Energy Select Sector SPDR Fund

This ETF offers exposure to the U.S. energy industry, including many of the world's largest oil producers. While XLE probably doesn't make sense for those constructing a long-term buy-and-hold portfolio, it can be potentially useful as a tactical overlay for those looking to shift exposure towards a sector that thrives when oil prices show strength. Compared to other energy options, XLE is impressive in terms of both cost efficiency and liquidity; investors can generally expect to execute at penny wide spreads. But like many funds offering exposure to the energy sector, XLE maintains some concentration issues, as a few stocks account for big chunks of the total portfolio. Those seeking to avoid this issue may like the equal weighted RYE; the alpha-seeking FXN may also be an intriguing option for energy exposure.
