The Federal Reserve's unexpected policy shift has triggered significant market volatility, with the odds of a 12-month rate cut surging by 40 percentage points to 102%. This dramatic change follows a reversal from the Fed's previously hawkish stance, raising concerns about the central bank's communication strategy. The market's response has been robust, with the S&P 500 and Russell 2000 indices experiencing their strongest five-day gains since April. This broad-based rally, driven by increased trading volume, suggests a genuine buying trend rather than a temporary oversold bounce. The participation of various sectors, including regional banks and small caps, underscores the strength of the market rebound.
