Decoy Therapeutics is trading at $1.22, up 10.91%, with no company-specific announcement or catalyst found for October 29. - The company’s investor page lists September 30 as its latest press release; a news tracker lists October 19 as its most recent item. - The provided market context is broadly negative and does not explain the rise. - Shares also closed higher in the prior two sessions, but that alone does not establish a cause.
