The Energy Select Sector SPDR Fund declined in recent sessions, with the broader energy sector showing mixed performance. While energy has lagged over the past year, it has recently improved to become the third-best performing sector over three months. Analysts note this relative strength may persist. Specific catalysts mentioned include Talen Energy's multi-billion dollar acquisition of natural gas assets and commentary highlighting ExxonMobil as an attractive pick within the energy sector, suggesting selective optimism among fund managers.
