The XLI fell 0.41% (−0.70 pts) on the week, but 46 of 83 members went the other way. CAT and DE dragged the tape lower, contributing more than the entire move.
EATON CORP PLC and NORDSON CORP moved almost identically (−1.49% vs −1.61%), yet ETN moved the XLI 10.8× as much. In a cap-weighted index, the bigger company's weight turns the same percentage move into far more points.
