英文摘要:
We applied the Johansen-Ledoit-Sornette (JLS) model to detect possible bubbles and crashes related to the Brexit/Bremain referendum scheduled for 23rd June 2016. Our implementation includes an enhanced model calibration using Genetic Algorithms. We selected a few historical financial series sensitive to the Brexit/Bremain scenario, representative of multiple asset classes. We found that equity and currency asset classes show no bubble signals, while rates, credit and real estate show super-exponential behaviour and instabilities typical of bubble regime. Our study suggests that, under the JLS model, equity and currency markets do not expect crashes or sharp rises following the referendum results. Instead, rates and credit markets consider the referendum a risky event, expecting either a Bremain scenario or a Brexit scenario edulcorated by central banks intervention. In the case of real estate, a crash is expected, but its relationship with the referendum results is unclear.

中文摘要:
我们应用Johansen Ledoit Sornette(JLS)模型来检测与计划于2016年6月23日举行的英国脱欧/脱欧公投相关的可能泡沫和崩溃。我们的实现包括使用遗传算法的增强模型校准。我们选择了一些对脱欧/脱欧情景敏感的历史金融系列,代表多种资产类别。我们发现,股票和货币资产类别没有显示泡沫信号,而利率、信贷和房地产表现出超指数行为和泡沫机制的典型不稳定性。我们的研究表明,在JLS模型下,股市和外汇市场预计不会在公投结果公布后崩溃或大幅上涨。相反,利率和信贷市场认为公投是一个风险事件,预计要么出现英国脱欧的情景,要么出现由央行干预的脱欧情景。就房地产而言,预计会发生崩盘,但其与公投结果的关系尚不清楚。
