Subject: Re: Brk up again, does anyone have a clue
That's about 20% (1.72 standard deviations) above its average valuation level in the last 20 years, using the "smoothed real value per share" sort of view.

It seems now might be a good time to buy-to-close my Berkshire puts. They've lost about 60% of their value, so I can buy them back at 40 cents on the dollar. If Berkshire starts getting cheap again, I should be able to sell some again. I don't mind holding them to the end and getting Berkshire shares for $450 6 months from now, but it seems less likely to happen now that the price is higher.
