20. 随机交易策略优于技术策略吗?
from 知为谁 · host 知为谁
今天我们讨论的来源研究了金融市场中的随机性,并探讨了随机交易策略的表现是否优于技术策略。作者通过分析四个主要的国际股票市场指数(FTSE-UK、FTSE-MIB、DAX和S&P500)近15-20年的历史数据,比较了包括随机策略在内的五种不同交易策略的预测能力。研究发现,在长期来看,所有策略的平均胜率都接近50%,与随机策略的表现相似,但在短期内波动性较大。此外,随机策略的波动性通常小于其他技术策略,这意味着随机策略的风险较低。这些发现挑战了传统的高效市场假说,并提出了随机干预可能有助于稳定市场的政策启示。内容来源:https://arxiv.org/pdf/1303.4351
