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.

L站官方 App 终于上架了！ 10 月 2 日上的 App Store，叫 LINUX DO Community，免费，iOS 17 以上就能装。 装上一看，没账号只能围观，发帖回复都不行。 想去网页注册，一打开就被 Cloudflare 拦在门外。 我也卡在这一步。翻到一个办法，原理很简单： 被拦是因为代理节点的 IP 被风控了。让 L 站走直连，用自己的网络去访问就能过。 Shadowrocket 这样改： 1. 配置页 → 点当前配置 → 编辑配置 2. 进「规则」→ 右上角 + 3. 类型 DOMAIN-SUFFIX，策略 DIRECT，域名填 4. 再加一条，域名填 5. 两条拖到列表靠前，首页全局路由选「配置」，重连一次 然后打开 5 年的 GitHub 账号登录。 GitHub 照常走代理，不受这两条规则影响。 Clash 用户在 rules 里靠前的位置加： - DOMAIN-SUFFIX, - DOMAIN-SUFFIX, 不确定 GitHub 满没满 5 年？打开 created_at。

L女星（飞姐）年轻气盛的时候，仗着干爹的力捧，没少端着架子得罪人，最飘的时候，她对着港圈资本大佬家的电影项目下手，拿着合约吊着当时横行港圈的资本。虽说港圈资本不是项目主导方，不能完全决定谁一定能上，但想不让谁上还是没问题的。 飞姐拍完拿钱就走人，丝毫不提签约的事情，转头还签了国外的公司，这可把港圈资本给气得够呛，对方怎么说也是圈内大哥，自然是不会吃这个哑巴亏，一怒之下就直接下场狙击封杀，随后业内其他被飞姐糊弄过的经纪公司也跟风下场狠踩她。 娱乐圈活跃的几家公司都出手了，飞姐干爹再能干也翻不了天，搞得飞姐那几年在国内就是啥像样的资源都没了。国外公司原本是想通过她打通国内渠道的，却不料绯姐自己把内娱根基挖了，打乱了公司计划，气得高层也是直接翻脸不认人，更没有给飞姐想要的国外资源。 所幸，飞姐也是属于脸在江山在，有情怀粉死忠在一旁摇旗呐喊，加上那些老牌的大公司逐渐落寞，很多冲着利益来的新生代资本方就格外欣赏她，主动上门约合作，她这几年才算是走出了被封杀排挤的尴尬处境。
