Lewis Chew

Lewis Chew has filed trades across 4 companies (mainly through SEC (Form 4)), most often in Arista Networks, Inc., Cadence Design Systems Inc and Dolby Laboratories, Inc. We count 31 filings; the first trade dates from 20 May 2021 and the latest from 20 August 2026.

No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.

The latest filing, published on 24 August 2026, reports an option exercise in Arista Networks, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
