For years, Seres Group Co. leaned on Chinese technology champion Huawei Technologies Co. to transform an assembler of cheap minivans into the maker of the country’s top-selling luxury vehicle. Now, it’s ready to come into its own.

The company, which recently completed one of the world’s biggest listings this year, had its Hong Kong trading debut on Wednesday. The stock ended up flat amid a down day for stocks globally, giving the company a market value of about $35 billion.
