Owning ABB (ABB) has not been a particularly rewarding experience. While the company's decision to sell its Power Grids business to Hitachi is a sound one, and the company has attractive opportunities across its business units, a long history of underperformance relative to the opportunities available is not something investors should just ignore.
Valuation, and the idea that ABB can be/do better than this, remain the best arguments for sticking with the stock, but that's an increasingly unconvincing argument to me, and I can't really say that you should favor ABB over Eaton
