Agree, I don't know of what possible benefit this could be to investors, especially at this point in time. I suppose you could argue that these companies represent quality based on the amount of cash they distribute which is only possible with size and a dominant position in their respective economic sectors but without taking sustainability into account, it means little. History is filled with the corpses of companies that were once titans, until they weren't.  I've built a portfolio over the last 25 years that includes 10 of these names but I don't see any of them particularly as buys right now and wouldn't touch Potash or Hydro One.
