Moderna (MRNA) Stock Hits 52-Week New High: Here Is Why
Moderna's stock (MRNA) rose 14.21% on October 9, 2026, reaching a 52-week high of $225.00. The increase was driven by its inclusion in the Nasdaq-100 Index and news of a U.S. Cancer Vaccine Initiative. The initiative, launching in December, focuses on personalized cancer vaccines, benefiting Moderna's mRNA cancer vaccine research. Moderna's market cap is $89.83 billion, but it remains unprofitable.
