But we saved everything 🙂.
The S&P 500 saw significant volatility, as detailed by Peter Tuchman, with the index recovering from early losses to close the day 0.44% higher. This move resulted in an increase of over $200 billion in market capitalization. Tuchman described the trading session as notably eventful and suggested a deeper discussion on the factors driving such a dramatic shift in the U.S. market.
Earlier this month, Tuchman noted the S&P 500 lost $800 billion in market capitalization in a single day, with the index down 4% over the month and total losses reaching $2.5 trillion at the time. He also reported that the index fell 1.7% in another session, wiping out $1 trillion in market value as it hit its lowest level since September 2025 during the period. These moves underscore the recent sharp swings in the S&P 500’s value.
