ETFs are marketable securities that track assets such as commodities, bonds or indices. There are two types of ETFs available in Fondex: PowerShares and iShares. PowerShares cover multiple market indices as well as the commodities market. Each iShares fund tracks a bond or stock market index. ETFs trading resembles stock and other CFDs trading in the sense that you can hold both a long and short position, use leverage and apply similar risk management strategies.
