"Santa Claus is afraid to hang out?" This week the Federal Reserve's silent period continues, and the volatility at the beginning of December focuses on the performance of retail and cloud computing leaders.

According to the Securities Times app, the last month of the year will begin on Monday. Investors hope that this month can end smoothly, drawing a close to the year.
