On March 11, Cathie Wood, founder of ARK Invest, tweeted that the current market is digesting the final stage of a rolling recession, which will give the Trump administration and the Federal Reserve (Powell Fed) more policy adjustment space than investors expected, which may push the US economy into a "deflationary boom" in the second half of this year. Cathie Wood believes that the Federal Reserve's monetary policy will be more flexible, and the market may underestimate this potential economic rebound. A rolling recession is an economic phenomenon in which different industries and sectors experience a recession in turn, while the overall economy and job market remain relatively stable.
