When the U.S. stock market plummeted on Monday, Cathie Wood's Ark Investment Management bought a large amount of Tesla, Palantir, Coinbase, AMD, Tempus AI and Robinhood stocks, investing more than $70 million in total. Wood posted on social media that the current market turmoil is just the final stage of a "rolling recession." She believes that this will give the Trump administration and the Federal Reserve greater flexibility than investors expect, and this shift will pave the way for "deflationary prosperity in the second half of this year."
