Cerebras Systems' stock plummeted 5.40% in pre-market trading on Tuesday.
The decline followed the initiation of coverage on the company by Freedom Capital Markets with a Hold rating. Analyst initiations with neutral ratings can sometimes disappoint investors who may have anticipated a more positive outlook, leading to selling pressure.
Additionally, the stock faced downward pressure from newly disclosed insider selling by Chief Operating Officer Dhiraj Mallick, combined with profit-taking activity after the stock had rallied approximately 18% over the prior two trading sessions.
