Gary B Smith, President and CEO, sold 2,952 shares of CIENA CORP (CIEN) at $457.02 on 2026-06-15, reducing holdings from 269,557 to 266,605 shares. The sale occurred under a pre-arranged 10b5-1 trading plan, meaning it was scheduled rather than discretionary. The stock currently trades at $436.72, down 31.5% from its 52-week high and off 16.7% in the prior 30 days. Across his entire insider trading history (cross-ticker), Smith's prior 19 sells yielded an average 90-day return of +64.6%, but at CIEN specifically, his most recent measurable sale (2026-05-15) showed a -20.6% 30-day return; the stock's recent weakness may reflect broader sector or company headwinds rather than a scheduled plan execution.
