Core Viewpoint - The article introduces a "Fish and Human" analysis method to evaluate investment opportunities based on market participants and profit opportunities, categorized into four quadrants [1]. Group 1: Human and Fish Analysis - The number of participants (humans) indicates market engagement, while the number of profit opportunities (fish) reflects potential gains. Metrics such as trading volume, online discussions, and news heat can be used to assess these factors [1]. - The analysis emphasizes that the assessment of participants and opportunities should be objective and independent of personal circumstances [1]. Group 2: Quadrant Summaries - **Many Humans, Many Fish**: High market interest and numerous profit opportunities, but also intense competition. Investors should leverage unique advantages to succeed in this environment [2]. - **Many Humans, Few Fish**: Overhyped market with high valuations and reduced profit opportunities. Investors need strong risk management skills and should seek undervalued assets or operational opportunities [3]. - **Few Humans, Few Fish**: Low market participation and limited opportunities. Investors should assess the potential for future opportunities and may need to wait patiently for market conditions to improve [4]. - **Few Humans, Many Fish**: Abundant investment opportunities with low valuations but low market attention. This quadrant is ideal for finding hidden gems before they attract more investors [5].
