What Was Ciena Telling You Before Its Stock Ran?

Ciena (CIEN) stock returned 101.5% from October 16, 2025 to October 19, 2026, against 17.4% for the S&P 500. The run turned out to be about cloud providers and data centers ordering more of Ciena's optical networking gear than the company could ship. The rise began earlier, however. Shares had already risen 184% in the six months before that window opened. So what was Ciena telling investors before April 2025, when its shares still traded near $60.
