Ya Buffet sold off a crap ton of stocks, he was all in on expecting this
He dumped about half of his shares of Apple.
Berkshire Hathaway has been holding its largest cash position ever. Meaning he(they) correctly perceived that the entire market was OVERPRICED. That it was overdue for a correction.
Do not blame him for being right.
The Bank of Japan raised interest rates for the first time since 2007. This caused the value of the Yen to go up in comparison to other currencies like the US dollar. In simple terms this meant for 14 years you could borrow $100 dollars and at the end of the year repay $100.40 dollars. So, banks could borrow $10 Million US dollars worth of YEN and invest it in something like US Treasuries making 5.3 %. Basically, making 5% on someone else money. This has all changed.
So, big investors have to now sell the equities and repay the loan to the bank of Japan because of a margin call. Those investments could have been in stocks, gold, Bitcoin, US Treasuries, futures, basically EVERYTHING.
