Semiconductor Sectors Undergo Sharp Mid-July Correction Amid AI Position Unwinding, Earnings Verification Set to Drive Stock Differentiation

Global semiconductor equities have faced sharp market readjustment through July, as crowded trading positions across AI hardware segments began to unwind. Market sentiment shifted further following news of Meta’s plans to lease out its idle computing capacity, stoking investor doubts over long-term returns on massive AI capital expenditure. Memory chips and semiconductor equipment, two sub-sectors that had recorded steep gains earlier in the year, moved lower in tandem on A-share markets.

Industry analysts frame the pullback as a short-term technical correction after excessive speculative positioning, rather than a structural reversal of fundamental industrial momentum. As the half-year earnings reporting window opens, investor focus across semiconductor stocks is shifting away from thematic speculation towards tangible profit delivery, with leading specialised manufacturers capable of consistent earnings growth set to stabilise share prices first.

Confluence of Factors Trigger Cross-Market Sector Pullback

Technology equity markets worldwide have seen pronounced volatility in recent trading sessions. Wind data records a cumulative fall of more than 11 per cent on the PHLX Semiconductor Sector Index (SOX) from the start of July through 9 July Beijing time. On mainland China’s A-share market, the Wind Semiconductor Index traded choppily across the month, yet closed 8.55 per cent higher on 9 July. Multiple constituent securities hit the 20 per cent daily upward limit, including Aisen Co., Ltd and Shanghai Hecrystal Co., Ltd. Changchuan Technology and Yongsi Electronics climbed more than 17 per cent, while Moore Threads-U and SMIC advanced over 13 per cent. Other large-cap semiconductor names such as MLS, Huatian Technology, Tongfu Microelectronics, JCET and GigaDevice closed trading at their daily upper limits.

Market circulating reports reveal Meta’s proposed external leasing of surplus AI computing infrastructure, alongside preparations to roll out proprietary cloud services. This narrative shift has rapidly altered investor sentiment, replacing prior optimism centred on persistent compute shortages with concerns over oversupply in data centre hardware. Internal market dynamics also fuelled the downward move, with substantial profit-taking pressure building after the sector’s months-long rally. Samsung Electronics released preliminary Q2 results that doubled quarterly revenue and delivered an eighteenfold jump in operating profit, yet the published metrics fell short of the aggressive earnings expectations priced into shares by investors, prompting broad profit realisation across global chip stocks.

Semiconductors had stood among the most heavily traded sectors on A-shares before the market reset. Wind statistics show the Wind Semiconductor Index had rallied 105.06 per cent since the start of 2026 up to 30 June.

Fund management houses including Guolian An Fund identify thinning positioning density within AI hardware as the core catalyst for the sell-off. Excessively bullish sentiment surrounding AI-related stocks triggered coordinated risk reduction by institutional capital, with AI-exposed chip firms bearing the brunt of liquidation. Risk aversion spilled over from overseas bourses to domestic Chinese equities, depressing market risk appetite onshore, while correlated downward moves across global markets amplified the short-term sector drawdown.

Price Hikes and Sustained End-User Demand Underpin Solid Industrial Fundamentals

Volatile share price performance stands apart from robust underlying operating conditions across the semiconductor value chain. According to Xinhua Finance, preliminary figures published by South Korea’s Ministry of Trade, Industry and Energy on 1 July show national exports surged 70.9 per cent year-on-year in June to a record USD 102.25 billion, marking the fastest monthly growth rate since October 1978. After adjusting for working-day discrepancies, export growth stood at 59.5 per cent, confirming material improvement in external global demand.

Semiconductors acted as the primary engine of this export expansion, with June chip shipments hitting USD 44.82 billion to set a new all-time monthly record, driven by robust investment inflows targeting artificial intelligence and data centre infrastructure. Imports expanded 30.1 per cent to USD 66.10 billion, lifting the monthly trade surplus to USD 36.15 billion, the first print above the USD 300 billion threshold. South Korea’s position as a bellwether for global semiconductor trade means two consecutive months of double-digit export expansion signals strong end-market demand permeating every tier of the international chip supply chain.

Against this backdrop of persistent consumption growth, nearly twenty global analogue and power semiconductor manufacturers rolled out coordinated price rises on 1 July. International vendors Infineon and Texas Instruments, paired with domestic players Silan Microelectronics and Yangjie Technology, lifted product pricing across ranges by between 5 and 25 per cent, marking the second round of industry-wide tiered price increases in 2026.

Market analysts attribute the widespread cost uplift primarily to surging downstream demand, constrained component supply and pass-through inflation from higher raw material costs, with AI-focused chip variants recording the steepest mark-ups. Cost inflation within analogue and power semiconductors is propagating upstream to semiconductor equipment and electronic materials businesses, spreading cyclical prosperity throughout the full industrial chain.

Half-Year Earnings Releases to Define Subsequent Sector Performance

Following the earlier extended rally and recent rapid price retracement, forward semiconductor stock performance sits at the centre of institutional investor focus. Brokerage sector analysts uniformly recognise AI-related consumption as the core driver of industrial expansion through the second half of 2026, while investment frameworks shift from pricing uplift speculation towards confirmed earnings certainty.

Sector analysts at Dongguan Securities outline artificial intelligence as the dominant investment theme for the remainder of the calendar year, advising portfolio allocation around two core growth vectors: high-demand sub-sectors and rising domestic substitution penetration. Ongoing scaling of AI training, inference and autonomous agent applications continues to lift capital expenditure budgets for overseas cloud operators, sustaining heavy investment in compute infrastructure and generating steady order inflows for memory chips, central processing units, power semiconductors and semiconductor materials. The research team flags memory storage, advanced packaging and semiconductor manufacturing equipment as priority segments where robust market demand aligns with accelerating localised supply chain development.

The publication of interim financial previews reinforces this fundamental investment logic, with multiple A-share semiconductor manufacturers translating industrial expansion into tangible bottom-line growth. Jiangbolong forecasts half-year operating revenue ranging from RMB 22 billion to RMB 25 billion, alongside net profit of RMB 9.2 billion to RMB 11 billion, representing a year-on-year jump of between 62,204.03 and 74,393.95 per cent. Changchuan Technology, a leading supplier of semiconductor testing gear, expects half-year net profit to land between RMB 900 million and RMB 1 billion, an annual rise of 110.76 to 134.18 per cent.

The chief electronics industry analyst at China Galaxy Securities notes the completion of the second coordinated price hike by global analogue chip producers, with AI and automotive analogue components leading the uplift. Full utilisation of eight-inch wafer fabrication capacity creates scope for a third round of price adjustments in the second half, and the current demand-driven pricing cycle carries greater momentum than the 2021 upturn, supporting further cyclical expansion across analogue and power semiconductor segments. Uniform price revisions from wafer foundries maintain tight supply chains powered by AI spending, opening room for upward earnings guidance and valuation recovery across listed chip stocks.

Within equipment manufacturing, ASML has raised its full-year revenue outlook, while Samsung and SK Group have pledged combined domestic investment exceeding 4,800 trillion South Korean won to expand AI data centre assets and semiconductor supply chain capacity. Global capital expenditure for artificial intelligence infrastructure remains in an expansionary cycle, sustaining robust order volumes for semiconductor production equipment, with faster progress in domestic substitution for manufacturing hardware and components recorded in Q2. Raw material pricing is bolstered by helium cost inflation and elevated fab capacity utilisation rates, with climbing material prices set to form a major driver of stronger half-year operating profits for upstream material suppliers.
