Group 1 - The semiconductor ETFs experienced significant gains, with the chip leader ETF rising by 5% and the semiconductor equipment ETF soaring by 8% due to rumors about a domestically developed EUV lithography machine expected to enter trial production in Q3 2025 and achieve mass production in 2026 [1] - The current PE valuation of the chip index has reached 143 times, placing it in the 99th percentile, the highest level since the index's inception, even surpassing the peak in 2021 [2][4] - The PB valuation of the chip index stands at 7.46 times, which is in the 83.71 percentile, indicating that while it is not as high as the PE valuation, it is still at a historically elevated level [4] Group 2 - Despite the high valuations, many investors remain cautious due to past experiences with high-valuation sectors like liquor, healthcare, and new energy, where significant losses were incurred despite stable profit growth [6][9] - Companies like Kweichow Moutai and CATL have seen their PE valuations drop significantly, with Moutai's PE decreasing from 70 times to 20 times, while CATL's dropped from 160 times to 29 times, highlighting the impact of valuation on stock performance [8][11] - The trend model strategy is proposed as a solution for navigating high-valuation environments, allowing investors to hold onto stocks as long as they maintain an upward trend, thus avoiding significant losses during market downturns [14][17] Group 3 - Alibaba announced a significant investment of 380 billion in AI infrastructure and a partnership with NVIDIA, leading to a 10% increase in its stock price, although it still needs to rise 40% to reach its previous high [19] - The ongoing investment in new energy by China contrasts with the U.S. approach, which may lead to China dominating the global new energy sector in the future [19]

Core Viewpoint - The article discusses the role of margin financing in driving the current bull market, highlighting the industries that have attracted the most margin funds and their performance compared to the Shanghai Composite Index. Group 1: Margin Financing Dynamics - Margin financing has become a core driver of the current bull market, with high-risk speculative funds ignoring valuations and fundamentals, focusing solely on price trends [1][2]. - A cycle is created where industries with increased margin financing see price rises, leading to further investments and continued price increases, particularly in the A-share market without short-selling mechanisms [2][3]. Group 2: Historical Context and Current Trends - In the 2015 bull market, the top five industries by margin financing were: - Securities: 174.4 billion - Banking: 145.5 billion - Real Estate: 107.2 billion - Construction: 77.3 billion - Non-ferrous Metals: 75.7 billion - These five industries accounted for 26% of the total margin financing of 2.2 trillion [2]. - As of now, the margin balance in the Shanghai and Shenzhen markets has reached 2.2123 trillion, nearing the historical peak of 2.2664 trillion from June 2015 [3].

Group 4: Valuation and Future Outlook - The current bull market has shifted focus from traditional sectors like banking and real estate to high-growth sectors such as communication, chips, AI, and robotics, which are now attracting margin financing [7][13]. - Valuations for these sectors are high, with PE ratios indicating that they are expensive: - Communication ETF: 48x - Integrated Circuit ETF: 197x - AI ETF: 230x - Robotics ETF: 81x [14][19][21]. - The article suggests that while these sectors are currently expensive, the strategy should focus on price trends rather than valuations for future investments [23].

Core Viewpoint - The recent performance of the A-share market has been exceptionally strong, with significant profits from the chip leader ETF grid established in April 2022, achieving a grid return of 53.68% and an absolute return of 70.85% compared to the ETF fund's return of 31.94% during the same period [1][2]. Summary by Relevant Sections Grid Performance - The chip leader ETF grid was established on April 15, 2022, and has since yielded a grid return of 53.68% and an absolute return of 70.85% [2]. - The ETF fund's return during the same period was 31.94%, indicating that the grid strategy significantly outperformed a buy-and-hold approach [1][2]. Market Conditions - The chip industry had already corrected over 30% from its peak, providing a sufficient safety margin for establishing the grid [3]. - Despite initial underestimations of the bear market's severity, the grid strategy has proven successful, allowing for a timely exit [3]. Valuation Metrics - The current price-to-earnings (PE) ratio for the chip index has risen to 126 times, placing it in the 98.78 percentile, the highest since the index's inception [5][6]. - The price-to-book (PB) ratio stands at 13.88 times, also near historical highs, indicating that both PE and PB valuations are at their peak levels [5][6]. Future Outlook - The chip industry is still viewed positively despite high valuations, as it aligns with national strategic needs and is likely to be a key player in the current bull market [8][18]. - For future investments in the chip sector, the focus should shift from valuation metrics to price trends, suggesting that if the price maintains an upward trajectory, it should be held; otherwise, it should be sold [9][18]. Investment Strategy - The grid strategy involves buying more when prices drop and selling when they rise, which is particularly effective in a bull market [11][12]. - The distinction between grid trading and trend trading is emphasized, with the latter being more suitable for high-valuation sectors [18].
