FutureFuel (FF) stock is currently trading at $5.52, reflecting a 5.1% gain in after-hours trading. Bulls argue that FF is undervalued, with a high earnings yield of over 15% and a dividend yield exceeding 4%, making it attractive for value investors. Additionally, its strong insider ownership (41%) and potential benefits from the new IRA 45Z tax credit could drive long-term growth once biodiesel production resumes post-maintenance in February.
