John Kosiba: trading record in brief
All filings by John Kosiba on record concern American Superconductor Corp /DE/. In total, 4 filings cover trades dated from 2 June 2026 to 11 June 2026.
Not one of the filings records a straightforward purchase or sale on the market. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.
The newest entry dates from 11 June 2026: a transaction of €219k, in American Superconductor Corp /DE/. The median gap between trade and publication is zero days: most filings appear on the same day. US insiders must file a Form 4 within two business days of a trade. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
