The indices
The week in numbers
The strongest sector this week was Energy (XLE, +1.60%); the weakest was Communication Services (XLC, -4.35%). 8 of 11 sectors finished the week higher.
Defensive sectors (consumer staples, utilities, health care) outpaced the cyclicals (in relative terms — the S&P 500 itself fell), a risk-off tilt.
The indices: S&P 500 -0.44%, Nasdaq-100 -0.76%, Dow Jones +0.44%, Russell 2000 +1.95%, S&P 500 Equal Weight +1.14%.
The equal-weight S&P 500 beat the cap-weighted index: the average stock did better than the index, so the move was broad rather than carried by the megacaps.
Small caps (Russell 2000) beat big tech (Nasdaq-100).
