Today's message from the market was clear: investors are no longer asking how fast a company grows with AI, but whether it can fund that AI spending with cash. Microsoft, whose operating cash comfortably covered its capex, held roughly flat, while Alphabet, whose free cash flow turned negative, lost $500 billion in a day. Amazon's after-hours slide despite 39% AWS growth follows the same logic. Still, there's no need to read this as the end of the AI cycle. Advancers outnumbered decliners two to one, and money rotated into health care, consumer and financial names — the market didn't break, it started separating winners from losers. For now, it's a time to check portfolio resilience with a focus on companies with solid cash flow rather than on the index itself.
📊 Top Movers
🧭 Sector Performance
🇰🇷 Korean Investor Perspective
For Korean investors, a weaker won partly cushioned the stock losses. The USD/KRW rate rose 12.65 won to 1,339.46 on Yahoo Finance (Seoul's official close was 1,336.8). An unhedged QQQ (Nasdaq-100 ETF) holder's -1.42% dollar loss shrank to roughly -0.5% in won terms. Leveraged products such as TQQQ (-4.28%), however, fell too far for the currency effect to offset, and the Amazon and Intel after-hours slides may hit Friday's session. Memory optimism also cooled as Micron fell 4.98%, so Samsung Electronics and SK hynix may see profit-taking in Seoul on Friday.
📊 Market Overview
On Thursday, October 29, Wall Street closed mixed-to-lower as Alphabet's earnings shock dragged down tech broadly. The S&P 500 fell 23.59 points (-0.30%) to 7,720.39, snapping a three-day winning streak; the Nasdaq Composite slid 365.12 points (-1.38%) to 26,184.72; and the Dow Jones Industrial Average lost 132.54 points (-0.25%) to 52,342.56. The index moves look modest, but underneath was an extreme split between megacap tech and everything else.
The epicenter was Alphabet, which reported Q3 results after Wednesday's close. EPS of $2.12 fell well short of expectations (about $3.01), and above all, capital spending outran operating cash, turning quarterly free cash flow negative at -$9.1 billion. The stock plunged 12.64% to $283.82 — its largest post-earnings drop since going public — wiping out roughly $500 billion in market value in a single day. Disappointment selling in ServiceNow (-26.95%), Caterpillar (-9.25%) and Fortinet (about -20%) added to the pressure on the Nasdaq.
Market breadth, however, was actually healthy. Advancers outnumbered decliners by roughly 2-to-1 on the NYSE, and 9 of 11 sectors rose. Eli Lilly hit a record high (+6.63%), lifting the health care sector to an all-time high, while money rotated into defensive and consumer names such as Home Depot, McDonald's and Walmart. It was a textbook rotation session, showing where capital hides when doubts about AI capex grow.
🔑 Key Issues
1. Alphabet -12.6%: the return of the "AI cost scare" Alphabet's Q3 cloud revenue more than doubled year over year, but the market focused on cash flow. Quarterly capex of $51.36 billion was actually below expectations ($55.1 billion), yet free cash flow came in at -$9.07 billion versus an expected +$2.7 billion. The company kept its 2026 capex guidance of $195–205 billion and said spending will "increase significantly in 2027." Citizens downgraded the stock to Market Perform on slowing search monetization, and Bank of America cut its price target to $380 from $430. On the same day, Microsoft held up at -0.16% as $58 billion in operating cash comfortably exceeded $39.4 billion in capex — a signal that the market has begun punishing not companies that spend on AI, but companies whose cash cannot cover that spending.
2. Q3 GDP surprises at 3.4%, but inflation stirs again The Bureau of Economic Analysis' advance estimate put Q3 GDP growth at a 3.4% annualized rate, above both Q2 (2.2%) and expectations (3.2%), with investment, consumer spending and government spending all contributing. September PCE prices, released the same day, rose 0.5% month over month and 3.6% year over year, faster than August's 3.4%, while core PCE rose 0.3% m/m (0.32% unrounded) and 3.1% y/y, in line with estimates. Inflation-adjusted spending, however, was flat on the month and real disposable income fell 0.3% — a mixed picture of strong growth but shrinking household purchasing power. Coming right after the Fed held rates with two dissents in favor of a hike, markets could not fully rule out further tightening in December.
3. ServiceNow -27% reignites fears of AI eating software ServiceNow beat the top of its guidance with Q3 subscription revenue of $3.988 billion (+21%), but adjusted EPS of $1.00 slightly missed expectations ($1.02) and Q4 revenue guidance fell short of consensus. The stock plunged 26.95% to $109.67. Other software names also fell, including Salesforce (-4.63%), Oracle (-3.45%) and Snowflake (-2.84%). The structural worry that AI agents will cannibalize traditional SaaS seat revenue was priced back in, more than the results themselves.
4. Caterpillar -9.25%: strong quarter, but a flat outlook and tariff costs Caterpillar beat with adjusted EPS of $7.20 (vs. $7.08 expected) and revenue of $20.7 billion, and its backlog hit a record $78.1 billion. But it kept its annual sales growth outlook in the "mid-to-high teens," below the roughly 18% the market hoped for, and flagged $600 million in Q4 tariff costs (about $2.2 billion for the full year). Having rallied as an AI data-center power play, the stock suffered heavy disappointment selling, falling 9.25%.
5. After the close: Amazon and Intel slide in extended trading Amazon's AWS revenue rose 39% to $46.0 billion, its fastest growth in nearly five years, but EPS of $1.89 missed expectations ($1.96) and advertising revenue ($19.64 billion) trailed estimates ($20.82 billion). With trailing-twelve-month free cash flow turning negative, the stock fell about 6.7% after hours on top of a 4.25% regular-session decline. Intel beat handily with adjusted EPS of $0.52 (vs. $0.40), but Q4 revenue guidance of $15–16 billion missed expectations (about $17 billion), and the company said the PC slump will last through the first half of next year. Shares plunged roughly 17% after hours.

🌍 Global Markets
- Europe STOXX 600: 649.11 (+0.77%). The European Central Bank unanimously held its deposit rate at 2.50%, and the tech-light European index actually gained.
- Dollar Index (DXY): 101.90 (-0.28%). The dollar eased slightly alongside lower Treasury yields.
- 10-Year U.S. Treasury Yield: 4.99% (-6bp). Risk-off demand pushed it back below 5%.
- WTI Crude: $102.86 per barrel (+0.08%). Oil above $100 remains an inflation headwind.

🚀 SPCX (SpaceX) Update
SPCX fell 0.92% to $143.89, extending its decline to a second day. After sliding 2.25% on Wednesday as up to 1.3 billion locked-up shares were released, the stock continued to drift toward its $135 IPO price. With Q4 capex guided at $35–40 billion, the same scrutiny the market applied to Alphabet and Amazon — whether massive investment is eating into cash flow — is weighing on SPCX as well. Whether it holds near the IPO price is the near-term point to watch.
⚠️ Investor Cautions
The key lesson of the day is that "AI revenue growth" alone can no longer protect a stock. Alphabet Cloud (over +100%) and Amazon AWS (+39%) both posted record-level growth, but once free cash flow turned negative, the market sold relentlessly. Investors concentrated in Nasdaq-100 trackers (QQQ, TQQQ) may face elevated volatility for a while. The 3x-leveraged TQQQ fell 4.28% on the day, and further losses are possible once the Amazon and Intel after-hours slides are reflected at Friday's open.
Macro caution is warranted too. Growth (3.4%) is strong, but with headline PCE back up to 3.6% and oil above $100, hopes for Fed rate cuts have effectively vanished. With two dissents in favor of a hike at Wednesday's FOMC, strong jobs or wage data could revive a December-hike scenario.
👁 What to Watch Tomorrow
- Amazon and Intel at the open: They fell about 6.7% and roughly 17% after hours, respectively. Whether Amazon holds $230 and Intel holds $80 is the first test of tech sentiment. If they trim losses during the regular session, it could be read as "peak earnings fear."
- Nasdaq 26,000 support: The index closed at 26,184, less than 1% above 26,000. A break would raise the odds of retesting this month's lows, while the S&P 500 is showing relative resilience above 7,700.
- Q3 Employment Cost Index (8:30 ET): A gauge of wage pressure. With PCE inflation re-accelerating, a hotter-than-expected print could push yields up and add pressure on tech.
- ExxonMobil and AbbVie earnings (pre-market): ExxonMobil's EPS consensus is about $4.03. Energy earnings in the $100-oil era and AbbVie's guidance, which could extend the health care rally, will hint at how durable the rotation is.
- Will the 10-year yield retake 5%?: It barely slipped to 4.99%. A move back above 5% could rattle richly valued growth stocks again.
