An analyst downgraded Nio Inc. (NIO), citing concerns that sustained weakness in China's consumer market is weighing on the electric vehicle sector. The report said deteriorating retail sales, particularly vehicle sales, could prevent Nio from maintaining its growth trajectory despite impressive year-to-date sales growth.

Investor sentiment toward EV stocks is already subdued. Nio has shown positive signs, including expectations for continued growth and potential profitability, but macroeconomic headwinds in its key market remain a major obstacle. The stock has underperformed the broader EV index year-to-date.
