Memory Constraints and Earnings Jitters Weigh on AI-Focused ETF

Broadcom's weak AI guidance and memory shortage warnings hit the Xtrackers AI & Big Data ETF, which holds 18% in memory stocks. Focus shifts to CPI and Fed.

The Xtrackers Artificial Intelligence & Big Data UCITS ETF ended a turbulent week at €199.46, nursing a 7.25% single-day loss on Friday and a 6.03% weekly decline. The sell-off came as investors digested two contradictory forces: a guidance miss from Broadcom that knocked sentiment, and a growing industry alert about memory chip shortages that could reshape the ETF's portfolio dynamics.

Broadcom’s second-quarter numbers for fiscal 2026 initially looked solid — revenue of $22.19 billion, up 48% from a year earlier, with AI chip revenue surging 143% to $10.8 billion. But the market turned hostile when the company guided for third-quarter AI semiconductor sales of $16 billion, well shy of the $17.2 billion analysts had penciled in. To make matters worse, the full-year AI revenue target stayed at $56 billion, dashing hopes for an upgrade. Broadcom is a heavyweight in the underlying index, so the stock's slide hit the ETF hard.

Yet that is only half the story. A separate, less glamorous pressure point is emerging from the memory chip segment that now accounts for a sizable chunk of the fund’s holdings. Nine US industry associations wrote to Treasury Secretary Scott Bessent and Commerce Secretary Howard Lutnick on June 3, warning that hyperscale AI data centres are gobbling up an outsized share of global memory capacity, threatening supply for sectors ranging from telecoms and automotive to medical devices and consumer electronics.

Samsung Electronics, with a 7.28% weighting, is the ETF's top single stock, followed by Micron Technology at 5.96% and SK Hynix at 5.33%. Combined, memory makers represent more than 18% of the portfolio. That concentration means any reassessment of memory pricing power, capacity bottlenecks, or regulatory intervention could move the needle disproportionately for the fund — far more than for a broad global index.

The ETF’s sector tilt magnifies that sensitivity. Information technology accounts for 71.77% of assets, communication services 14.09%, and consumer discretionary 8.84%. It is anything but a pure software play; instead, the vehicle offers exposure to the entire AI hardware stack, from chip designers to data centre equipment makers.

Attention now shifts to macro catalysts. The US Labor Department releases May consumer price data on Wednesday, June 10 at 2:30 p.m. CET. The April reading came in at 3.8% year on year, well above the Federal Reserve’s 2% target. A hot print could raise the stakes for the Fed’s June 16–17 meeting — the first chaired by Kevin Warsh. According to the CME FedWatch tool, markets assign a 97% probability that the central bank will hold rates steady. But Warsh could signal that further tightening is on the table if inflation proves sticky. EY-Parthenon economist Gregory Daco sees that as a plausible scenario. Higher rates tend to compress valuations for capital-intensive AI infrastructure names, making every line of the policy statement critical for the ETF.

The corporate calendar offers no respite. Samsung is set to present at the Bank of America Korea Conference on June 17 and again at CLSA’s Northeast Asia Forum on June 23. Its commentary on demand trends for high-bandwidth memory chips can sway the stock directly. Then, on June 24 — Nvidia’s annual general meeting and Micron’s quarterly earnings collide. Micron’s guidance has historically moved the entire semiconductor sector.

Technically, the ETF sits about 10% below its all-time high of €222.05, reached on June 2. The 50-day moving average at €177.54 offers a first line of support roughly 12% below the current level. The relative strength index of 53 is neutral, indicating neither oversold nor overheated conditions. However, the 30-day annualised volatility of 34.61% signals that sharp swings are likely to continue.

Over the past 12 months the fund has gained 51.89%, and year-to-date it remains up 28.63%. The recent pullback, while severe, has not broken the prevailing uptrend. But the next two weeks will test whether the market reads the memory supply crunch as confirmation of robust AI investment or as a sign of emerging frictions in cost, capacity, and regulation. For a fund that lives at the intersection of semiconductor manufacturing and data centre buildout, the answer will determine the direction.
