SPXT launched in September 2015 as part of the ex-sector suite from ProShares, which seeks to represent the US large-cap space without exposure to a specific sector. The fund starts with the S&P 500 index constituents. From this selection universe, companies are classified by sector according to GICS and those under tech are excluded from the portfolio. Selected securities are market-cap-weighted and rebalanced quarterly. SPXT might be used either speculatively - when you want to bet on the underperformance of the technology sector, or complementary - when you already have large positions in the tech industry, and are looking to diversify.
