ETFs let you own a basket of assets with a single trade. Low cost, liquid, and transparent — available on GSE and via global brokers.
ETFs trade like stocks but give you the diversification of a mutual fund. Typically lower expense ratios and daily transparency. Ideal for building a core portfolio with broad market exposure.
Purchase through licensed stockbrokers on the GSE. You need a CSD account. Global ETFs (VOO, AFK) require a foreign brokerage account such as Interactive Brokers.
