HF Sinclair is trading 4.07% up now at $109.70 after a broader energy-sector rally linked to sharply higher crude prices.
- Houthi attacks disrupted Saudi energy facilities, intensifying Middle East supply concerns and sending Brent and WTI to multi-week highs.
- Reuters reported Brent near $99 and WTI up 3.2% on September 8, supporting refiners and energy producers.
- No new company-specific announcement clearly explains the move; recent buyback and shelf-registration news are supportive background, while the immediate catalyst appears sector-wide.
