Most U.S. stocks rose following another topsy-turvy day on Wall Street.

The S&P 500 added 0.4% Wednesday, but only after jumping toward one of its biggest gains since the summer, erasing it all and then climbing back. The Nasdaq composite climbed 0.7%, and the Dow Jones Industrial Average lagged the market after edging down by less than 0.1%.

Trading has been erratic since the end of last week, when President Donald Trump shattered Wall Street’s calm by threatening higher tariffs on China.

Technology and bank stocks helped lead the way Wednesday.
