Mining and construction equipment maker Caterpillar’s (NYSE: CAT US) shares dropped as much as 5.4% on Monday, the biggest intraday decline since Nov. 4, as prices of iron-ore and metals continued to fall, with China stepping up restrictions on industrial activity in some provinces. Broader investor concerns about the China real-estate crackdown, and growing doubts about the future of President Biden’s infrastructure bill also weighed on sentiments for mining and industrial sectors. CAT shares are 4,8% up for the year.
