The S&P just went from a low of 4853 points to 5166 points. That is a swing of 313 points or 6.45%.
This beats the previous record, which was set last Friday, 4/5/25, at 222.24 point swing.
This is against data tracked since 1967, and certainly represents a period of insane volatility in price and information access.
