Our read on each fund
BOILD
ERXB
In short
BOIL The only natural gas play in a leveraged energy aisle full of oil and energy stocks. BOIL aims for two times the daily move of a Bloomberg natural gas futures index, in a market known for violent swings.
ERX The 2008 original of the leveraged energy trade: 2x the daily move of the Energy Select Sector Index, built from oil-major stocks rather than crude futures. Sector-wide exposure, dialed up, for holding periods measured in days.
Stated mandate
BOIL The fund seeks daily investment results, before fees and expenses, equal to two times the daily performance of the Bloomberg Natural Gas Subindex SM.
ERX The fund seeks daily investment results, before fees and expenses, equal to 200% of the performance of the Energy Select Sector Index for a single day. It is not designed to deliver twice the index’s cumulative return over periods longer than one day.
