The final trading session of the last trading week on the U.S. stock market resulted in a fall of key indices within 1.5 percent. Major selling was seen in the Technology and Retail sectors. The incoming news about the resumption of some concerns related to COVID-19 made investors somewhat reconsider their risk appetite and reduce the share of risky instruments in their portfolios. Moreover, the proximity of the financial year end and some uncertainty with inflation expectations also reduces the optimistic mood of participants, forcing them to sell. However, the volume of trades looks rather small, that speaks about possible short-life of such sales at appearance of positive news on the market.
