This had severely dented the confidence of investors. However, Treasury Secretary Steve Mnuchin on Sunday said, “We are putting the trade war on hold.” The two countries on Saturday started negations to avoid a possible trade war. Further, negotiators said that they would continue discussing measures so that China starts importing more energy and agricultural products from the United States to narrow the $335 billion annual trade deficit with China.Mnuchin’s statement reinstated the confidence of investors, which saw stocks rallying. Industrials were the biggest gainers as they would stand to benefit the most if a trade war is averted. Shares of Boeing, Caterpillar and United Technologies jumped 3.6%, 2.6% and 2.3%, respectively.
