The S&P 500 fell 1% as the U.S. equity markets began the trading day with a steep selloff on Nov 5. Market capitalization across the domestic stock market declined by $700 billion within the first 10 minutes after the opening bell.
The rapid drop in valuation triggered immediate reactions from traders, some of whom reported losses as high as 10% in certain holdings. No specific cause for the morning volatility was provided in the initial reports from the trading floor.
