The Financial Post reports in its Friday edition that Warren Buffett is among the rare few whose personal fortunes have grown this year after U.S. President Donald Trump's tariffs triggered a stock-market sell-off. The Post's Alexandre Rajbhandari writes that Mr. Buffett's net worth has climbed $11.5-billion this year to $153.5-billion, according to the Bloomberg Billionaires Index (all figures U.S.). That is despite a $14.5-billion decline since April 2. Mr. Buffett, 94, is now the world's fourth-richest person and one of only two of the top-20 people on the list to have added to their wealth this year. The other is L'Oreal SA heiress Françoise Bettencourt Meyers, who gained $1.8-billion and stands at No. 19 on Bloomberg's ranking. The world's 500 richest people lost more than $500-billion in the two trading sessions that followed Mr. Trump's announcement. Elon Musk, who remains the world's richest person, lost $134.7-billion so far this year. His fortune fell to $297.8-billion on Monday, marking the first time his net worth has dropped below $300-billion since November. Shares of Buffett's Berkshire Hathaway have dropped 8.8 per cent since April 2, compared with the 10.7-per-cent drop for the S&P 500.
