FDMT listed in Benzinga pre-market movers
4D Molecular Therapeutics was mentioned in a Benzinga report on stocks moving lower in Friday’s pre-market session. The article grouped FDMT with other companies like Scholastic and Zscaler, noting a generally downbeat tone among legacy education and other large-cap names. This indicates the stock was part of a broader market movement rather than reacting to a company-specific announcement.
