USA Stock market week ending 09/04/26

  • SPY — SPDR S&P 500 ETF Trust: +0.1% — The broad large-cap market finished essentially flat for the week, with gains earlier in the week offset by Friday’s decline following a stronger-than-expected jobs report.

  • ^IXIC — Nasdaq Composite: +0.4% — Technology stocks helped the Nasdaq finish modestly higher despite Friday’s pullback, with semiconductors outperforming while software stocks lagged.

  • IWM — iShares Russell 2000 ETF: +0.0% — Small-cap stocks finished essentially unchanged, reflecting continued sensitivity to interest-rate expectations and economic data.

  • Tue 9/8: NFIB Small Business Optimism Index (August) at 6:00 AM ET; Consumer Credit (July) at 3:00 PM ET. The data provide a look at small-business sentiment and household borrowing.
