Stephen Trundle: trading record in brief
Stephen Trundle, listed as chief executive, appears in our data through filings on Alarm.com Holdings, Inc. shares, published by SEC (Form 4). Over a trading history stretching from 2 June 2017 to 2 September 2026, the count stands at 116 filings.
Market trades split into 1 purchase (€148k) and 70 sales (€51.2M). Netting one side against the other leaves €51.1M of net selling. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Other entries cover 9 share grants and 27 option exercises. 2026 to date brings no purchases and 2 sales.
The record was last updated on 4 September 2026 with a transaction in Alarm.com Holdings, Inc. The latest purchase dates back some time: it was published 335 days ago, on 20 November 2025. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. The legal deadline for a Form 4 is two business days after the transaction. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
