No, CTRE is not an exchange-traded fund (ETF). It is the official ticker symbol for CareTrust REIT, Inc., which is a publicly traded real estate investment trust listed on the New York Stock Exchange. While an ETF pools money from multiple investors to buy a basket of diverse securities or assets, CTRE represents direct corporate equity ownership in a single self-administered real estate company specializing in healthcare properties, skilled nursing facilities, and senior housing assets.
