Diversification

I was emailing with a reader about diversification and I thought I should share my view on the matter.
I would not diversify just for the sake of being diversified. The only people it benefits is your money manager, it makes his/her MUM higher. (money under management)
Why let your money sit in a asset class that is dead or broken. The point is to make your money work smarter, so you dont have to work harder.
Now if you end up being diversified because your buying solid company's at discounts, because the market is willing to give them to you at discounts, then that is acceptable. However one must not get complacent and let your diversification take your eye off the ball.
That is how I approach my investments.
