A-shares staged a V-shaped recovery on August 14, with the Shanghai Composite Index closing up 0.33% at 3,927.18 points. Technology stocks experienced wide intraday swings, while the ChiNext Index rose 1.12% after an initial decline and subsequent rebound. Total market turnover reached 2.16 trillion yuan, a significant decrease from the previous trading day.
Sector-wise, the ChiNext artificial intelligence (AI) sector led the gains, with optical module leaders like Eoptolink Technology Inc. Ltd and Tianfu Communication Technology Co., Ltd. rising over 4%, and Zhongji Innolight Co., Ltd. gaining over 2%. The ChiNext AI ETF, which heavily weights these optical module leaders, closed up 3.04%. The strong performance of the optical module sector is underpinned by two key drivers: first, in a tight computing power supply environment, demand for optical modules shows the highest certainty; second, a shift toward cloud-based computing leasing combined with increased domestic capital expenditure is creating a synergy of domestic and international demand.
Computing power leasing stocks surged again, with Atlas (Shanghai) Data Center Co., Ltd. hitting the daily limit and Wangsu Science & Technology Co., Ltd. achieving a 20% gain. The Cloud Computing ETF closed up 1.95%, reaching a new all-time high. DeepSeek announced a significant price hike starting August 17, which could lead to a revaluation of domestic computing power, with the upstream computing leasing sector likely to benefit the most. The non-ferrous metals sector edged higher, with the largest and most liquid Non-ferrous Metals ETF closing up 1.14%, attracting net subscriptions of 31.2 million shares after receiving 10 million yuan in inflows the previous day. Analysts suggest that both the macroeconomic environment and corporate earnings support a transition of the non-ferrous metals market from a rebound to a sustained uptrend, offering high allocation value at current levels.
The previously hot innovative drug and contract research organization (CRO) sectors, which had been on a five-day winning streak, saw a pullback. The Medical ETF, with over 30% CRO exposure, fell 1.13%, while the Innovative Drug ETF declined 1%. However, both ETFs traded at a premium, indicating active buying support. Industrial Securities noted that as the mid-report season approaches, several innovative drug and CRO leaders have reported earnings that exceeded expectations, reaffirming the industry's positive upward trajectory.
Key Market Points for the Week and Core Themes
For the week, the Shanghai Composite Index fell 0.33%, the Shenzhen Component Index rose 0.3%, and the ChiNext Index gained 1.77%. Market analysts believe the market has entered a phase of declining volatility and bottom-building. The earnings season in August will be a critical catalyst for the main market themes, with core technology sectors expected to deliver results, potentially driving a re-rating cycle based on earnings and valuation. If hard tech stocks stage a recovery, the most certain sectors include optical module leaders and domestic computing power, while other positive themes like innovative drugs also deserve attention.
In-Depth Analysis: AI, Cloud Computing, and Non-Ferrous Metals
The ChiNext AI sector led the market, with optical modules and computing leasing showing strong activity. The ChiNext AI ETF (159363) closed up 3.04%, with fund flows turning positive, netting 10 million shares. The weekly chart shows a continued recovery, marking consecutive weekly gains. Recent earnings calls from global tech giants like Coherent, Lumentum, CoreWeave, Nebius, and Chinese internet giant Tencent have provided new narratives for the AI industry, supporting the global AI sector's recovery. Key takeaways from these calls include: Coherent reported extremely high demand visibility, faster-than-expected CPO/NPO progress, and doubled indium phosphide capacity; Lumentum noted strong 1.6T demand, improved CPO visibility, and new increments from NPO; CoreWeave highlighted a supply-demand imbalance with price increases, expansion into AI inference, and customer diversification; Nebius saw strong leasing demand, improving ROI, and rising prices; and Tencent continued to accelerate capital expenditure, with AI-to-B showing monetization potential.
The logic for investing in optical modules is clear. First, in a tight computing power environment, demand for optical modules is the most certain. Customers are signing long-term agreements (LTAs) that provide clear guidance on volume and price, significantly improving long-term visibility. Demand for next-generation products like 1.6T is exceeding expectations, and advanced technologies like CPO/NPO are accelerating, creating definite growth opportunities. Second, the transformation of computing leasing to cloud services, combined with rising domestic capital expenditure, creates a dual demand driver. Computing leasing companies are evolving into new cloud providers, with AI inference becoming a new demand driver. Each infrastructure expansion directly translates into procurement for high-speed optical modules. Domestically, internet giants like Tencent are accelerating capex, and the AI-to-B monetization path is being validated. Domestic optical module leaders are benefiting from both incremental domestic orders and strong international demand from cloud and leasing giants.
Computing Power Price Hike Signals Major Shift
The computing power sector saw a surprise surge in the afternoon. The Cloud Computing ETF (159099) rose 1.95%, closing at a new high. Since August, the computing leasing concept has steadily strengthened, up 14.59% by the close on August 14, significantly outperforming tech indices like the ChiNext and STAR 50. Strong performance and stock price surges of international computing leasing giants have had a clear mapping effect on domestic peers. The certainty of a computing power shortage, combined with improved model and application capabilities, is expected to further expand demand. The ETF's underlying index has a 58.95% weighting in computing leasing, leading comparable indices. The news of DeepSeek's price hike, using a peak-valley pricing model, marks a shift from price wars to sustainable profitability and confirms the tight supply of computing power. The price hike moves profits upstream, with computing leasing likely being the most direct beneficiary. Additionally, Shanghai released a policy supporting private enterprises in renting computing resources for AI model training. According to the China Academy of Information and Communications Technology (CAICT), the domestic computing leasing market is expected to exceed 260 billion yuan by 2026, potentially reaching one trillion yuan by 2030 with a compound annual growth rate of over 43% for smart computing. Northeast Securities noted that the AI industry is entering a phase of large-scale commercialization, with model iteration and diverse scenarios driving demand. Top internet companies are locking in long-term smart computing contracts, confirming the supply shortage. Small and medium-sized AI entities face barriers to building their own clusters, broadening the demand base for leasing. As token usage scales exponentially, the industry's business model is shifting from charging by card or time to a more refined per-token model. Combined with tightening supply of high-end GPUs and supportive domestic policies, the sector is poised for both volume and price growth.
Non-Ferrous Metals Sector Attracts Major Inflows
The non-ferrous metals sector followed the market's V-shaped recovery, with over 61 billion yuan in net main capital inflows, ranking third among 31 Shenwan primary industries. The largest and most liquid Non-ferrous Metals ETF (159876) rose 1.14%, with a daily turnover of 91.85 million yuan, up 24% from the previous day. The sector attracted strong fund inflows, with net subscriptions of 31.2 million shares on the day, following 10.64 million yuan in inflows the previous day. Over the past 20 trading days, the ETF has accumulated 124 million yuan in net inflows. Rare earth leaders led the gains, with China Rare Earth Resources and Technology Co., Ltd. hitting the daily limit, and Zhongse Rare Earth Co., Ltd., Shenghe Resources Holding Co., Ltd., and China Northern Rare Earth (Group) High-Tech Co., Ltd. rising over 4%. The rally was supported by improved macro liquidity and a positive industry outlook. The U.S. July CPI and PPI data showed easing inflation, leading traders to further reduce expectations for a rate hike in September. CICC suggested that easing inflation, cooling employment data, and a dovish Fed pivot could lead to further global liquidity easing in the second half of 2026, benefiting non-ferrous metals. In the rare earth sector, a "low volume, high price" pattern is evident. China's rare earth exports in the first seven months of the year fell 10% year-on-year to 34,706.3 tons, while the average export price doubled. SMM data shows that all 10 rare earth companies that have disclosed interim reports or forecasts reported year-on-year profit growth. Guosheng Securities noted that permanent magnets, the largest downstream application for rare earths, are driven by demand from new energy vehicles and humanoid robots. CICC believes that the peak season for downstream products like automobiles and industrial robots in the second half of the year could boost raw material procurement, supporting rare earth prices. BOC International pointed out that the macro environment and corporate earnings support a transition of the non-ferrous metals sector from rebound to reversal, and if the broader market enters a recovery phase, the high-beta sector could outperform.
