The Nasdaq Composite's four-week winning streak died loudly on Friday. The index dropped 572.99 points, or 2.1%, to 26,140.03 — sealing its worst week since June at roughly -4.4%. The S&P 500 fell 84.62 points, or 1.1%, to 7,659.44; the Dow slipped 175.28 points, or 0.3%, to 52,002.41. As the Associated Press put it: "A broad sell-off in technology companies pulled stocks lower on Wall Street Friday, capping off the market's worst week since late June."
The final leg down had no data release behind it — only silence. Fed Chair Kevin Warsh, addressing financial leaders in Bangkok, refused to tip his hand on whether the central bank will hold or hike at its October 27-28 meeting. "On Friday, Federal Reserve Chairman Kevin Warsh offered no fresh signals about potential interest rate policy moves by the Fed while attending a meeting of financial leaders in Bangkok," AP reported; the Motley Fool noted he "was tight-lipped about any further tightening measures."
Friday's session — a rotation, not a panic
Midday showed the shape: at 11:37 a.m. ET the Dow was up 0.29% at 52,327 while the S&P 500 sagged 0.34% to 7,718 and the Nasdaq had lost 1.09% to 26,419 — "as investors rotate out of tech stocks into defensive sectors," in the Fool's phrase. The afternoon only deepened the split.
Slightly more than half of S&P 500 stocks fell, but technology was a rout: all but seven of its 75 tech names closed lower. Chipmakers took the worst — Micron -5.6%, AMD -6%, Broadcom -4.5%, Intel -5.8% — stretching the semiconductor slide to eight straight sessions. Megacaps joined in: Meta -3.7%, Alphabet -2.5%.
The sharpest single-stock pain sat in AI infrastructure: CoreWeave tumbled almost 10%, stretching its five-day loss to 23% on repriced AI debt loads. Tesla fell 2.1% to $354.72 after unveiling a redesigned Roadster — an early surge on the SpaceX-derived design fully reversed by the close. Netflix dropped 2.9% after replacing chief content officer Bela Bajaria with Peter Rice, days after cutting roughly 6% of its workforce. Hut 8 slid 7% as on-chain data showed large Bitcoin transfers onto exchanges.
The winners sat where higher yields help rather than hurt. Exxon rose 2.5% and Chevron added 2.6% as Brent crude jumped 3.7% to $109.86 a barrel. Alcoa climbed 2.5% and Travelers gained 1.5% after both reported quarterly results above forecasts.
Background — how the week got here
Friday's slide was the last chapter of a week that kept handing Wall Street reasons to sell technology.
It began with the Federal Reserve. The September 16 quarter-point hike to about 3.9% — the first increase in three years — has hung over growth stocks ever since. Then came back-to-back inflation shocks: September CPI printed hot at 3.7% year-on-year on Wednesday, September PPI even hotter at 6.3% on Thursday, the fastest annual pace since December 2022. Each print raised the stakes for the October 27-28 meeting, and Warsh's Bangkok appearance was the week's last scheduled chance for guidance. He gave none.
The AI trade cracked on its own too. Modest revenue figures from Anthropic revived doubts over whether AI companies can service expansion debt with borrowing costs at multi-decade highs; CoreWeave's 23% five-day collapse became the week's emblem.
Banks were the bright spot: Goldman Sachs, JPMorgan, Morgan Stanley, Bank of America, Citigroup and Wells Fargo all beat — which is why the financial-heavy Dow finished green for a second straight week while technology bled.
Bonds told the same story in reverse: the 10-year yield ended Friday near 5.09%, down from 5.10% late Thursday, as equity selling pushed money into Treasuries. It had topped 5.30% earlier in the month — its highest since 2002. Gold firmed 0.17% to $4,177.51 by midday on the haven bid, while European and Asian markets closed higher.
Oil added a geopolitical edge: with Brent at $109.86 and US gasoline averaging $4.33 a gallon versus $3.06 a year earlier, ING strategists said markets were "pricing in a significant risk premium" around Middle East uncertainty and Hormuz oil flows.
The week in numbers
Index scoreboard — Friday, October 16
| Index | Friday close | Friday move | Weekly move |
|---|---|---|---|
| Nasdaq Composite | 26,140.03 | -2.1% (-573 pts) | ≈ -4.4% (-1,212 pts), worst since June |
| S&P 500 | 7,659.44 | -1.1% (-85 pts) | ≈ -2.0% (-154 pts) |
| Dow Jones | 52,002.41 | -0.3% (-175 pts) | Higher — 2nd straight weekly gain |
MarketRadar arithmetic: working back from the weekly point moves, last Friday's closes were approximately 27,352.51 on the Nasdaq, 7,813.04 on the S&P 500 and 51,765.32 on the Dow. The Nasdaq's four-week winning streak is over; the S&P 500's weekly drop wiped out the prior week's record-setting gains.

Rate-hike pricing (CME FedWatch): October meeting hike odds fell to 17% from 28% a day earlier after Warsh's remarks; December meeting odds run near 89%. Next decision: October 27-28.
Why it matters
The Nasdaq's roughly 4.4% weekly loss was its worst since June and ended a four-week winning streak; the S&P 500's roughly 2% drop erased the prior week's record-setting gains.
The AI-credit question is now a market question: with the 10-year at 5.09% and producer prices up 6.3% a year, funding the AI buildout is Wall Street's central anxiety — CoreWeave's 23% five-day slide is the evidence.
Warsh's silence leaves the October 27-28 meeting genuinely live: October hike pricing moved eleven points in a day on no new data, only absent guidance.
What to watch
The Fed's October 27-28 decision lands just over a week out, and any December signal carries the real weight. Watch whether the eight-session semiconductor slide finds a floor or drags the S&P 500 toward 7,600.
Earnings are the other hinge: banks carried the Dow this week, and tech results must now justify multiples the market just repriced. Another hot inflation print would reprice December further.
MarketRadar take
The tape tells two stories. The Dow's second straight weekly gain says the real economy — banks, energy, industrials — is holding up; the Nasdaq's 1,212-point slide says AI growth is no longer priced as immune to borrowing costs above 5%. The lines are arithmetic now: 26,000 on the Nasdaq and 7,600 on the S&P sit below Friday's 26,140 and 7,659, with last Friday's 27,353 and 7,813 overhead. With Warsh silent and the decision just over a week out, the market's working assumption is drift until the Fed speaks — tilted down.
