Morgan Stanley(US:MS) 美股IPO·2025-10-20 12:37Core Insights - Morgan Stanley's research indicates that extreme "resonance" among the S&P 500, U.S. Treasury yields, and the U.S. dollar index often predicts a reversal in the dollar's strong cycle [3][7] - The analysis of the past 25 years shows two strong signals for a weaker dollar in the next six months: the "Goldilocks" scenario and the "Broad Up" scenario [3][10] Group 1: Goldilocks Scenario - The "Goldilocks" scenario occurs when the S&P 500 rises over 1.25 standard deviations while both the dollar index and Treasury yields fall over 1.25 standard deviations [8][15] - This scenario has appeared 12 times in the past 25 years, leading to an average dollar index decline of 3.3% over six months, with an 83% success rate for predicting dollar weakness [10][15] - The strong performance of the British pound in this scenario may reflect expectations of a soft landing for the economy [6][15] Group 2: Broad Up Scenario - The "Broad Up" scenario is characterized by simultaneous increases in the S&P 500, dollar index, and Treasury yields, each exceeding 1.25 standard deviations [16][20] - This scenario has occurred 26 times in the past 25 years, resulting in an average dollar index decline of 2.7% over six months, with a moderate success rate of 73% [16][20] - The occurrence of this scenario suggests a phase of global economic catch-up following a period of U.S. exceptionalism, with the Australian dollar often performing well during synchronized global economic recovery [20]
