Affected by the US-Iran conflict and the prolonged closure of the Strait of Hormuz, global markets have experienced severe volatility. Major Asian stock indices have repeatedly hit new lows, with the Korean stock market declining more than 6%, and the S&P 500 index falling 5% after 15 trading days. Historical analysis shows that when geopolitical shocks occur, the US stock market typically rebounds after touching bottom around day 15, which may lay the foundation for subsequent recovery. Currently, S&P 500 index futures are down 0.7%, Nasdaq 100 index futures are down 0.7%, and Dow Jones index futures are down 0.6%.
