在牛市里反思：大多数人的亏钱，其实输在路径依赖

Core Viewpoint - The article emphasizes the importance of flexible asset allocation over specialization in a single investment area, particularly in the context of the A-share market, where market conditions can change rapidly [5][9][10]. Group 1: Investment Strategy Evolution - The investment strategy has evolved from focusing solely on A-share funds to diversifying into US ETFs and global markets, indicating a shift towards a more comprehensive asset allocation approach [4][5]. - The current asset allocation structure is described as "all-weather," combining stocks, bonds, and commodities to enhance returns while minimizing volatility and risk [5][10]. Group 2: Path Dependency and Its Risks - Path dependency is identified as a detrimental mindset that can hinder investors' ability to achieve stable returns, with examples from real estate and A-shares illustrating the consequences of this approach [6][7][11]. - The article argues that many investors mistakenly believe that specialization will lead to success, while in reality, a broader framework is necessary to avoid costly mistakes [9][10]. Group 3: Asset Allocation Framework - A scientific asset allocation framework is essential for improving error tolerance, as most investors cannot specialize in a single asset class [10][12]. - The framework should include specific allocations for stocks, bonds, and commodities, and investors should adhere to these rules unless significant issues arise [10][15]. Group 4: Practical Implementation - The article suggests using a three-part method for asset allocation, starting with a risk preference test to determine the appropriate balance between aggressive and conservative investments [13][15]. - Investors are encouraged to take a gradual approach to investing, allowing time to build knowledge and avoid overcommitting based on a false sense of expertise [14][15].
