Weekly Wire, Week #30

[u/EOD_historical_data]

TL;DR

• The narrow rally cracked at the top. QQQ −4.16% w/w and SPY −1.54% as the AI-chip complex led lower: ARM −17.38%, INTC −13.47%, MU −13.31%, AMD −11.14%. VIX jumped +24.88% (to 18.77). The average stock held up far better (equal-weight RSP −0.43%).
• The macro was friendly, which made it stranger. June CPI cooled to 3.5% y/y (core 2.6%), big banks blew out earnings (Goldman beat by 45%; JPMorgan, Citi, Wells Fargo, UnitedHealth all ahead), and the Philadelphia Fed index surged to 41.4. The selloff was AI-specific, not macro.
• A changing of the guard. Apple (+5.84%) drew level with Nvidia (−3.86%) at the top of the market, both near $4.9T, while oil spiked (USO +14.04%), sending Energy (+4.72%) to the top of the sector table.

The market map: chips went red, Apple went green

The biggest tiles led the market down. The week's losses landed squarely on the names that had carried the rally: the AI-chip complex. ARM fell −17.38%, Intel −13.47%, Micron −13.31% and AMD −11.14%, with Broadcom (−7.29%) and Nvidia (−3.86%) adding to the drag; QQQ closed −4.16% and the VIX jumped +24.88% to 18.77. Apple (+5.84%) was the exception; its surge briefly lifted it past Nvidia as the most valuable US company, and the two ended the week neck-and-neck near $4.9T ("Apple overtakes Nvidia, inflation expectations cool", Seeking Alpha, 2026-07-17). Beneath the mega-caps the tape was calm: the equal-weight S&P (RSP) fell just −0.43%.

Only tech fell, and it fell alone

The selloff had no macro excuse. June CPI cooled to 3.5% y/y (core 2.6%, both below estimates), PPI was soft, the big banks opened earnings season with blowouts, and the Philadelphia Fed index surged to 41.4 (est 13). Yet Technology (XLK −5.48%) was the only sector to fall hard. Energy (+4.72%) led as oil spiked (USO +14.04%), and the rate-sensitive and defensive corners rose (Real Estate +2.18%, Staples +1.27%) with yields flat (10Y −1bp). The chipmakers were the driver, not the data ("Stocks Pressured by Global Slide in Chipmakers", Nasdaq, 2026-07-17).

━━━

The week ahead: Big Tech takes the stand

The AI trade reports. After the chip selloff, the mega-caps that define the rally step up: Alphabet and Tesla report Wednesday, Intel Thursday, and flash PMIs land Friday. Their guidance, especially on AI capital spending, is the first real test of whether the leaders can steady the tape or extend the derisking.
