英文摘要:
Following a Geometrical Brownian Motion extension into an Irrational Fractional Brownian Motion model, we re-examine agent behaviour reacting to time dependent news on the log-returns thereby modifying a financial market evolution. We specifically discuss the role of financial news or economic information positive or negative feedback of such irrational (or contrarian) agents upon the price evolution. We observe a kink-like effect reminiscent of soliton behaviour, suggesting how analysts\' forecasts errors induce stock prices to adjust accordingly, thereby proposing a measure of the irrational force in a market.

中文摘要:
在几何布朗运动扩展到非理性分数布朗运动模型之后,我们重新研究了代理人对对数收益上的时间相关新闻的反应行为,从而修改了金融市场的演化。我们特别讨论了金融新闻或经济信息的作用,这些非理性(或反向)代理人对价格演变的正面或负面反馈。我们观察到一种类似孤子行为的扭结效应,这表明分析师的预测错误是如何导致股价相应调整的,从而提出了一种衡量市场非理性力量的方法。
