Indeed, his real estate purchases were all less than his annual salary. Would be strange to splurge half his net worth now, without a word. (A Bloomberg journalist got him on the phone, but he refused to give an explanation.)
Not a US tax specialist, but with regards to the taxes, it is for sure a federal long term capital gain, so taxed at 20% max. Which Harris wants to put at 28%.
Not to sniff at 8%, but I don't think these decade long Berkshire holders would time their stock transactions around a (potential) 8% extra tax?
It seems to me that a big overvaluation is the most important reason.
But since Buffett was still buying at 420 in recent quarters (before he stopped in the beginning of June), that means that 465 was around intrinsic value at that time.
Something must have happened that Buffett stopped buying afterwards (even at 400-405), and Ajit is even a major seller now at 463.
Maybe his realtime reports of some of the subsidiaries foreshadow trouble incoming for the economy.
Don't forget he is the master market timer
1969 closure of his fund, 1974 oversexed man in a whorehouse, 1987 fully in bonds just before the crash, 1999 november Fortune warning, 2008 october 'buy American', etc.
Now stopped to buy Berkshire while he bought it higher before; selling his top 2 positions Apple and Bank of America like a maniac; No more Oxy buys while he bought until last june at higher prices; Ajit selling a major stake.
I think Berkshire could be at more than 50% cash in the public portfolio by now. That is a really a lot by Berkshire standards.
All this does feel... signally.
