Major U.S. stock indices were mostly down on Tuesday. The Dow Jones and S&P 500 ended trading down 0.032% and 0.11%, respectively, while the NASDAQ was up 0.14%. The dynamic reversed after a rally on Monday, during which the Dow Jones reached a record high. Lately the indexes have been actively growing - investors' optimism was bolstered by hopes for approval of a new $1.9 trillion support package. At the same time volatility in the stock market has increased - the CBOE index, which measured more than 37p in late January, has fallen below 22p this week. In general, according to Trevor Gritsam, head of diversified investments at Royal London Asset Management, players are set for positive results from new economic support measures. He believes the market's growth will also be supported by the proliferation of coronavirus vaccines. He also outlined two major threats to the economic recovery - the emergence of new mutations and a sharp rise in inflation.
