Several telecom equipment vendors and component suppliers are selling off in sympathy with Calix (CALX -22.7%) and Cyan (CYNI -31.8%), each of which is crashing due to the poor Q4 guidance (I, II) provided with its Q3 results. Both companies are heavily dependent on U.S. telco spending.
Calix blamed its guidance on soft demand from tier-2 and tier-3 carriers, while Cyan blamed "cautious order patterns" caused by macro issues. On its CC (transcript), the company noted orders from top customer Windstream will be "substantially down compared to prior quarters."
Notable decliners include Finisar (FNSR -7.3%), JDS Uniphase (JDSU -3%), Ruckus (RKUS -6.6%), Applied Micro (AMCC -3.8%), Procera (PKT -4.1%), Allot (ALLT -3.8%), Ciena (CIEN -2.7%), and Alliance Fiber (AFOP -7.7%). JDS and Ruckus report after the bell; Allot and Procera rallied yesterday in response to the former's Q3 report.
Several industry names sold off last Thursday due to Infinera's soft Q4 guidance. Infinera said at the time it doesn't "expect significant budget flush or year-end money" from carriers.
