Cerebras stock slides as UBS cuts price target and short‑seller report raises chip durability concerns

Cerebras Systems saw its shares tumble after UBS lowered its 12‑month price target to $250 from $330 and a short‑seller report alleged its wafers degrade after 1.5‑2.5 years. The decline comes amid a wave of insider lockup sales and precedes the company’s Q3 earnings scheduled for November 12.

UBS’s target reduction signals reduced near‑term conviction, which may pressure the stock further. The pending release of lockup shares adds supply risk ahead of the earnings report.
