FOMC Looms: 'Irrational Exhuberance' 2.0?

Wall Street anticipates a pivotal FOMC meeting, with a 25-basis point interest rate cut overwhelmingly expected (90-96% probability) despite healthy Q2 GDP growth and elevated inflation. This expected cut is influenced by recent negative job revisions and the Fed's shift to a flexible inflation-targeting framework, occurring amidst presidential pressure. While significant market volatility is expected around the decision and monthly options expiration, historical data suggests rate cuts near market highs and strong momentum (S&P 500 up >30% in five months) have consistently led to substantial further gains, potentially fueling an AI-led rally.

Analysis

The market is positioned for a pivotal Federal Open Market Committee (FOMC) meeting where a 25-basis point interest rate cut is overwhelmingly anticipated, with CME FedWatch and PolyMarket pricing in 96% and 90% probabilities, respectively. This expectation persists despite conflicting macroeconomic data, including healthy Q2 GDP growth of 3.3% and inflation running approximately 1% above the Federal Reserve's target. The catalyst for the expected cut appears to be a significant downward revision in job growth, which saw 911,000 fewer jobs created through March 2025 than initially reported, coupled with Chairman Powell's recent signal of a more flexible inflation-targeting framework. In the immediate term, elevated volatility is expected due to the FOMC decision itself, which historically induces market swings of around 1%, and the coinciding monthly options expiration (OPEX). Furthermore, with the Nasdaq 100 having rallied for ten consecutive days, the setup is ripe for a potential 'sell the news' event, amplified by historically weak late-September seasonality. However, the long-term outlook appears strongly bullish based on historical precedent. Data from JP Morgan shows that in all 12 instances where the Fed cut rates with the S&P 500 within 1% of its all-time high, the market was higher one year later with a median return of 15%. This is reinforced by momentum data from Carson Research, indicating that the S&P 500's 30% rise in five months has, in 100% of past occurrences since 1975, led to positive returns over the next 6 and 12 months, with an average 12-month gain of 18.1%. This backdrop, combined with a contrarian bullish signal from the AAII Sentiment Survey showing more bearish than bullish investors, suggests a potential for a sustained rally led by AI-related equities such as Nvidia, Microsoft, and Oracle.

Key Decisions for Investors

• Investors should brace for heightened short-term market volatility around the FOMC announcement and consider using derivatives or adjusting position sizes to hedge against potential price swings driven by the event and OPEX.
• Despite near-term risks, the powerful historical data supporting market gains following rate cuts near all-time highs suggests that any significant pullback should be viewed as a strategic buying opportunity for long-term portfolios.
• Consider overweighting exposure to the artificial intelligence sector, particularly market leaders like NVDA, MSFT, and ORCL, which are positioned to lead the market should the bullish historical precedent for a post-cut rally materialize.
• Monitor contrarian sentiment indicators, as the current fearful positioning shown in the AAII survey could provide additional fuel for a market advance if sentiment begins to shift positive.
