BiomX shares surge 69.51% after hours as Pyu Pyu Capital acquires 19.99% stake.

BiomX Inc. surged 69.51% in after-hours trading following a 13D filing disclosing Pyu Pyu Capital’s acquisition of a 19.99% stake in the company. The filing, which indicates a strategic investment, triggered significant market speculation and buying activity, as large institutional positions often signal confidence in a company’s future prospects or operational strategy. While BiomX issued statements emphasizing no undisclosed material developments, the market’s reaction appears driven by the perceived validation of the company’s phage therapy platform and potential governance influence from the new investor. The sharp price increase aligns with typical market responses to material ownership changes in biotech firms, where investor sentiment and perceived value-creation potential heavily influence short-term momentum.
