HSBC downgraded its assessment of U.S. stocks to neutral - in its view, there are many factors in the first half of the year that could have a negative impact on the country's economy. Earlier its recommendation on U.S. stocks was "above market". Now the bank has assigned that rating to European and emerging market equities. Nevertheless, it indicates the risks to the global economy - in particular, if the central banks tighten monetary policy, it could trigger unexpected changes in global economic activity. In this connection HSBC recommends to refrain from closing positions above the market on any risky assets - as analysts consider, it is necessary to wait for more favorable conjuncture. According to experts interrogated by Bloomberg agency, this year the basic risks for the world share market are minimization of programs of purchase of assets by central banks, erroneous course of a monetary policy, continuation of a rough growth of inflation and coronavirus (its strengthening and occurrence of new kinds).
