DFVE

Here's a rephrased version of the description: Under typical operating conditions, the fund allocates a minimum of 80% of its entire investment capital—which includes its net assets plus any funds acquired through borrowing for investment purposes—to either the individual securities that constitute its benchmark index or to derivative instruments that provide comparable investment exposure to that index or its components. The fund is permitted to heavily concentrate its investments within a particular industry or cluster of industries, but only to the extent that the underlying index itself exhibits a similar weighting or focus in those specific sectors.
