In a way, I quite like your attitude, although it's a bit off the wall as regards HYPing. That is, you aren't interested in water companies, or haven't bothered to check out UU because you aren't interested. I'm not being critical: I rather like the confidence.
However, for most of us, this goes contrary to what we believe, or have learned - that a water company given that it does comply with the various safety requirements, might well be added for the sake of diversity. It wouldn't necessarily fall within your bracket of diworsity, but you just aren't interested:
Interesting to reflect that many investors, amateur and professional, like water companies owing to their perceived reliability as slow but steady dividend stocks, which would fit your own brief quite well.I have enough HYP shares and they are performing fine for me.
Now I'm off to wonder whether to add Pennon as a pairing with UU
