I just looked at its holdings, though, and it's mostly in cash with a giant -30% short on NEM (Newmont gold miner). The next biggest short is -13% on FE (FirstEnergy). The biggest regular holding is WST at 1.59%. Not sure why they'd make such a massive negative bet on a company that quite sound.
Their strategy: "The index is designed to select the companies for a long position that have the highest probability of increasing their dividend in a 12-month period and select the companies for a short position that have the highest probability of decreasing their dividend in a 12-month period."
