A 4.80% single-session decline in the Goldman Sachs Magnificent Seven basket is the group's largest one-day loss in five years, Goldman Sachs reported. Five years covers roughly 1,250 trading sessions, at 250 per year. The 4.80% figure is the worst single-session result the basket has produced across that entire window.
The five-year record
Goldman Sachs compiles and tracks the Magnificent Seven as a cohort basket. The bank designated the 4.80% one-day drop a five-year record for the group. No prior session in that lookback window produced a larger aggregate daily loss.
