March 23 (Reuters) - Nike and energy companies led modest gains in U.S. stocks on Friday, amid lingering fears of a trade war, although a Micron-led slump in semiconductor companies kept gains in check.
The Dow Jones Industrial Average was modestly higher, helped by Nike and as industrial stocks gained after a bruising day on Thursday when the United States moved to impose tariffs on up to $60 billion of Chinese imports, sparking fears of a trade war.
China on Friday retaliated by disclosing own plans for tariffs on up to $3 billion of U.S. imports, but also urged the United States to “pull back from the brink.”
“Nothing’s happened yet, except for the tariffs in the U.S. Investors don’t want to sell and buy back at a higher price and if the diplomacy wins and trade war is not as severe as everyone’s thinking,” said Adam Sarhan, chief executive of 50 Park Investments in New York.
“So right now the market’s in a wait-and-see period, they are waiting to see what the next catalyst will be - bullish or bearish.”
