(Bloomberg) -- Warren Buffett just can't stop making money, even in a week where he gave $3.4 billion to charity.
The Berkshire Hathaway Inc. chairman added $4 billion to his fortune Wednesday after the conglomerate removed a cap on stock buybacks. The shares rose 5.1 percent, the most in almost seven years, lifting his fortune to $83.1 billion. His wealth dropped below $80 billion on Tuesday, after announcing the latest gift.
Buffett, 87, ranks fourth on the Bloomberg Billionaires Index.
