Hesai Group is trading at $12.78, down 4.34%, amid renewed pressure on technology and semiconductor stocks as investors question the cost and debt financing of AI infrastructure. - Reuters reported Friday that worries about cracks in the AI trade pressured semiconductor shares; concern about CoreWeave’s debt contributed to investors cutting exposure to AI-adjacent companies. - No announcement explaining the October 16 decline surfaced. Hesai’s Kosmo launch was reported earlier in the week, not as a new catalyst today.
