Bill Gross expressed concerns regarding the impact of market instability on Gen Z investors, highlighting how the value of stocks can be heavily influenced by the decisions made by President Donald Trump. He advised investors to reconsider holding highly volatile US stocks, which are vulnerable to sudden shifts based on the President's actions. Gross's remarks were made in response to Trump's announcement of a 90-day pause on tariffs, which led to a significant surge in stock prices. He emphasized the potential risk posed by market fluctuations, particularly impacting younger investors such as millennials and Gen Z.
