ProShares S&P 500 Ex-Energy ETF(AMEX:SPXE)

SPXE launched in September 2015 as part of a suite of ex-sector funds from ProShares, which seek to represent the US large-cap space without exposure to one sector energy, in this case. The underlying index is a float-adjusted, market cap-weighted index that factors in criteria such as liquidity, price, market capitalization and financial viability. The fund will generally invests at least 80% of its total assets in the securities that make up the Index. SPXE might be used either speculatively (i.e. for avoidance of a sector likely to underperform) or in a complementary fashion (i.e. for diversification purposes).
