和讯研究员靳文云:浅谈投资风格
He Xun Cai Jing· 2025-07-10 08:40
Core Viewpoint - The article discusses two primary investment styles: trading-oriented and value-oriented, highlighting their characteristics and the challenges associated with each style [1][2][3]. Trading-Oriented Investment Style - Trading-oriented investors engage in frequent transactions, aiming to profit from short-term market movements by capitalizing on hot topics and investor sentiment [1]. - This style often involves speculative trading in small-cap stocks and leveraging market trends to drive quick gains [1]. Value-Oriented Investment Style - Value-oriented investors focus on selecting high-growth companies or stable dividend-paying stocks, holding them for the long term to benefit from their growth [2]. - The article emphasizes that while high-growth industries like AI and biotechnology present opportunities, they also come with significant challenges, including market volatility and competition among leading companies [2][3]. Investor Characteristics - Patience and determination are crucial for value investors, as they must endure market fluctuations and uncertainty while waiting for their investments to appreciate [3]. - The article notes that few investors possess the commitment to maintain a value investment strategy, but those who do can achieve substantial returns when their investments reach their true value [3].

巴菲特说不懂不投,达里奥做分散配置,两者有矛盾吗?

Core Viewpoint - The article discusses two prominent investment philosophies: Warren Buffett's focus on understanding one's own capability circle and Ray Dalio's all-weather diversified allocation strategy, questioning which approach is more beneficial for investors [1][2][3]. Group 1: Investment Philosophy - Buffett's principle of "do not invest in what you do not understand" is widely recognized, yet many investors confuse familiarity with true understanding [3][5]. - Dalio's strategy emphasizes diversification, but investors often fall into the trap of diversifying without understanding the underlying correlations, leading to ineffective risk management [5][11]. Group 2: Understanding Risk - True understanding in investing does not equate to predicting price movements; it involves comprehending potential losses and their probabilities [6][9]. - The article highlights that overconfidence stemming from cognitive biases can be more detrimental than a lack of knowledge [8][17]. Group 3: Data Insights - Historical data from 2005 to 2025 indicates that a stock-bond allocation reduces maximum drawdown by 15% compared to a pure A-share investment [16]. - Further diversification into global assets, including U.S. stocks and gold, minimizes drawdown while maintaining returns, validating both Buffett's and Dalio's investment principles [16][17]. Group 4: Bridging Understanding and Diversification - The article suggests that a balanced approach can be achieved by integrating Buffett's focus on understanding with Dalio's diversification, allowing for a more robust risk-return profile [17].

嫦娥六号玄武岩样品最新研究:破解月球内部异常“贫瘠”之谜
Huan Qiu Wang Zi Xun· 2025-07-10 04:32
来源:中国新闻网 中新网北京7月10日电 (记者 孙自法)中国科学家对嫦娥六号采自月球背面南极-艾特肯盆地(SPA)的28亿 年前的玄武岩样品进行研究,最新又取得一项重大科学成果——揭示月球背面月幔物质的"超亏损"(通 俗而言即异常"贫瘠")特征,并提出其成因的两种可能模型,从而为全面了解月球早期的壳-幔演化历史 提供了关键信息。 这项破解月球内部异常"贫瘠"之谜的成果论文,由中国科学院国家天文台联合中国科学院地质与地球物 理研究所、中国地质大学(北京)、北京高压科学研究中心、东华理工大学等多家科研院校的研究团队共 同完成,并同嫦娥六号月背样品的另三项科研成果一起,于北京时间7月9日夜间以封面文章形式在国际 知名学术期刊《自然》上线发表。 "一扇窗口" 研究团队介绍说,月球的正面和背面差异巨大,正面相对平坦,有广阔的玄武岩平原;背面则高地遍 布,月海稀少。科学家提出了很多理论来解释月球的这种"二分性"特征,包括月球形成早期岩浆洋冷却 结晶不均匀、月幔内部物质对流不对称、正背面巨型撞击作用的差异等。然而,过去所有的月球采样任 务都只在月球正面进行,月球背面样本的缺失使得背面深部月幔特征一直是未解之谜。 "后天改 ...
