On the surface, today's index declines (-0.3% to -0.6%) look unremarkable. But underneath, there's a signal worth flagging: Alphabet and Oracle — the two names most closely tied to the AI infrastructure buildout — both fell hard on the same day for the same reason, expanding leverage and negative free cash flow. That looks less like idiosyncratic company news and more like the market starting to ask a bigger question: how much patience does it have left for the AI capex cycle? The gap between a Fear & Greed reading still stuck at 63 (Greed) and individual mega-caps cracking suggests the market hasn't yet decided whether to trust index-level optimism or stock-level valuation caution. Tomorrow's CPI print may be the catalyst that tips that balance one way or the other — arguably the week's most important inflection point.
📊 Top Movers
🧭 Sector Performance
🇰🇷 Korean Investor Perspective
It was a doubly frustrating session for Korean investors. The KOSPI fell 0.95% on weakness in large-cap semiconductor names like SK hynix, while US markets — including leveraged semiconductor ETFs, a favorite among Korean retail investors (nicknamed 'seohak-gaemi,' or overseas-stock ants) buying US equities — pulled back in tandem. One silver lining: Micron (MU) rose 0.87%, showing the memory-chip trade itself held up. The USD/KRW rate rose 5.47 won to 1,412.47, which modestly cushioned won-denominated losses for unhedged holders of US equities. With Korean-favorite ETFs like QQQ (-0.34%) and TQQQ (-1.00%) also down, investors should brace for continued volatility until tomorrow's CPI release.
📊 Market Overview
All three major U.S. indices closed lower on August 11, 2026. The S&P 500 fell 24.91 points (-0.32%) to 7,728.20, the Nasdaq Composite dropped 159.91 points (-0.60%) to 26,445.45, and the Dow Jones Industrial Average shed 184.13 points (-0.34%) to 53,791.85. All three benchmarks pulled back after touching record highs just last week.
The decline was driven by a stalled US-Iran negotiation over reopening the Strait of Hormuz and cautious positioning ahead of the July Consumer Price Index (CPI) report, due the next morning at 8:30 a.m. ET. Large-cap technology names led the drop, dragging the Nasdaq lower in particular. Selling was concentrated in AI-infrastructure-linked names — Alphabet (-3.84%), Oracle (-3.69%), and Adobe (-3.39%) — while defensive and cyclical sectors like energy and utilities held up relatively well on the back of rising oil prices.
The CNN Fear & Greed Index registered 63 (Greed), still reflecting broadly optimistic sentiment even as the intraday tape showed a pullback pressured by macro uncertainty — Iran risk and the looming CPI print — highlighting a notable disconnect between headline sentiment and the day's actual price action.
🔑 Key Issues
1. US-Iran Strait of Hormuz Talks Stall, Oil Prices Rise Peace talks between the US and Iran over reopening the Strait of Hormuz remained deadlocked, keeping oil prices elevated after they had already jumped to multi-day highs earlier in the week. WTI crude rose 1.64% to $83.48 a barrel, while Brent held above $87. Despite an April ceasefire and a June memorandum of understanding, conflict flared back up in July after Iranian forces resumed attacks on commercial shipping, and the Strait of Hormuz remains the central sticking point. Energy (XLE +1.25%) was the day's top-performing sector as a result.
2. Alphabet Slides 3.84% on Capex and Debt-Load Concerns Google parent Alphabet fell 3.84%. The company raised its 2026 capital expenditure guidance to $195–205 billion, with quarterly capex up 100% year-over-year to $44.9 billion. That surge pushed free cash flow negative for the first time ever, stoking investor concern over near-term margin compression. Alphabet also closed a $25 billion unsecured senior notes offering with maturities spanning 2028–2066, expanding leverage, while a coalition of roughly 300 French publishers filed an antitrust complaint alleging Google's AI Overviews unfairly divert news traffic.
3. Honeywell Plunges 5.27% on Steep 2026 Guidance Cut Honeywell posted the day's steepest decline after issuing its first guidance since spinning off its aerospace division. The company guided full-year 2026 EPS of $8.05–$8.35 and revenue of $19.8–$20.0 billion, well below the pre-spinoff consensus of $10.78 EPS and $24.1 billion revenue. Mechanical-parts supply chain bottlenecks forced a shift toward lower-margin original equipment deliveries over higher-margin aftermarket work, and roughly $100 million in one-time separation costs further weighed on the outlook.
4. Oracle Falls Despite TikTok Ban Lift, Dragged by Broad AI-Infrastructure Weakness The Trump administration lifted the federal TikTok ban the same day. Though Oracle leads the consortium that acquired majority control of TikTok — ostensibly good news — its shares still fell 3.69%. Investors instead focused on Oracle's expanding balance-sheet leverage, negative free cash flow, and credit-rating pressure tied to its AI data center buildout, echoing the broader valuation reset that has hit AI infrastructure stocks over the past month.
5. Markets Mark Time Ahead of Wednesday's CPI Print July CPI is due Wednesday at 8:30 a.m. ET, with headline inflation expected to ease slightly to 3.4% year-over-year from June's 3.5%, and core CPI forecast to rise 0.24% month-over-month. Art Hogan, chief market strategist at B. Riley Wealth, noted that the Fed will have to weigh both its full-employment and price-stability mandates, making the monetary policy picture more complicated. The CPI outcome could shape the path to a September rate decision, keeping markets in a holding pattern.

🚀 SPCX (SpaceX) Update
SPCX (SpaceX) closed down 3.93% at $133.29, giving back a sizable portion of the 11% rally sparked by Argus's ratings upgrade on August 7. The stock has now fallen for a second straight session. Around midday, a Falcon 9 rocket carrying 29 Starlink satellites launched from Cape Canaveral, but the event provided little support for the share price. Instead, renewed concerns about oversupply ahead of an upcoming lockup expiration on August 20 — roughly 320 million shares, equal to 3.4 times average daily trading volume — appear to have driven selling pressure. Given the stock's history of sharp swings since its listing, investors should watch for elevated volatility around the lockup date.
⚠️ Investor Caution
While the headline index declines were modest (-0.3% to -0.6%), selling was concentrated in large-cap AI infrastructure names — Alphabet, Oracle, Adobe — reviving concerns about tech valuations. Both Alphabet and Oracle share a common thread of negative free cash flow and expanding leverage, suggesting the market's patience with the AI capex cycle is being tested. At the same time, the Strait of Hormuz standoff carries both upside risk for oil prices and the potential to reignite inflation until a deal is reached, which could amplify volatility alongside tomorrow's CPI print. With earnings season entering its later innings, sharp single-stock drops driven by disappointing guidance — as seen with Honeywell — also remain a live risk.
👁 Tomorrow's Key Watchpoints
- July CPI release (Wednesday, 8:30 a.m. ET) — Consensus calls for headline inflation of 3.4% YoY and core CPI up 0.24% month-over-month. A hotter-than-expected print could revive September rate-hike concerns and add further pressure to tech stocks.
- S&P 500's 7,700 support level — After two consecutive down sessions pulled the index back toward 7,700, whether it holds this level could determine the near-term trend.
- Cisco (CSCO) earnings (after the close on the 12th) — The Street expects EPS of $1.17 (+18% YoY) on revenue of $16.83 billion, with attention on whether the company extends its eight-quarter beat streak and raises its AI infrastructure order guidance (currently $9 billion).
- Whether AI infrastructure names like Alphabet and Oracle extend their decline — Watch whether today's drop was a one-off pullback or the start of a broader AI valuation reset, and whether any bounce presents a buy-the-dip opportunity.
- Whether WTI crude breaks above $85 — Additional Strait of Hormuz headline flow could push oil above the psychological $85 resistance level, adding to inflation reacceleration concerns.
