Deep DiveToday's Market Movers
Chip and AI stocks drag Nasdaq to its worst week since June

Why It Matters
Worries about how AI buildouts are financed are weighing on the stock market's biggest names, and those names carry a lot of weight in the major indexes. This week's earnings reports are the next test. For background on the debate, read Are We in Another AI Bubble? A Beginner's Guide, or see our stock market glossary for terms like futures.

Rates

Commodities
Little direct effect; gold held near $4,170 an ounce.
Hot inflation data keeps the Fed in focus, but Warsh gives no hint on October
What Happened
US Treasury yields held steady on Friday after a week of hotter-than-expected inflation reports, with September's consumer price index rising 0.6% on the month and 3.7% on the year, against forecasts of 3.6%. The producer price index jumped 6.3% from a year earlier, above the 5.5% forecast. Fed Chair Kevin Warsh declined to signal what the Fed will do at its October meeting. After his comments, traders cut the odds of an October hike to roughly 15%, while a December hike stayed near 89%. Industrial capacity use rose to 76.9%, above the 76.5% forecast.
Why It Matters
Higher inflation raises the odds that borrowing costs stay high. The Fed raised rates in September to a 3.75%-4% range, so another move is possible. To see how the Fed got here, read why the Fed might raise rates, and learn why stocks can rise even when interest rates are high.
Market Impact
Equities
Rate worries added pressure on growth stocks.
Rates
2-year yield fell more than 3 basis points to 4.715%; 10-year was at 5.085% and 30-year at 5.434% on Friday.
FX
Dollar edged lower as traders trimmed bets on a near-term Fed hike.
Commodities
Gold held near $4,170 an ounce.
Oil slips from five-month high after Trump waives Russian fuel sanctions
What Happened
Brent crude futures slipped about 1% to $108.80 a barrel early Monday, after settling Friday at their highest level since May 19. President Donald Trump waived sanctions and tariffs on Russian fuel exports, which could mean more Russian supply. US crude was at $101.18. Oil has dropped despite continued tanker attacks in the Middle East.
Why It Matters
Oil prices feed straight into inflation, and inflation drives what the Fed does. Both benchmarks are up more than 40% this year, so supply news moves markets quickly. For more on how conflict shapes crude, see Oil Prices During War: The Strait of Hormuz Explained.
Market Impact
Equities
Energy shares may feel the pull of lower crude; broad effect small so far.
Rates
Lower oil could ease inflation worries and pressure on long-term yields.
FX
Little changed; the dollar index was near unchanged on Monday.
Commodities
Brent fell about 1% to $108.80 a barrel and WTI fell 0.2% to $101.18 in early Asian trade Monday.
Retail sales and jobless claims show the US consumer is holding up
What Happened
US retail sales for September rose 0.8%, the Commerce Department data showed. Initial jobless claims edged up to 199,000. Both readings came in the same week as the hotter inflation reports.
Why It Matters
Steady spending and few layoffs give the Fed less reason to ease up on inflation. That keeps rate-hike talk alive.
Market Impact
Equities
Mixed; solid spending helps consumer firms but adds to rate worries.
Rates
Strong demand supports the case that rates stay high.
FX
Limited effect.
Commodities
Limited effect.
Big tech earnings week begins as Meta, Tesla and Netflix prepare to report
What Happened
A busy week of earnings starts after the AI-led selloff, with Netflix reporting Tuesday, October 20, as analysts expect earnings of about $0.82 a share versus $0.59 a year ago. Meta and Tesla report Wednesday, October 21, after the close, along with IBM, Texas Instruments, Lam Research and SAP. Meta is expected to report revenue of about $63 billion, roughly 23% higher than a year earlier.
Why It Matters
Investors want to see how much AI spending is paying off. Results from chip and software firms could shape how the Nasdaq trades after its worst week since June.
Market Impact
Equities
Six tech firms worth more than $200 billion report by Wednesday after the close.
Rates
Limited effect.
FX
Limited effect.
Commodities
Limited effect.
Historical Perspective
Similar Event
The summer 2026 AI-stock pullback, when tech shares fell sharply in June and July before partly recovering.
What Happened Then
Many stocks are still above their summer lows. Selloffs tied to AI worries have cooled before when earnings showed spending was holding up. They have also lasted longer when funding worries grew, so company results this week matter.
What to Watch Next
- →October 20, after the close ET: Netflix third-quarter earnings (prior: earnings of $0.59 a share in the year-ago quarter; analysts expect about $0.82)
- →October 21, after the close ET: Tesla third-quarter earnings (prior: third-quarter deliveries of 486,532 vehicles, above estimates of about 461,000)
- →October 28, 2:00 p.m. ET: Federal Reserve interest rate decision (prior: target range of 3.75%-4%, after the September hike)

Key Uncertainties
Monday's regular session had not closed when this was written, so the Monday moves cited are futures and early-trading moves, not closing figures. Some outlets differ slightly on Friday's Nasdaq drop (2.1% to 2.5%); the Associated Press figure is used. The effect of the Russian sanctions waiver on oil supply is still unclear.
