Wall Street on track to snap four-day rally; latest trade threat weighsU.S. stocks looked set on Wednesday to snap a four-day winning streak after Washington's threat to impose tariffs on an additional $200 billion worth of Chinese goods fanned trade war fears, while a sharp drop in oil prices hit energy. China responded to U.S. President Donald Trump's threats by accusing the United States of bullying and warned that it would hit back. Industrial names including Boeing, 3M and Caterpillar, which have been among the hardest hit throughout the recent trade dispute, were among the Dow's biggest drags on Wednesday.
