PLX stock closed at $2.43 on January 31, 2025, with a 2.10% gain during regular trading hours. The bullish view stems from Protalix BioTherapeutics becoming debt-free after repaying its 7.50% senior secured convertible promissory notes, which strengthens its balance sheet and operational stability. This financial improvement could support further growth, making $2.50 a potential short-term target.
