came after Trump withheld military aid from Ukraine while urging its president to investigate corruption allegations involving the son of former Vice President Joe Biden. "Of course, the headline news regarding impeachment investigation will be focused on, but I don't think that it's going to have a real negative effect just yet," said Peter Cardillo, chief market economist at Spartan Capital Securities in New York.
