PIO Invesco's passport-carrying water fund: about 40 companies pulled from a Nasdaq global water index, running since 2007. The overseas counterpart to the US-focused water ETFs sitting next to it on Invesco's shelf.
Stated mandate
FIW The fund seeks returns that generally track the pre-expense price and yield of the ISE Clean Edge WaterTM Index, which covers listed companies deriving substantial revenue from potable and wastewater activities.
PIO The fund seeks to track the performance of the Nasdaq OMX Global Water Index before fees and expenses and generally invests at least 90% of its assets in securities represented by that index.
