On April 19, 2021, the stock market sentiment remains positive. However, investors appear to have started focusing on one of the key questions: what is coming next? The answer to the question remains elusive, especially after the up and down movements, around an overall upward trend,  observed since the beginning of the year.   In the previous analyses,  AroniSmart™ team has shown major positive signs at the start of Q2 2021, looking at  the volatility dynamics  observed in March and February 2021,  (see some dynamics here: )

On April 19, 2021 the stock market performance appears to be impacted  by factors similar to those that were driving the volatility as of April 2, 2021:  speculative considerations on the economy,  profit taking,  bonds prices,  interest rates,  options trading, political agenda, and  related news about some key stocks, especially those related to Electic Vehicules (EV) Technology, Solar Energy, Cryptocurrency, Retail, and Banking.

As of the closing hour of April 16, 2021 the key stock market indices continued to register gains ( Dow Jones Industrial Average gained 1.49%, Nasdaq  1.59 %, S&P 500 2.063%). AroniSmart™ team, leveraging the Machine Learning, Big Data, 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 in April 2021 ( For More on AroniSoft LLC and AroniSmart products click here). 

AroniSmart™ team  continues to build on earlier analyses in  2021. The analyses reinforce the fact that the market sentiment remains in the negative territory,  as investors appear to continue struggling with uncertainty and volatility and both upbeat and downbeat expectations. At the same time, there is growing confidence following the clearing views about the direction of the market, as the crisis is being addressed by political and economic decision makers.

As depicted in the Words Cloud and Tags view above,  it was found that the the positivity (see words in green) continues to be driven by words such as  health, work, good, proper, gain, improv, innov, interest, gain, relief, strong, etc. The words cloud points to the improving companies earnings, healthcare, the performance of the stock market, COVID-19 vaccinations,  new innovations such as EV and 5G, Solar Energy, and the continued government support to improve economic performance.
