David M. Rothenstein: trading record in brief
David M. Rothenstein is a declared insider of Ciena Corp (senior executive), with filings sourced from SEC (Form 4). Over a trading history stretching from 4 February 2016 to 15 October 2026, the count stands at 107 filings.
The open-market record consists of 64 sales worth €15.8M, with no purchase. The amount is not disclosed for 2 filings. The rest of the record consists of 43 share grants. 2026 to date brings no purchases and 9 sales.
The record was last updated on 19 October 2026 with an open-market sale (€776k) in Ciena Corp. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
