According to Huang Wenqing, the deputy general manager of Taishin Investment Advisory, the US Treasury Secretary's statements suggest that the toughest phase of the US-China tariff war is likely over. Future uncertainties may hinge on negotiation outcomes, and investors should observe the gap around 20000 points from April 7. As May approaches and chip tariff announcements are anticipated, the stock market may still remain cautious, but the worst scenarios appear to have passed, with potential market reactions to confirmed tariff rates and scopes.
