On Sunday, only three vessels crossed through the Strait of Hormuz, signaling continued disruptions to global oil flows and tight supply conditions. However, that benefits oil producers and refiners, as higher crude prices can lift revenues and boost margins. Several energy stocks led the sector's gains, including: - Devon Energy (DVN) - Phillips 66 (PSX) - APA (APA) - EOG Resources (EOG) - Marathon Petroleum (MPC) ## **Today's Worst-Performing Sector** Meanwhile, the sector faced the largest drawdown, with Charter Communications (CHTR) posting the largest losses. CHTR sank as several Wall Street firms turned bearish. Recently, RBC Capital cut its price target to $150 from $160, while UBS lowered its target to $140 from $235. Furthermore, Trade Desk (TTD), the worst-performing company in the S&P 500 this year, continued to fall on competition concerns, bringing its year-to-date loss to 65%. Notable communication services stocks trading lower include: - Charter Communications (CHTR) - Trade Desk (TTD) - Meta Platforms (META) - TKO Group (TKO) - Netflix (NFLX) ### Related Stocks - [CHTR.US](https://longbridge.com/en/quote/CHTR.US.md) - [PSX.US](https://longbridge.com/en/quote/PSX.US.md) - [TTD.US](https://longbridge.com/en/quote/TTD.US.md) - [DVN.US](https://longbridge.com/en/quote/DVN.US.md) - [USO.US](https://longbridge.com/en/quote/USO.US.md) - [TTDU.US](https://longbridge.com/en/quote/TTDU.US.md) - [VOO.US](https://longbridge.com/en/quote/VOO.US.md) - [UCO.US](https://longbridge.com/en/quote/UCO.US.md) - [BNO.US](https://longbridge.com/en/quote/BNO.US.md) - [.SPX.US](https://longbridge.com/en/quote/.SPX.US.md) - [VOX.US](https://longbridge.com/en/quote/VOX.US.md) - [IYZ.US](https://longbridge.com/en/quote/IYZ.US.md) - [GUSH.US](https://longbridge.com/en/quote/GUSH.US.md) - [DRIP.US](https://longbridge.com/en/quote/DRIP.US.md) - [SPY.US](https://longbridge.com/en/quote/SPY.US.md) - [IVV.US](https://longbridge.com/en/quote/IVV.US.md) - [SPLG.US](https://longbridge.com/en/quote/SPLG.US.md) - [SPXL.US](https://longbridge.com/en/quote/SPXL.US.md) - [UPRO.US](https://longbridge.com/en/quote/UPRO.US.md) - [SSO.US](https://longbridge.com/en/quote/SSO.US.md) - [SH.US](https://longbridge.com/en/quote/SH.US.md) - [SPXS.US](https://longbridge.com/en/quote/SPXS.US.md) - [SPXU.US](https://longbridge.com/en/quote/SPXU.US.md) - [SDS.US](https://longbridge.com/en/quote/SDS.US.md) - [SPYI.US](https://longbridge.com/en/quote/SPYI.US.md) - [JEPI.US](https://longbridge.com/en/quote/JEPI.US.md) - [XYLD.US](https://longbridge.com/en/quote/XYLD.US.md) - [APA.US](https://longbridge.com/en/quote/APA.US.md) - [EOG.US](https://longbridge.com/en/quote/EOG.US.md) - [MPC.US](https://longbridge.com/en/quote/MPC.US.md) - [RY.US](https://longbridge.com/en/quote/RY.US.md) - [UBS.US](https://longbridge.com/en/quote/UBS.US.md) - [META.US](https://longbridge.com/en/quote/META.US.md) - [TKO.US](https://longbridge.com/en/quote/TKO.US.md) - [NFLX.US](https://longbridge.com/en/quote/NFLX.US.md) ## Related News & Research - [Oil prices steady as investors assess US-Iran war outlook](https://longbridge.com/en/news/296417823.md) - [North Sea Crude-WTI weakens on lower offer](https://longbridge.com/en/news/296813963.md) - [Do Wall Street Analysts Like Charter Communications Stock?](https://longbridge.com/en/news/296802361.md) - [Oil set for second weekly rise as unsettled US-Iran war crimps supply](https://longbridge.com/en/news/296555193.md) - [Oil edges up on uncertainty over exports through Hormuz](https://longbridge.com/en/news/296282399.md) --- > **Disclaimer: This article is for reference only and does not constitute any investment advice.**
