Warren Buffett Says Most Activist Investors Offer 'Promise of Performance'

In a conversation with friend Carol Loomis at the Fortune Most Powerful Women event Tuesday, Warren Buffett (Trades, Portfolio), CEO of Berkshire Hathaway (BRK.A)(BRK.B), spoke out about the increase in investing activism in recent years, saying he had “zero interest” in participating. Buffett said a portion of the activism “makes sense, in certain cases,” such as when corporations are mismanaged to the detriment of shareholders. The bulk of it didn’t fit into that category, though, he said.
