Viscofan Stock Plunges on US “Toxic Emissions” Allegations – Is a Rebound Coming?
Viscofan’s stock declined sharply in mid-October 2025, reflecting a sudden drop in investor confidence. On Oct 14, shares slumped ~13% intraday – the steepest fall since 2018 – after a US-based news report accused Viscofan’s largest North American plant of uncontrolled “toxic” emissions cincodias.elpais.com cnmv.es. By Oct 15, VIS.MC traded around €50.7 marketscreener.com. This represented about a 5-day loss of –12.7% marketscreener.com and brought the 2025 decline near –17%. The sector and Spanish indices showed little special weakness, suggesting the drop was driven by company-specific fear and heavy selling pressure. Intraday charts show high volatility in mid-October, and social media/forums report traders scrambling to cover positions. Despite the selloff, trading volume was moderate – implying most selling may have been algorithmic or speculative. Sentiment appears cautious: some retail investors note the share buyback and insider buying as support, but many await clarity on the Danville issue.
