Walter Strapps

Walter Strapps is a declared insider of Sona Nanotech Inc., with filings sourced from SEDI. Over a trading history stretching from 4 January 2022 to 13 October 2026, the count stands at 3 filings.

Not one of the filings records a straightforward purchase or sale on the market. 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.

On 15 October 2026 came the latest disclosure, an option exercise in Sona Nanotech Inc. The median gap between a trade and its publication by SEDI is 4 days. That lag is the time during which only the insider knows about the trade. Every figure here comes from the filings published by SEDI and describes the past, not future prices; it is not investment advice.
