Sector ETF

See: Exchange-Traded Fund (ETF).

Pretty much every sector has an ETF. There's one for oil and gas, another for utilities, another for comestibles, another for real estate, another for tech, another for automobiles, and another for transportation. They all trade in the form of an ETF, so if you're bullish on a sector and want to ride it awhile, go long their ETF and make bank. Welcome to America.
