[Technology stocks sold off due to weak performance, emerging market stock markets fell] On October 30, the performance of technology giants such as Amazon and Intel fell short of expectations, suppressing market risk appetite, and emerging market stock markets weakened. The MSCI Emerging Markets Index fell 1.3% on Friday, and fell more than 2% during the session. The market is worried about huge capital expenditures in the AI ​​field, and corporate performance is lower than expected. Asian stock markets came under significant pressure, with markets with higher technology weights leading the decline. As an important benchmark for global AI trading, South Korea's Composite Stock Price Index fell 16% during the month. Citi strategist Luis Costa and others wrote in a report: "Emerging markets continue to face macro factors that compete with each other. Oil prices, AI market sentiment, and the El Niño cycle may continue to dominate the market." The emerging market currency index fell 0.3%, weakening for the third consecutive day. The sell-off in technology stocks also boosted buying of safe-haven assets such as U.S. Treasuries.
