Surf Air shares surge 10.87% premarket on Bernstein report citing huge upside and insider buying by co-founder and chairman.

Surf Air Mobility (SRFM) rose 10.87% in premarket trading, driven by recent developments including the company’s filing of a Form S-1 registration statement for a $100 million funding round led by Gem Global Yield LLC, announced on September 19. This filing, coupled with the co-founder and chairman’s open-market share purchase on September 18, signaled renewed investor confidence. Additionally, the publication of an updated investor presentation on September 21 highlighted strategic progress, reinforcing the stock’s upward momentum. While a "laser breakthrough" narrative cited in some reports suggested speculative upside, the immediate catalysts were concrete capital-raising actions and insider buying, which align with the premarket rally.
