Commenting on the current market context, analysts from VDSC Securities Company believe that the current market valuation is suitable for long-term stock accumulation.
However, in order to deal with increasing uncertainty and potential economic risks, VDSC experts think that the defensive portfolio allocation strategy will be suitable in the current period.
"In the short term, the transaction will still be favorable, reinforced by positive business results and good liquidity. However, investors also need to pay attention to the unexpected risks from the results of tariff negotiations. Measures including increasing purchasing power or opening risk-off positions through futures contracts may be considered at times before major events take place to minimize damage to the portfolio," VDSC recommended.
