Tanya Lewis: trading record in brief
Tanya Lewis has filed trades across 2 companies (mainly through SEDI), most often in Sernova Biotherapeutics Inc. and DiaMedica Therapeutics Inc. The record holds 3 filings, for trades running from 22 May 2026 to 1 June 2026.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.
The latest filing, published on 4 June 2026, reports an option exercise in DiaMedica Therapeutics Inc. Between a trade and the moment it shows up on SEDI, the median delay is 5 days. The shorter that gap, the sooner other investors can see what insiders have done. Source: insider filings from SEDI. Past trades are no guide to future returns.
