As an investor, I have made it a habit to avoid large banks in my portfolios whenever I can. With this simple trick, I have done very well, especially over the last decade. The problem with large banks is simply that they have in my view all become too large to manage and too large to be profitable. Because established high street banks have become so lethargic and complex, small challenger banks could gain market share (and might actually be worth an investment in some cases).
Good post on interesting topic! Thx!
In theory this should be THE industry for scale advantages, but it's not.
Big banks in Europe seem not the best place to invest, US might be a bit different...
