Charles Schwab's Jeffrey Kleintop remains bullish on European stocks, citing a strong earnings season and economic data that's beating expectations. With the U.S. and Europe set to resume trade talks, Kleintop sees potential for a breakthrough, particularly if the E.U. agrees to increase defense spending. He notes that while some are calling for an end to the U.S. economic cycle, he believes these concerns are overblown and that international markets, including Europe, still offer more attractive valuations.
