I think PHO is pretty much what it's supposed to be. It's a diverse bunch of stocks with some leverage to water infrastructure. There will certainly be better examples of these with more elaborate research behind them. For now though PHO is a decent proxy for those without the expertise to hold individual water plays. [R2 Capital owns a small position in PHO as we continue to work in the space to find more leveraged ways to play water.]
