But we saved everything 🙂.

Last month, Tuchman reported that the S&P 500 dropped $800 billion in market cap in a single session, contributing to a monthly loss of $2.5 trillion and a 4% decline at the time. Earlier this year, he highlighted a two-day period when the index gained over $700 billion in value. Market swings have remained pronounced in recent weeks.
