MasterDATA classifies each ETF into one of six Fund.Types. From their
website:
US Equity ETF: All constituents trade on a US exchange. Both ProShares and
Rydex sponsor ETFs with the objective of achieving the performance (or a
multiple of the performance) of several major US stock indexes. These ETFs
currently are included in this category despite the fact that their
constituent lists are generally not limited to US stocks.
Global Equity ETF: One or more of the constituents do not trade on a US
Exchange.
Fixed Income ETF: The constituent list contains government and / or
corporate debt instruments. ETFs with this classification will not be
considered for inclusion in MasterDATA's index / ETF compilation list.
Commodity Based ETF: This classification of ETF has no constituents but is
structured to reflect the valuation of a commodity such as gold, silver, oil
or interest rates. ETFs with this classification will not be considered for
inclusion in MasterDATA's index / ETF compilation list.
Exchange Traded Notes: A type of unsecured, unsubordinated debt security that
was first issued by Barclays Bank PLC. The purpose of ETNs is to create a
type of security that combines both the aspects of bonds and exchange traded
funds (ETF). Similar to ETFs, ETNs are traded on a major exchange.
