Week in Review: Stocks See Worst Week Since Election as Trump Dealt Setback With Health-Care Bill

`` The passage of the bill was seen by Wall Street as a test as to whether Trump can enact all he has promised, particularly tax cuts and regulatory reform... The S&P 500 tumbled 1.44% over the past five days, its worst weekly loss since the week ended November 4. The Dow Jones Industrial Average fell 1.52%, and the Nasdaq slid 1.47%. Stocks had rallied to new heights over the past few months on high hopes a Trump administration would pass business-friendly regulatory reform and tax cuts.''
