Group 1 - The core issue in the domestic GPU industry is that institutions regret selling their shares early, missing out on significant profits, with losses exceeding 8 billion yuan collectively [1][3]. - The case of Moer Thread is highlighted, where an institution sold 837,734 shares for 50 million yuan before the IPO, only to see the shares soar to a market value of 567 million yuan on the first trading day, resulting in a missed profit of 517 million yuan [2][3]. - Another leading GPU company, Muxi Co., also experienced a similar situation, where shares sold for 50 million yuan appreciated to over 300 million yuan on the first trading day [3]. Group 2 - The reasons for institutions selling early mirror those of retail investors, often due to a lack of confidence in the industry outlook or the need to liquidate investments, indicating a failure to understand the underlying trading behaviors [4][14]. - The current bull market in 2025 has seen a 20% index increase, but only 40% of stocks outperformed the index, suggesting that many investors missed opportunities not due to poor stock selection but due to misunderstanding market dynamics [4][15]. - Understanding trading behavior through data analysis can help investors avoid premature selling and identify genuine market movements, as institutions often engage in tactics like "shaking out" weaker hands to accumulate shares at lower prices [14][15].
