PESSIMISM IS SPREADING, THE FED RATE HIKE PROCESS REMAINS UNCHANGED, AND A CORRECTION OF THE STOCK MARKET IS STILL NECESSARY IN THE MEDIUM TERM. But the stock market is not likely to fall every day. After falling, there is a need for a rebound, hitting the GMMA level in December 2018 and March 2020. Compared to this time, there is a strong support between 270-280. As a friend who likes to trade short lines, can you seize this opportunity and make a rebound?!
