On October 16, Cerebras Systems fell 5.25% in Regular Trading, trading at $135.0409 per share, with turnover of $231 million.

The main catalyst cited by market updates was continued pressure from bearish options flow, highlighted by an $8.5888 million net-premium same-direction double short put structure with $175 and $170 strikes, a positioning pattern centered on collecting premium while signaling expectations for range-bound trading and restrained risk appetite.

Recent derivatives activity had already turned cautious: earlier reports pointed to a $1.365 million deep-in-the-money long-dated $170 put block and a calendar call structure that brought in $195,700 in net premium, both suggesting expectations for medium-term pullback or limited upside. In the broader semiconductor group, weakness was also visible, with Micron Technology falling 3.58%, AMD falling 3.09%, Intel falling 2.85%, Broadcom falling 1.9%, while NVIDIA was up 0.04%.
