BiomX shares surge 99.27% after-hours as Pyu Pyu Capital acquires 19.99% stake via 13D filing.

BiomX Inc. (PHGE) surged 99.27% in after-hours trading following a 13D filing disclosing Pyu Pyu Capital’s acquisition of a 19.99% stake, signaling a strategic investment and potential governance influence. The filing, which typically indicates an active shareholder, triggered heightened market speculation and tightening trading float, amplifying price momentum. While the company issued a statement confirming no undisclosed developments, the significant institutional ownership shift underscored confidence in BiomX’s phage therapy platform and pipeline potential. This move aligns with biotech sector dynamics where large stake acquisitions often drive short-term volatility, particularly in smaller-cap stocks with limited liquidity. The surge also coincided with a $3M private placement announced earlier, though the 13D filing appears the primary catalyst due to its direct impact on market perception and trading behavior.
