Chip ETF's July Whipsaw Ends With Hyperscaler Rescue — But the Memory Price Debate Lingers

Chip stocks surge after Microsoft and Amazon earnings, but record sales clash with a 24% drawdown, highlighting market volatility.

The iShares MSCI Global Semiconductors UCITS ETF closed Friday at EUR 16.27, a modest 0.27 percent gain on the day. Behind that unremarkable figure sits one of the most violent stretches the fund has endured in years — a month that saw record industry sales collide with a brutal de-rating, followed by a sharp rebound powered not by chipmakers themselves, but by their two biggest customers.

A record-setting selloff, then a two-day about-face

The damage accumulated quickly. Over the past week the fund shed 5.77 percent, and the 30-day decline reached 17.90 percent. At its worst, the ETF stood roughly 24 percent below the 52-week high of EUR 21.52 touched in June. Then came Thursday: Microsoft delivered quarterly earnings that blew past expectations, sending its shares up 15.5 percent — the stock's best session in nearly 18 years. The following day, Amazon matched the momentum, beating profit forecasts and lifting its 2026 capital expenditure guidance from $200 billion to $220 billion.

For semiconductor investors, that capex signal was the message that mattered. The hyperscalers' multibillion-dollar AI spending commitments remain intact, and with them the demand engine for chips. The Philadelphia Semiconductor Index responded by jumping 8.2 percent, snapping a five-day losing streak, while the more memory-heavy Roundhill Memory ETF surged 17 percent.

Memory names led the rebound. Sandisk rocketed 26 percent, Western Digital added more than 5 percent, and Micron gained 3.5 percent in pre-market trading. Established designers moved higher more modestly — Intel rose 4.6 percent, AMD 3 percent. The reaction in Asia was even more pronounced: South Korea's Kospi jumped a record 18 percent, SK Hynix hit its 30 percent daily limit, Taiwan's Taiex climbed 8 percent, and TSMC advanced 10 percent.

The paradox of record sales and falling prices

The rally capped a month defined by contradiction. Global semiconductor revenue hit an all-time high of $120.6 billion in May 2026, up 104.1 percent year over year — the 15th consecutive record month. Company guidance remains ebullient: Broadcom projects AI chip revenue growth of over 200 percent to $16 billion in the current quarter, while Micron targets quarterly sales of $50 billion.

Micron itself embodies the disconnect. The memory maker reported fiscal third-quarter revenue of $41.46 billion, up 345.7 percent from a year earlier and well above analyst estimates. Adjusted earnings per share came in at $25.11 versus the $20.28 consensus. CEO Sanjay Mehrotra called it a record quarter with an even stronger fourth-quarter outlook. The stock still lost over 24 percent in a month. Credo Technology, a networking chip specialist, suffered similar declines despite solid results. Strong numbers alone, it seems, are no longer sufficient.

The selloff that preceded Friday's rebound was triggered in part by fears that memory chip prices may have peaked. Sundeep Gantori, chief investment officer for equities at Standard Chartered, points to broker reports projecting peak memory prices as early as 2027. Media coverage of China's ambitions in memory chips and lithography equipment added to the anxiety. At current valuations, the mere prospect of a cyclical top proved enough to trigger selling.

Positioning, not fundamentals, drove much of the damage

Market commentators have also attributed a meaningful portion of the late-July decline to forced liquidations of AI-related positions, including by the investor Situational Awareness, rather than a breakdown in the AI investment thesis. Several strategists argue that positioning — not a fundamental rupture — accounted for much of the volatility. Ulrike Hoffmann-Burchardi of the UBS Chief Investment Office sums up the stance: "We remain constructive on the AI growth story, but advise investors to manage concentration risk through broader diversification into more defensive tech names."

A brutal month, an intact trend

Even after the turmoil, the fund's longer-term performance remains striking. The ETF is still up 70.30 percent since the start of the year and 125.87 percent over twelve months. The July drawdown, while the sector's worst month since 2008, has not erased the structural gains — though the fund remains 24.39 percent below its June 22 peak.

The fund's broad mandate, spanning memory makers, foundries, and equipment suppliers, captures both the AI demand story and the sharper swings of individual segments. Whether the rebound holds may hinge on the next round of capital expenditure guidance from Alphabet, Amazon, and Microsoft. For now, the market remains caught between record industry fundamentals and the nagging question of when the memory cycle turns.
