Affected by US-Iran conflicts and the prolonged closure of the Strait of Hormuz, global markets are experiencing severe volatility. Major Asian stock indices have repeatedly hit new lows, with South Korea's stock market declining over 6%, and the S&P 500 index falling 5% after 15 trading days. Historical analysis suggests that when geopolitical shocks occur, US stock markets typically find a bottom and rebound around the 15th day, 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%.
