On October 15, Cerebras Systems fell 5.04% in Regular Trading, trading at $137.765 per share, with turnover of $354 million.

The move coincided with options data showing a calendar call spread that generated net premium of about $195,700, structured mainly as a bear call spread combined with longer-dated call selling, signaling expectations that the stock’s upside may be capped.

Recent positioning had already turned cautious: an earlier in-the-money put block worth about $1.365 million at the 170 strike in longer-dated contracts pointed to a medium-term pullback view. Although OpenAI previously reiterated Cerebras Systems is a close partner, that positive commentary has not reversed the stock’s recent downtrend, with bearish and call-writing signals in the options market continuing to weigh on risk appetite.
