Shares of Caterpillar Inc. surged 3.0% in morning trade Monday, enough to pace the 29 of 30 Dow Jones Industrial Average components that are gaining ground, as optimism over a trade deal with China helped fuel a broad market rally. Caterpillar’s stock has now recovered everything it has lost since investors started fearing a trade war on Feb. 16, when the U.S. threatened tariffs on steel and aluminum imports. Tariffs on steel would raise raw material costs for Caterpillar, while retaliatory measures could also hurt given China is Caterpillar’s third-largest market, behind the U.S. and Canada, according to FactSet. Caterpillar’s stock had dropped 2.3% on Feb. 16, and had lost as much as 11% after the initial tariffs were announced, before bouncing. The stock has now run up 56% over the past 12 months, while the Dow has rallied 20%.
