MARKET BRIEFING · US

All three major indexes closed the week higher, yet semiconductors sat out the rally.

October 9, 2026 · Read the Korean original

Major indices

  • Dow 51,654.95 +0.83%
  • S&P 500 7,811.54 +0.59%
  • Nasdaq 27,366.17 +0.64%

What had weighed on the market all week was Treasury yields and oil, and on Friday both eased at once. Long-dated yields had climbed to 24-year highs earlier in the week before pulling back, and upward pressure on crude faded after President Trump said he would not strike Iran before the November midterm elections. The 10-year Treasury yield sat near 5.24% and West Texas Intermediate finished around $92 a barrel (Rock and Turner, Newspim). The pause in that twin climb was the foundation for the day's rebound.

The session therefore looked more like relief buying that undid the previous day's slide in AI-linked shares. The Dow rose 0.83%, the S&P 500 0.59% and the Nasdaq 0.64%, leaving all three with weekly gains, and the S&P 500 ended just shy of its record close (TheStreet, Investing.com). Risk appetite returned ahead of earnings season, which opens next week with the big US banks.

The story that actually drove the day, though, was SpaceX rather than the indexes. SpaceX agreed to acquire a nationwide portfolio of 800 MHz low-band spectrum from Grain Management, bringing commercial Starlink Mobile service a step closer, and Verizon suffered its worst day since July 2002 while T-Mobile and AT&T fell by close to double digits (CNBC). Tower operators such as Crown Castle and American Tower rose instead, on the reading that demand for their sites would grow. Semiconductors, by contrast, sat out the rally: the Philadelphia Semiconductor Index slipped, failing to recover the damage from the prior day's dispute over OpenAI's revenue (TheStreet Pro, MarketScholars).

When Korean trading resumes, telecom carriers may face the same question asked in the US: how far satellite service can erode incumbent mobile operators' share. Korea has fewer carriers and a different regulatory setting, so the read-across is less direct, but it can still weigh on sentiment. Semiconductors lack a fresh catalyst now that their US peers have paused, while the drop in crude reads as relief on input costs for chemicals and refining.

The confirmed facts are the SpaceX spectrum agreement, the gains in all three indexes and the slide in telecom shares. The deal still needs FCC approval, so how the competitive picture actually changes remains interpretation, and JPMorgan judged the near-term risk to US wireless incumbents to be limited (CBS News, CNBC).

Korean industries to watch today

  • Telecom & networks · Starlink Mobile's spectrum deal may spread satellite-competition worries to telecom sentiment
  • Semiconductors · US chips sat out the rally, leaving little to lift memory and AI-chip expectations
  • Chemicals & refining · Easing crude pressure after the Iran reprieve may relieve chemical input costs
