斯皮茨纳格尔不是孤例。对冲基金潘兴广场资本管理(Pershing Square Capital Management)的创始人 比尔·阿克曼(Bill Ackman),在这场灾难中赚得更多。他下注 2600 万美元,最终获得 36 亿美元的收 益,回报达 138 倍。《巴伦周刊》评价说,"这是有史以来最伟大的交易之一"。 这两件事激发了帕特森的兴趣,老记者的敏锐和直觉让他觉得金融投资可能已经出现新的变化。此前, 他捕捉到了量化金融的崛起,写了著作《宽客》(The Quants),里面的人物包括文艺复兴科技的创始 人詹姆斯·西蒙斯(James Simons)等。在另一本书《暗池》(Dark Pools)中,他较早地揭露了高频交 易和 AI 可能给金融市场带来的风险。 经过 3 年的调查研究和采访写作后,帕特森在 2023 年出版著作 Chaos Kings: How Wall Street Traders Make Billions In The New Age Of Crisis。中文版最近推出,书名译为《逆风翻盘:危机时代的亿万赢 家》。书的主角是阿克曼、斯皮茨纳格尔、纳西姆·尼古拉斯·塔勒布(Nassim ...

Core Viewpoint - The article emphasizes the importance of honesty in both personal reflection and investment decisions, suggesting that true understanding and improvement come from acknowledging one's weaknesses and mistakes [3][4][19]. Group 1: Challenges of Honesty - The first challenge of honesty is the reluctance to acknowledge known weaknesses, as many investors avoid admitting their losses, which can hinder their growth [9]. - The second challenge lies in the inability to identify deeper issues, similar to how patients may struggle to articulate their true feelings to a psychologist [9][10]. - Many investors focus on external validation rather than internal reflection, leading to poor decision-making and a lack of accountability [10][13]. Group 2: The Impact of Ego on Investment - Investors often treat the market as a battleground for self-worth, where profits are seen as validation and losses as a threat to their dignity [11][13]. - This ego-driven approach can prevent investors from recognizing their mistakes, leading to further losses as they refuse to accept that their initial decisions were flawed [11][12]. - The article highlights that acknowledging mistakes is not a sign of defeat but rather a crucial step towards recovery and better decision-making [14][16]. Group 3: Learning from Mistakes - The process of admitting errors can lead to valuable insights and improved strategies, as demonstrated by an investor who learned to wait for market corrections after reflecting on past decisions [15][17]. - Recognizing that losses are part of a probabilistic game rather than a personal failure can help investors detach their self-esteem from their financial outcomes [12][18]. - The article suggests that a more honest dialogue with oneself and tools like AI can facilitate this process, allowing investors to focus on the essence of wealth accumulation rather than ego [18][19].
