Castle Investment founder Griffin: Looking back at the recent tariff storm, holding cash may be the best choice.

With the temporary ceasefire in the trade war causing the market to soar, Castle Investment founder Ken Griffin looks back on the past month and believes that it would have been better to hold cash and wait. "For fundamental investors, this period has been very challenging because the value of the companies we invest in is largely influenced by the rapidly changing policies in Washington," the 56-year-old Griffin said in an interview on Monday evening. "Looking back, holding cash might have been the best way to get through this period. But this goes against our culture of always trying to be proactive and always trying to find ways to create value in the market," the billionaire said.
