I think it's ridiculous when members of this board get so precious about their valuation of Berkshire, where for example at 1.3x BV its a "buy" and at 1.5x BV it's a sell.

Those P/B sideboards have held for a long time. The price has mostly bounced around those ratios through good markets and bad markets, through a younger (old) Buffett and a really old Buffett. I would not feel comfortable standing pat with a price well outside of either side thinking that "this time is different".
