Berkshire Hathaway shares posted one of their best weeks in years, soaring 9.5% and touching a record high, even though Chairman Warren Buffett's choice for the White House, Hillary Clinton, was defeated by Donald Trump.

The company’s Class A shares closed Friday at $234,860, boosting Buffett's net worth to $70.3 billion.  At least for now, he’s now the world’s third richest person, just ahead of Amazon’s Jeff Bezos. Buffett, 86, owns about 18% of Berkshire, which he has run from Omaha, NE, since 1965.

Though Berkshire owns about 90 companies, perhaps the biggest boosts came from its big positions in financial stocks – e.g., Wells Fargo and American Express. Berkshire’s 10% stake in Wells Fargo rose 16% this week despite being enmeshed in a scandal over employees who set up accounts without customers' permission.

In an interview broadcast on Friday, Buffett told CNN that Wells Fargo had a "dumb incentive system," and that its former CEO John Stumpf was a decent man who nonetheless made a "hell of a mistake" and failed to correct it.

Still, Buffett said he had not sold Wells Fargo shares.
