Huang, who has been Morningstar’s chief operatin officer since 2000, said he wants “try other challenges in my business life not related to this industry, and the team is now in place that can make my departure seamless to the organization.”

Huang has worked at Morningstar since 1990, when he was hired as a software developer. From 1996 to 1998, he served as chief technology officer. From 1998 to 2000, he served as senior vice president of business development and head of international operations.
