Gossamer Bio stock gains 12.04 percent in the latest quote

Gossamer Bio stock was quoted at USD 11.67 on September 22, 2026, with a 5-day gain of 3.46 percent and a year-to-date gain of 12.04 percent. The market data came from a real-time Cboe BZX estimate, so the quoted venue is separate from the Nasdaq primary listing.

Market data sets the tone

The September 22, 2026 snapshot places the shares at USD 11.67. The 12.04 percent year-to-date change provides the clearest quantified comparison in the available market record, while the 3.46 percent five-day change points to a shorter-term gain as well.

For investors, the distinction between the primary exchange and the displayed market-data venue matters. The quoted value is a Cboe BZX estimate, whereas Gossamer Bio is a US-listed biotechnology company traded under the ticker GOSS.

Biotech valuation remains event driven

Gossamer Bio operates in biotechnology, where share-price comparisons are closely tied to clinical, regulatory and financing milestones. The September 22, 2026 market snapshot supplies a current price and two dated performance comparisons, but it does not provide a verified current revenue, earnings or cash-flow figure for a recent reporting period.

The numerical picture is therefore concentrated in the trading data: USD 11.67 for the latest quote, 3.46 percent over five days and 12.04 percent since the start of the year, all recorded on September 22, 2026.
