Fall 2021 started with a rebound amid seesaw dynamics in the US Stock Markets. As expected, as Fall approached, the stock market momentum that started in early May 2021 had been slowing down, with the increasing volatility and major impact of unexpected news. The factors that  have affected the overal market since early 2021, such as COVID-19 pandemic new waves,  the job market, the growing inflation, Chinese government actions on Tech and e-commerce companies, and the overall economic policies appear to have finally caught up with the market. These factors appeared to be the driver of the observed sell-offs. Then two major events happened:  unexpected negative news on China Evergrande Group and  encouraging news from the US FedReserve meeting.  

AroniSmart™ team, leveraging the Machine Learning, Big Data, Data Science, Bayesian Network Analysis, Neural Network Analysis, Text Analytics, and Sentiment and Valence Analysis capabilities of the new improved  AroniSmartInvest™ and AroniSmartIntelligence™,   looked at the stock performance, market sentiment index and events driving the stock market as of September 23, 2021 ( For More on AroniSoft LLC and AroniSmart products click here).  The key stocks driving the market at the end of Summer 2021 were identified.

On September 19, 2021, news emerged about the China's heavily-indebted Evergrande Group.  According to the news, Evergrande was due to pay $83.5 million in interest on a dollar-denominated bond and additional significant funds on a yen-denominated bond. News pointed to a potential default for both bonds. Following the news on Evergrande,  the key stock market indices registered heavy losses, adding to previous growing sell-offs after weeks of record performances (Dow Jones Industrial Average (^DJI) lost 3.21%, Nasdaq (^IXIC): 3.33 %, S&P 500(^GSPC): 2.93%, and Russel 2000 (^RUT) lost  3.40%).

Then on Wednesday,  September 21, 2021, the meeting of the US Federal Reserve Bank was held. In the meeting, key major plans and signals were announced, including shifting away from the pandemic financial support and rolling back the related stimulus and potential actions related to bonds and interest rate. By the end of the day on Thursday, September 23, 2021, the stock market was back to near records highs.  Compared to the week before, the stock performance was back to near record territories, with gains across the board:   Dow Jones Industrial Average (^DJI):  +0.67%; Nasdaq (^IXIC): +0.38 %; S&P 500 (^GSPC): +0.15%; and Russel 2000 (^RUT): +1.82%).
