Stocks fell across the major indexes this week as technology led the decline and defensive sectors like health care and energy held firm.

Stocks closed the week lower. The S&P 500 slipped 1.37% over the five sessions, while the tech-heavy Nasdaq dropped 2.41% as the large technology names that dominate it took the heaviest losses. The Dow proved more resilient, down 0.85%. The weakness built steadily. All three benchmarks fell into Thursday, when the S&P 500 marked its low for the week, before a Friday bounce recovered part of the ground. The S&P 500 added 0.41% on Friday alone, though one green session could not undo four days of selling. By the close, the S&P 500 stood at 7,674.37, the Dow at 53,277.01, and the Nasdaq Composite at 26,180.45.
Health care and energy led the tape
The weekly sector scoreboard tilted toward defense. Eight of the eleven S&P sector groups finished in the red. Health care (XLV) was the standout on the other side, topping the board with a 4.33% gain, much of it from a single sharp advance on Wednesday. Energy (XLE) rose 2.79%, climbing in three of the week’s five sessions, and materials (XLB) added 1.90%. The middle of the pack barely moved, with consumer staples and consumer discretionary each finishing within a quarter percent of flat. The selling concentrated at the other end. Technology (XLK) was the worst performer, off 3.53%. Utilities (XLU) fell 3.48% and industrials (XLI) 3.36%. Communication services (XLC) and financials (XLF) each dropped more than a percent, and real estate (XLRE) edged down 0.42%.
Small caps lagged, volatility eased
Breadth favored the larger names again. The Russell 2000, tracked by IWM, fell 1.68% on the week. That left small caps behind both the Dow and the S&P 500, extending a stretch in which the group has struggled to match the megacap-heavy indexes. The split between growth and the rest defined the week: the Nasdaq’s 2.41% decline nearly tripled the Dow’s 0.85% loss, the shallowest among the majors. The S&P 500 itself traded in a narrow band, its daily closes spanning little more than a percent from Monday to Friday. Volatility, for its part, stayed subdued. The VIX ended Friday at 15.13, a reading that points to calm rather than stress in the options market. A losing week paired with volatility this low is an uncommon combination. The 10-year Treasury yield finished the week at 4.69%.
PCE and Jackson Hole headline next week
The coming week is dense with economic data, and much of it clusters on Wednesday. The Fed’s preferred inflation gauge, the PCE price index, is due that day, alongside a second estimate of second-quarter GDP and durable-goods orders. Forecasters look for the core PCE reading to rise 0.2% on the month, up from 0.1% in the prior report. Reports on personal income and spending arrive the same morning. Consumer confidence data land Tuesday. The Kansas City Fed’s Jackson Hole symposium opens toward the end of the week, a gathering markets follow for cues on the direction of interest rates. Nvidia, the largest US company by market value, reports earnings Wednesday. Each is a scheduled release, nothing more.
