You can't make this up: At 6:00 PM ET, US stock market futures opened for the first time since Nvidia CEO Jensen Huang admitted to a "relationship" with a Chinese spy. By 6:01 PM ET, S&P 500 futures had erased an implied -$300 billion in market cap. Then, by 6:07 PM ET, all losses were erased and S&P 500 futures turned green, adding back an implied +$350 billion in market cap as traders bought the dip. That's a $650 billion swing in implied market cap due to a CEO's relationship. We all just witnessed the strangest record in stock market history.
