The week in numbers
The strongest sector this week was Technology (XLK, +1.83%); the weakest was Health Care (XLV, -2.67%). 3 of 11 sectors finished the week higher.
Cyclical sectors (technology, consumer discretionary, industrials, financials) outpaced the defensives (in relative terms — the S&P 500 itself fell), a risk-on tilt.
The indices: S&P 500 -0.22%, Nasdaq-100 +0.68%, Dow Jones -1.24%, Russell 2000 -0.18%, S&P 500 Equal Weight -0.66%.
Equal weight and cap weight finished close together — a balanced week between the megacaps and everyone else.
