These are the best-performing stock sectors of 2026

U.S. equities have seen a sharp divide in sector performance in 2026, with geopolitical tensions and artificial intelligence (AI) investment influencing returns. Energy leads with a 49.09% year-to-date gain, supported by supply disruptions and rising oil prices amid the U.S.-Iran conflict. In early October, the S&P 500 energy sector was already up more than 42%, outperforming all other sectors as the conflict drove oil prices higher. Higher crude prices can boost oil producers’ revenue and cash flow, although further gains will depend on developments in the Middle East and global supply and demand.
