Billionaire investor Warren Buffett was a sharp critic of Donald Trump during the presidential campaign, but said in an interview broadcast by CNN Friday that he expects the stock market to continue rising.

“The stock market will be higher 10, 20 and 30 years from now and it would have been with Hillary [Clinton] and it will be with Trump,” Buffett said. Suggestions by market pundits that stocks would plunge after a Trump victory were “silly,” he said.
