Chip Sector's Recovery Masks a Deeper Shift in Market Dynamics

Chip companies hit record 48% of S&P 500 earnings growth; VanEck ETF jumps 6.43% amid memory-stock rally and AI model shakeout.

The semiconductor industry has reached an inflection point that extends well beyond the daily price swings of exchange-traded funds. Data from The Kobeissi Letter shows that chip companies contributed a record 48 percent of total S&P 500 earnings growth in the second quarter, up sharply from 31 percent in the first three months of the year. This isn't merely a cyclical uptick — it reflects a structural transformation where hardware, not just software platforms, is driving corporate profits.

The VanEck Semiconductor UCITS ETF, which tracks this evolving landscape, closed at €97.98 on July 21 after surging 6.43 percent in a single session. That bounce interrupted a brutal stretch that had left the fund 11.87 percent below its 52-week high of €111.18 from June. Over the trailing 30 days, the ETF still shows a decline of 11.11 percent, underscoring just how violent the sector's swings have become.

Memory-Chip Giants Ignite the Rally

Tuesday's rebound was powered by a broad wave of buying in US memory-chip stocks. Micron Technology, the fund's largest holding at 14.33 percent, jumped roughly 12 to 13 percent after Bank of America upgraded the stock to Buy with a $1,550 price target. The bank cited rising memory demand from new open-source AI models and anticipated share buybacks starting in December 2026 under the CHIPS Act. Western Digital also surged 12.5 percent to $548.39 after reporting third-quarter earnings per share of $2.72, beating the consensus estimate of $2.39, and raising its quarterly dividend to $0.15. Analysts at JPMorgan and Morgan Stanley subsequently set price targets at $650, while BofA went to $732.

The ripple effects extended across Asia. SK Hynix, trading as an ADR, climbed more than 13 percent, while South Korea's Kospi jumped 5.36 percent to 7,164 points on July 22. Japan's Nikkei added 1.95 percent to 67,524 points. The Philadelphia Semiconductor Index gained roughly 5.5 percent on the day.

The Kimi K3 Shock That Preceded the Bounce

The rally came after a tumultuous period triggered by China's Moonshot AI and its Kimi K3 model. Released in mid-July with 2.8 trillion parameters, the model reportedly outperforms established US counterparts in benchmarks while operating at significantly lower cost. That sparked fears that cheaper AI models could render the billions of dollars pouring into data centers and Nvidia chips unnecessary, sending the Philadelphia Semiconductor Index down 10 percent at one point.

The panic eased after Moonshot AI was forced to pause new subscriptions for Kimi K3 on July 19 — its own computing capacity had hit a wall due to overwhelming demand. That detail undercut the narrative that AI-driven chip demand was about to collapse. Still, the episode left investors rattled about the profitability of massive AI infrastructure spending.

Nvidia's Vera Rubin Goes Live

Amid the noise, Nvidia — representing 7.23 percent of the ETF — confirmed on July 21 that full production of its Vera Rubin AI platform had begun. Systems are already shipping to major partners including OpenAI, Microsoft Azure, and Google Cloud. Early cloud provider tests show the new NVL72 racks delivering up to ten times more token throughput per megawatt than the previous generation, a meaningful efficiency gain for energy-constrained data centers.

TSMC Pushes Prices Higher

Taiwan Semiconductor Manufacturing Company, with a 7.51 percent weighting in the fund, is reportedly negotiating price increases of up to 10 percent for 2027. The hikes apply to both advanced and mature manufacturing nodes and are intended to cover rising material costs and the expense of building new fabrication plants. For delayed large orders, surcharges could reach 10 to 15 percent — a sign that demand remains robust despite the debate over AI profitability.

Analyst Sentiment Holds Up

Despite the volatility, industry-wide data remains constructive. The World Semiconductor Trade Statistics organization projects 2026 global semiconductor revenue of roughly $1.51 trillion, a 90 percent increase from 2025, driven by an expected 250 percent surge in memory chips. At Intel, Morgan Stanley analyst Joseph Moore anticipates strong server results ahead of quarterly earnings, forecasting 48 percent revenue growth in the data center business for the second quarter. He raised his price target to $75 from $73 while maintaining a Hold rating.

The VanEck Semiconductor UCITS ETF, which physically replicates the MVIS US Listed Semiconductor 10% Capped ESG Index, charges a total expense ratio of 0.35 percent. The index caps individual holdings at 10 percent to limit concentration, though the top ten positions still account for nearly 80 percent of assets. Besides Micron and Nvidia, the major holdings include Advanced Micro Devices at 12.23 percent, Broadcom at 8.33 percent, and Intel at 8.02 percent.

Technically, the fund has stabilized. The 14-day relative strength index sits at 50.5, a neutral reading that indicates the oversold conditions from early July have cleared. Annualized volatility remains elevated at 57.93 percent, but the consolidation around the €98 level suggests the market is looking past the recent correction and focusing on the sector's underlying earnings power.
