Group 2: Stock Selection Challenges - Three methods of stock selection are discussed: technical trading, value investing, and copying successful investors, with each method presenting significant challenges [8][28]. - Technical trading is discouraged as it is likened to giving money to quantitative funds that operate with high speed and accuracy [9][10]. - Value investing requires deep understanding of companies, which is difficult for most ordinary investors due to a lack of experience and time [12][20]. - Copying the trades of successful investors can lead to poor outcomes due to information lag and lack of understanding of the underlying investment logic [24][25].

Group 4: Asset Allocation as a Solution - Asset allocation is proposed as a viable alternative to stock selection and timing, as it leverages the natural relationships between different asset classes [36][39]. - By diversifying investments across various asset classes, investors can achieve internal hedging, allowing for stable returns regardless of market conditions [41][44]. - The article highlights that asset allocation does not require precise market timing, making it a more accessible strategy for ordinary investors [46][52]. - Rebalancing strategies can further enhance returns by allowing investors to sell high-performing assets and buy underperforming ones, thus smoothing out the investment curve [55][58].
