(Reuters) -Activision Blizzard Inc shares fell 10% on Tuesday after Blizzard co-lead Jen Oneal decided to step down just after three months in the role and the company forecast underwhelming quarterly adjusted sales.

Oneal, who was appointed alongside Mike Ybarra, said she is leaving at the end of the year to focus more on diversity in the gaming industry.
