On July 6, Cerebras Systems fell 5.3% in regular trading, trading at $194.64/share, with turnover of $173 million. The decline comes as multiple U.S. law firms continue their securities fraud investigations into the company, alleging potential federal securities law violations during its IPO process.

The investigations center on disclosures made in Cerebras's first quarterly earnings report on June 23, which revealed that the company leased back its own systems from existing customers to expand compute capacity, a move that temporarily compressed core cloud service margins by an estimated 10 to 15 percentage points. Additionally, COO Dhiraj Mallick's net sale of approximately 36,131 shares on June 25 continues to weigh on investor sentiment regarding insider confidence.

The stock's weakness stands in contrast to the broader semiconductor sector, where Advanced Micro Devices gained 8.23%, Broadcom rose 5.6%, Intel added 3.98%, Micron Technology climbed 1.97%, and NVIDIA advanced 0.72%.
