UPDATE 1-Buffett s Berkshire buys Aon, slashes Chevron and Wells Fargo Reuters 5 hrs ago
By Jonathan Stempel
May 17 (Reuters) - Berkshire Hathaway Inc said on Monday it has taken a $943 million stake in insurance brokerage Aon Plc and sold large portions of its investments in Chevron Corp and Wells Fargo & Co.
The changes were disclosed in a regulatory filing detailing Berkshire s U.S.-listed holdings as of March 31.
Berkshire also shed two smaller holdings entirely, Canada s Suncor Energy Inc and private label credit card issuer Synchrony Financial Inc.
The sales suggest that Buffett and his investment managers Todd Combs and Ted Weschler may be growing more wary of valuations as stocks regularly set new highs.
