Exchange Traded Fund (ETF)
An exchange traded fund involves a collection of securities, such as stocks, that often tracks an underlying index, although you can invest in any number of industry sectors or use various strategies. ETFs are listed on exchanges and trade throughout the day just like ordinary stock. An ETF is a marketable security, meaning it has an associated price that allows it to be easily bought and sold.
The value of units can fall as well as rise, and you may not get back all of your original investment.
