Xylem is trading at $116.87, up 15.67% after-hours, following a broad U.S. market rally as midterm-election uncertainty eased.
- No verified November 4 company announcement directly explains the jump; Xylem announced investor-conference participation and published water-sector research.
- The S&P 500 rose 1.79%, Nasdaq 2.10% and Dow 3.22%.
- Earnings and lowered full-year guidance were reported October 27, not as a new November 4 catalyst.
