Analyzing five major Fed rate-cutting cycles since 1990 reveals that not all rate cuts are created equal. While markets currently price in an 83.6% chance of September cuts, history shows the distinction between "preventive" versus "crisis-driven" easing determines market outcomes. From the tech-led rebounds of the 1990s to the liquidity-fueled rally of 2019-2021, each cycle offers lessons for today's concentrated market. With the "Magnificent Seven" representing 30% of U.S. equity market cap, this rate-cutting cycle will likely create winners and losers rather than a universal bull market. Understanding these historical patterns becomes crucial for navigating what appears to be preventive easing in an environment already flush with $7.2 trillion in money market funds.
