 Shares of Nio Inc. spiked up 12.8 in afternoon trading Monday, after the China-based electric vehicle maker and Tesla Inc. rival reported upbeat July deliveries data. Nio said it delivered 2,533 vehicles in July, up more than fourfold up 322.1 from a year ago, including 2,610 of its ES6 5-seater SUV and 923 6-and-7 seater ES8 SUVs. In July, we are pleased to have achieved the second-highest monthly delivery results despite the impact on productions due to a 5-day suspension of manufacturing to prepare for EC6 productions and other flood-related supply chain challenges, said Chief Executive William Bin Li. That helped boost other EV makers, with Teslas stock surging 3.8 and Nikola Corp. shares run up 15.4. Nikola is scheduled to report second-quarter results after Tuesdays closing bell. Separately, Electric truck maker Lordstown Motors Co. will become public, after agreeing to be acquired by blank-check company DiamondPeak Holdings Corp. , which said its stock soar 16.2 on the news. The rally in EV maker shares comes as the SP 500 gained 0.9.
