With changing government administrations potentially becoming more favorable to the energy sector and with many of the stocks in that sector trading at a discount to historical valuations, midstream stocks are shaping up to be solid long-term investments right now. Energy Transfer (NYSE: ET) owns one of the largest integrated midstream systems in the U.S., which also allows it to be one of the biggest energy arbitrageurs in the country. The company is particularly well positioned in the Permian, the most prolific oil basin in the U.S. The Permian is also home to a lot of cheap associated natural gas, giving Energy Transfer a lot of opportunity around growing power needs for artificial intelligence (AI).
