法国记者的提问,给老黄整不会了,被硬控3秒钟,憋出一句「that's a strange question」……
继续看罗伯茨一派的判词,提到了一个重要的宪法原则:重大问题原则,Major Questions Doctrine,简称 MQD,意思是当政府行政分支做出重大影响的决策时,不能依靠模糊的法律文本的空间,而应该明确获得国会授权,最高法院停止拜登政府取消学生贷款计划也是基于这一原则。 多数派法官对于司法主张的“特权例外论”:由于涉及关税的政策属于外交事务与国家安全的范畴,认为国家处于“紧急状态”之下,川普应当享有最高程度的司法特权的说法表示彻底反对,认为「重大问题原则」不应在此适用 。  罗伯茨对此进行了无情的驳斥:重大问题原则不存在任何所谓的“紧急状态法案特例”,尽管关税无疑会深度牵涉外交事务,但这绝对不能改变一个宪法事实:制宪先驱们刻意强调了将和平时期施加关税的权力“完全且排他性地”赋予了🇺🇸国会 ,多数意见总结道,外交事务的背景绝不能成为颠覆宪法分权架构的借口,当川普试图在未获国会明确授权的情况下篡夺国会核心职能时,「重大问题原则」不仅适用,而且必须予以最为严格的司法审查

和Quant Alex @StochAlex07 讨论: SABR Theta与Spot Theta+Vol Theta+Cross Theta的异同与应用,以及SABR模型自洽性分析。 **English Summary of the Chat** **SABR Theta vs Spot Theta + Vol Theta + Cross Theta** The conversation between **Alex Wu** (white bubbles) and **Jeff Liang** (green bubbles) is a technical discussion focused on **SABR Theta versus Total Theta** (i.e., Spot Theta + Cross Theta + Vol Theta), model self-consistency, PDE residual, and the correct definition of SABR Greeks. ### Key Points Discussed: 1. **SABR Gamma = Spot Gamma** (first major question, raised by Jeff) Jeff asked whether SABR Gamma (\(\partial^2 P / \partial F^2\)) is identical to Spot Gamma and whether it includes the dependence of \(\sigma_B\) on \(F\). He also provided the full chain-rule expansion of SABR Gamma in terms of Black-76 Greeks. Alex confirmed the understanding and **later affirmed in code** that this is exactly how SABR Gamma is implemented in their system. 2. **SABR Theta vs Total Theta and Model Self-Consistency** (main topic, led by Jeff) Jeff shared a clear 3-point understanding: - SABR Theta is computed directly via the SABR approximation formula to obtain \(\sigma_B\), then applying the Black-76 chain rule: \(\partial P/\partial t =\) BS_Theta(\(\sigma_B\)) + BS_Vega \(\cdot \partial\sigma_B/\partial t\). - Total Theta is the exact decomposition from the SABR PDE (Spot Theta + Cross Theta + Vol Theta). - When the model is **fully self-consistent** (Residual = \(\partial P/\partial t + \mathcal{L}P = 0\)), SABR Theta = Total Theta; otherwise the difference is the unexplained PnL caused by the approximation error in the Hagan formula (especially pronounced in long-dated, high vol-of-vol, or high-skew options). 3. **Practical Implication – Theta Decomposition Decision** (comment by Alex) Alex noted that whether to perform Theta decomposition depends on the risk-management approach: - Without decomposition → use SABR Gamma vs. dP/dt. - With decomposition → SABR Gamma maps to Spot Theta, Vanna to Cross Theta, and Volga to Vol Theta. **Overall Tone**: The discussion is highly technical and collaborative. Jeff drives the conversation by asking clarifying questions and presenting a well-structured 3-point summary of his recent study. Alex provides confirmations, practical insights, and code-level validation. Both participants demonstrate a strong command of SABR model nuances, particularly the relationship between approximation error, PDE residual, and real-world risk management.

# Role: Pattern Breaker / 思想颠覆者 ## Profile 你是由 Mike Maples Jr. 与 Peter Ziebelman 思想武装的顶级风投家与战略顾问。你极度厌恶平庸的“更好”,只寻找根本性的“不同”。你的眼中没有“市场份额”,只有“范式转移”。 ## Core Philosophy (The Lens) 你依据以下核心逻辑审视一切: 1. **Pattern Breaking (颠覆范式) > Pattern Matching (匹配范式)**:拒绝增量改进,寻找规则的重写。 2. **Inflection Theory (拐点理论)**:机会 = 外部根本性变革 (Inflection) + 非共识的洞见 (Insight)。 3. **Living in the Future (活在未来)**:不在当下寻找痛点,而在未来创造缺失。 4. **Movement (运动)**:不卖产品,只发起一场关于未来的运动。 ## The Interaction Ritual (The 4-Step Test) 当用户提供一个创业想法或商业计划时,不要给出常规建议,必须进行以下残酷的“压力测试”: ### Step 1: 寻找“浪潮” (The Inflection Check) * **Question**: "你的想法是基于什么根本性的外部技术或社会变革(拐点)?为什么是现在?(Why Now?)" * *Critique*: 如果用户说的是“市场很大”或“团队很强”,请无情反驳。寻找像“GPS芯片之于Uber”那样具体的外部赋能因素。 ### Step 2: 寻找“非共识” (The Consensus Trap) * **Question**: "你的核心洞见是什么?如果不告诉别人,大多数理性的聪明人会同意你的观点吗?" * *Critique*: 如果大多数人认为这是个好主意,警告用户这可能是个陷阱(红海)。寻找那些听起来“愚蠢”或“不可能”,但基于拐点逻辑却是必然发生的洞见。 ### Step 3: 寻找“不同” (Different vs. Better) * **Question**: "你是在做‘更好的苹果’,还是‘第一根香蕉’?" * *Critique*: 识别用户是否在与现有巨头进行比较(陷入比较陷阱)。迫使他们定义一个新的品类,在这个品类里,他们是唯一的选择。 ### Step 4: 寻找“运动” (The Movement) * **Question**: "你打算如何重新定义现状(Status Quo)为‘敌人’?你的早期信徒是为了什么信念而加入你?" * *Critique*: 检查是否有能够引发情感共鸣的叙事(Storytelling)。 ## Tone * 直率、甚至略带“不合群 (Disagreeable)”的挑剔。 * 使用《Pattern Breakers》中的隐喻(如“海鸥乔纳森”、“爵士乐队”、“看不见的大猩猩”)。 * 不要为了礼貌而妥协真理。 ## Start 请问我:“请告诉我你那个可能被世人认为是‘愚蠢’,但你坚信能改变未来的想法。”

无法合成等bug现已紧急修复,感谢您的耐心等待。 Bug出现原因归结为bnbchain无原生像素nft及rpc节点网络卡顿导致。 NFT的mint资金届时将全部添加为代币 $渣 的池子。 为防止狙击手抽取流动性,用作池子的添加资金已做混淆处理,此举在于保护所有blonks持有者的权益。否则将会被狙击手抽走持有者的大部分利益。 代币部署时间在24h之内,我们希望吸取足够的经验,从而充足的完成此次部署,确保每一位Blonks的持有者都获得利益,请您耐心等待。 有任何确凿的疑问,请在下方提出。 Blonks! —— The bugs preventing synthesis and similar issues have now been urgently fixed. Thank you for your patience. The cause of the bug was due to BNB Chain lacking native support for pixel NFTs, combined with RPC node network congestion. All funds from the NFT mint will be fully added to the liquidity pool for the $渣 token. To prevent snipers from extracting liquidity, the funds being added to the pool have been obfuscated. This measure is intended to protect the interests of all Blonks holders. Otherwise, snipers would drain away the majority of the holders’ benefits. The token will be deployed within the next 24 hours. We hope to draw on sufficient experience to ensure this deployment is completed thoroughly, guaranteeing that every Blonks holder benefits. Please be patient. If you have any specific questions, please ask them below. Blonks!
