American stock indices finished the trading session on the plus side - at the end of the day Dow Jones grew by 1.81%, S&P 500 - 1.17%, NASDAQ - 0.85%. The mood in the stock exchanges became more optimistic after the release of the US economic statistics, which showed that the latter demonstrated the overall growth. This somewhat tempered concerns about the emergence of a new type of coronavirus. According to Interactive Investor analyst Richard Hunter's assessment, however, there is still uncertainty on trading floors because of the risk of renewed lockdowns, which could trigger a new strain. That, in turn, would deal an additional blow to the global economy. Now, according to experts, we should prepare for stronger fluctuations in the market, as there is high uncertainty about further development of the situation. Meanwhile, players' attention is focused on the upcoming release of important statistics in the United States - inflation data for November and the results of the Federal Reserve System meeting. The first figure will be released on the 10th and the regulator's results will be released next week. Players also expect the latter to assess the prospects for the U.S. economy.
