NIO Inc's shares have been volatile this week, with a 2.6% gain on Monday followed by a drop on Tuesday. The fluctuation follows the company's announcement of increased production of its ES6 vehicle after a temporary halt in August for manufacturing process upgrades. NIO's monthly delivery numbers have shown a steady increase in Q2, with 20,462 vehicles delivered last month. However, forecasts for China's economic expansion have been revised lower due to rate uncertainty, pressuring several Chinese companies. NIO is expected to report a Q2 loss of 36 cents per share and revenue of $1.35 billion on August 29.
