Abstract

The American stock market passed a critical phase during 2020. The CBOE volatility index had spiked from a little over 20 to a little over 50 and returned flat to 16% year on year basis. This paper presents a novel model to measure the engagements of retailer trading through public perception and forced media messages. The markets have proved to be resilient on the expected returns in the long term however the short-term spot markets were unpredictable. Even though the Dow Jones fell from 29,100 points to 19,180 points the big investment banks made huge trading profits. Bank of America's trading revenue grew from $3.8 billion to $5.3 billion whereas the retailers went for the bankrupt companies such as Macy's and Hertz. The paper discusses the prediction with help of neural networks and NLP models to analyze retailer's favorite stocks and helps to predict their future expected returns of the stocks. The results of the research create a new key performance index for asset-level risk management using this correlation.

摘要

美国股票市场在2020年经历了一个关键阶段。芝加哥期权交易所波动率指数从略高于20飙升至略高于50,同比持平于16%。本文提出了一种新颖的模型,通过公众认知和强制媒体信息来衡量散户交易的参与度。从长期来看,市场在预期回报方面已被证明具有韧性,然而短期现货市场却不可预测。尽管道琼斯指数从29,100点跌至19,180点,但大型投资银行却获得了巨额交易利润。美国银行的交易收入从38亿美元增长至53亿美元,而散户则盯上了梅西百货和赫兹等破产公司。本文借助神经网络和自然语言处理模型进行预测,以分析散户青睐的股票,并有助于预测这些股票未来的预期回报。研究结果利用这种相关性为资产层面的风险管理创建了一个新的关键绩效指标。
