Cigna is trading 4.17% down at $263.77 on September 30, 2026; no verified company-specific cause for the selloff has been identified. - Investor Day announced a $3 billion multi-year modernization and productivity initiative and reaffirmed 2026 guidance. - Cigna set a 10%–14% adjusted EPS growth target through 2030; the announcement’s connection to the decline remains unclear. - Major indexes were higher, so broad-market weakness does not explain the drop.
