Chip ETF's July Whiplash: From Record-Setting Rout to a Fragile Rebound

Global chip ETF swings from 17% loss to gains as Amazon hikes AI spend to $220B, Samsung and Arm post record results, easing fears of an AI capex slowdown.

The iShares MSCI Global Semiconductors UCITS ETF has spent the past month careening between extremes. After shedding roughly 17 percent of its value in the 30 days leading into early August, the fund clawed back 1.54 percent on Friday to settle at 16.47 euros. Days earlier, it had posted a more dramatic snapback — a near-5 percent surge in the technology sector of the S&P 500, its strongest single-day gain since April 2025, with the ETF itself jumping more than 5 percent at one point before settling at 16.25 euros.

What's driving the turbulence isn't a breakdown in the AI trade. It's a market trying to figure out whether the enormous capital commitments behind artificial intelligence are built to last.

Amazon's $220 Billion Bet Shifts the Mood

The most recent catalyst came from Seattle. Amazon blew past expectations on Friday and lifted its 2026 AI infrastructure spending plan to $220 billion, up from a previously announced $200 billion. The e-commerce and cloud giant's AWS division posted robust growth, and the ripple effects were immediate: Micron, SanDisk, AMD and Intel all ticked higher in pre-market trading.

That momentum had been building since Thursday, when strong results from Microsoft, Samsung and Lam Research started to turn the tide. The single most striking move came from memory makers — Micron and SanDisk each exploded higher by 18.4 percent and 26 percent respectively in a single session.

Samsung and Arm Deliver Record Numbers

The fundamentals underneath the rebound are substantial. Samsung Electronics reported final second-quarter results on July 31, 2026, posting record revenue of 171.5 trillion won and an all-time-high operating profit of 89.5 trillion won. The engine was demand for High-Bandwidth Memory and DDR5 storage — the backbone components of modern AI systems. Samsung also guided that HBM4 sales should more than triple in the third quarter. Its mobile division continues to wrestle with cost pressures, but that business is now a sideshow to the memory story.

Arm Holdings followed suit, reporting on July 29 for its fiscal first quarter of 2027. Revenue came in at $1.29 billion, up 22 percent year over year, with licensing revenue growing at the same clip to $715 million on the back of Arm's expanding footprint in cloud infrastructure. The stock initially dipped on a conservative full-year outlook, but the structural growth in data-center licensing remains intact.

The July Meltdown That Preceded the Recovery

The rebound masks how brutal the preceding weeks had been. AMD lost roughly $110 billion in market value during the selloff; Taiwan Semiconductor Manufacturing (TSMC) shed $119 billion. Morningstar's chief equity strategist characterized the decline primarily as a sentiment-driven phenomenon rather than a fundamental deterioration, with investors fretting over a possible end to the AI investment boom and intensifying competition from China.

Asian suppliers absorbed the worst of the damage. SK Hynix at one point collapsed 14.65 percent, while Samsung Electronics dropped more than 13 percent. European equipment makers weren't spared either: ASML fell over 8 percent following reports of a Chinese immersion lithography machine — technology where ASML has long held dominance.

The earnings season added its own friction. Qualcomm disappointed with mixed quarterly numbers, posting earnings per share of $2.21, just shy of the $2.23 analysts had penciled in. The stock dropped more than 7 percent.

A Fund Caught Between Record Gains and Deep Drawdown

The ETF's trajectory tells the story of a sector in emotional whiplash. On a seven-day view, the fund was still down 5.91 percent; over 30 days, the deficit stretched to 18.02 percent. Yet the year-to-date gain remains a stout 70.05 percent, and the fund sits 24.51 percent below its 52-week high of 21.52 euros, reached on June 22, 2026 — a gap that underscores just how quickly sentiment can pivot.

The primary article's data shows a slightly different snapshot: a 23.49 percent drawdown from the 21.52-euro high reached in June, with year-to-date performance at 72.33 percent. Either way, the long-term uptrend has not been broken, though short-term volatility remains elevated.

The fund's top holdings span the full chip value chain. Micron Technology leads at 9.62 percent, followed by AMD at 8.17 percent, TSMC at 6.33 percent, Broadcom at 5.35 percent and Nvidia at 5.29 percent. ASML, Taiwan Semiconductor and Micron also feature prominently, meaning the ETF's performance is directly tied to the two groups that swung most violently this week: chip designers and memory manufacturers.

The Skepticism Beneath the Surface

Friday's optimism hasn't erased the underlying nervousness. In the week ending June 24, roughly $11 billion flowed out of US semiconductor funds — the largest weekly outflow this century, according to LSEG Lipper data. Meanwhile, Bank of America projects worldwide cloud and AI infrastructure investment could approach $1.5 trillion by 2027, a 40 to 50 percent increase from the prior year.

Strategists are split on what comes next. Aberdeen sees the selloff as a buying opportunity, arguing valuations have become more attractive. Standard Chartered's chief investment officer for equities points to analyst reports anticipating a peak in memory prices by 2027 — though he concedes the risk-reward profile has improved at current levels.

AMD's Moment of Truth

All eyes now turn to Advanced Micro Devices, which reports second-quarter results on Tuesday, August 4, 2026. In May, AMD posted a 57 percent surge in data-center revenue, fueled by the ramp of its own AI accelerators. Investors want to see whether that pace carried into the second quarter.

Should AMD confirm the growth trajectory from the prior quarter, it would reinforce the sector's stabilization. The coming weeks will bring more earnings from across the industry, and the durability of the cloud giants' spending plans will face further scrutiny as additional hyperscalers and chipmakers update their capital expenditure outlooks. For now, the semiconductor trade remains a study in contrasts: record fundamentals, historic outflows, and a market struggling to decide which signal matters more.
