Afternoon mutation, what happened?

On September 6th, today, large financial stocks once strengthened and then fell back. The three major indices fell unilaterally in the afternoon. What exactly happened? First, funds pulled up financial heavyweights today, and the volume and energy were not significantly amplified. Financial large-cap stocks rose and fell, and there was a seesaw effect. Other hot sectors also corrected. Second, the wide-based ETFs that were active in the early stage today did not increase significantly in volume in the afternoon. Recently, the market has paid more attention to wide-based ETFs. Third, the peripheral market generally fell. Fourth, the main contract of the container shipping index (European Line) fell by more than 7% today, and it once fell by more than 10% during the session. Since the beginning of this year, the index has continued to decline due to the recent weakening of overseas demand, which has triggered market concerns about the global economy.
