BRK's price has moved closer to fair value IMO. It occasionally happens. Fair value will continue to grow as well. Will BRK be higher a year from now, likely IMO. Will investors overlook it again at some point, of course. The value of BRK has not changed dramatically in 2026, but it is higher than when the year began. Stocks move as perceptions change. When BRK is materially overvalued then I will make some changes in my holdings. I don't believe that the current stock price puts BRK in an overvalued situation.

If it moves 30% up in a year, then my views would change.

I continue to sell forward calls against my position. I have them from $570 to $740 from Jan 2027 to Jan 2028. I consider fair value to be in the $575 range as I type. Of course I could be off by 5% or more in either direction. But $556 is not grossly overvalued IMO.
