The PowerShares Water Resources Portfolio is the choice of not only Mr. Woyat, but also Larry Berman, chief investment officer of ETF Capital Management in Toronto. Mr. Berman cites this ETF's liquidity – it generates by far the highest trading volumes among water ETFs – and its mix of big and small corporate names. The management expense ratio is 0.7 per cent, which is somewhat pricey for an ETF but still far lower than mutual funds.
