单日暴赚8600万美元!监管详解量化巨头Jane Street如何在印度“割韭菜”
Hua Er Jie Jian Wen· 2025-07-04 12:57
印度监管指控Jane Street恶意操纵印度股市,通过做空银行股指数狂割印度"韭菜"。 周五,印度证券交易委员会指控美国量化交易巨头Jane Street在印度市场实施"恶意操纵计划",要求其上缴5.5亿美元非法所得并实施禁令。这起案件源于 Jane Street与Millennium Management的诉讼案,意外暴露了其在印度期权市场的盈利策略。 监管机构在一份105页的临时禁令中详细披露了Jane Street的操纵手法:先大量买入银行股指数成分股推高指数,再通过期权做空获取巨额利润,仅在2024年 1月17日单日就获利8600万美元。 Jane Street否认相关指控,声称交易是为了管理期权敞口风险。如果该公司将5.5亿美元存入第三方账户,禁令可能被解除。根据印度法律,该公司最终可能 面临高达16.5亿美元的罚款。 此案凸显了量化交易公司在新兴市场面临的监管风险。尽管Jane Street在2023年从印度期权策略中获利10亿美元,但亚洲市场仅占其全球净交易收入的 14%,印度禁令虽然令人尴尬但不会造成致命打击。 三阶段做空路径:先拉升后砸盘 印度证券交易委员会选择2024年1月17日作为详细 ...

Group 1 - The market cannot be precisely predicted, and the goal is to build a cognitive framework to understand its current state and infer short-term evolution [1] - Traditional technical analysis attempts to reduce the complexity of market processes but often overlooks the high-dimensional latent space that drives price movements [1] Group 2 - Early deep learning models like CNNs capture local spatial patterns but fail to understand the path dependency of time series data [2] - LSTM and its variants address the limitations of CNNs by capturing sequential dependencies, but they assume a linear flow of information, which does not reflect the complex interactions in real markets [3] Group 3 - A paradigm shift is needed from sequential dependency modeling to spatio-temporal structural dependency modeling to better capture market dynamics [5] - The core of the proposed approach is a dynamic temporal knowledge graph that models relationships among entities, which is essential for understanding market interactions [6] Group 4 - The use of heterogeneous Hawkes processes allows for modeling event flows within the knowledge graph, capturing the ripple effects of market events [6] - By maximizing the log-likelihood function, the system can derive embedding vectors for entities and relationships, projecting the knowledge graph into a lower-dimensional latent space [7] Group 5 - The model's output is a posterior probability that combines likelihood from data and prior probability based on human insights, emphasizing the importance of human judgment in the decision-making process [9][10] - The company aims to create a decision framework that optimizes long-term expected value rather than focusing on short-term gains, leveraging the cognitive spread between its insights and market averages [11]
