美联储若将降息，港股历史表现如何？

Group 1: Federal Reserve Rate Cut Expectations - The market anticipates the Federal Reserve will initiate a rate cut in September, with discussions focusing on the magnitude of the cut, speculated to be between 25 to 75 basis points, with a 74% probability for a 75 basis point cut as of September 14, 2025[2][11] - Historical data indicates that Hong Kong stocks are more sensitive to changes in U.S. monetary policy due to the linked exchange rate system between the Hong Kong dollar and the U.S. dollar[10] Group 2: Historical Performance of Hong Kong Indices - In previous rate cut cycles, the three major Hong Kong indices (Hang Seng Index, Hang Seng Tech Index, Hang Seng China Enterprises Index) typically exhibit a volatile pattern in the 30 trading days leading up to the cut, followed by a period of adjustment post-cut[22][29] - The Hang Seng Tech Index tends to show smaller declines immediately after a rate cut and greater gains in the subsequent period compared to the other indices[29][31] Group 3: Market Reactions Post Rate Cut - On average, the three indices tend to decline in the two trading days before the cut, rise on the day before, and then drop on the day of the cut and the following two days[33][39] - After a rate cut, the Hang Seng Tech Index has historically shown a stronger recovery, with average returns of 1.03% in the four weeks following the cut, compared to 0.08% for the Hang Seng Index[19][24] Group 4: Comparison with Previous Rate Cut Cycles - The current environment is more complex than previous rate cut cycles in 2019 and 2024, with persistent inflation and economic slowdown concerns[49][51] - Historical examples of "recessionary rate cuts" show that the performance of the indices can vary significantly based on economic fundamentals and corporate earnings, indicating that a recessionary context does not guarantee a decline in stock prices[56][62] Group 5: Risk Factors - Potential risks include historical data bias, extrapolation risks, and the possibility that the magnitude and frequency of rate cuts may be lower than expected[61]
