What the data says
Read-throughs anchored to Friday, October 9 closes and the separately labeled Saturday FX quote.
FRI OCT 9 CLOSE
The rebound had breadth — and a telecom fault line
At Friday's close, 311 U.S. names advanced against 177 decliners while the S&P 500 gained 0.59%. Real Estate (+1.86%) and Health Care (+1.58%) led, but Communication Services fell 1.51% as SpaceX's spectrum deal punished carriers and re-rated tower owners.
The dispersion was extreme: Crown Castle rose 15.60%, while T-Mobile fell 13.27%. That was a sector-structure reset, not a broad risk-off session.
