Windward Bio listed on Nasdaq on November 13, 2026 at $17.00 and closed its first day at $28.50, up 68%, with a market cap of about $1.69 billion. Such a large first-day premium typically signals strong demand that can support the price in the following days as index and fund interest builds. The stock is clinical-stage with no revenue, so the premium could also fade as early investors take profits.
