Wall Street set for monthly gains after Amazon's strong outlook

U.S. stock indexes advanced, poised for a strong October close, as Amazon's upbeat earnings forecast and robust cloud revenue growth eased concerns over Big Tech's AI spending, with Apple also providing a strong iPhone sales outlook. This positive momentum, coupled with 83.2% of S&P 500 companies beating Q3 earnings estimates, contributed to multi-month consecutive gains for major indices. However, market expectations for a December Fed rate cut have significantly recalibrated, dropping to 67.9% from 91% a week prior, following the Fed's recent quarter-point cut and cautious forward guidance.

Analysis

U.S. stock indexes demonstrated robust performance, poised for significant monthly gains, with the S&P 500 up 2.7% for October, marking its sixth consecutive monthly advance. This positive momentum was largely driven by strong corporate earnings, particularly from Big Tech. Amazon's shares surged 10.6% to an all-time high following an upbeat quarterly sales forecast and cloud revenue growth, which eased broader concerns regarding AI infrastructure spending. Apple's holiday quarter iPhone sales forecast also surpassed Wall Street expectations.

Beyond Big Tech, the overall third-quarter earnings season has been exceptionally strong, with 83.2% of S&P 500 companies surpassing analysts' estimates, significantly above the historical average of 67%. This broad-based outperformance contributed to the market's upward trajectory. Other notable movers included First Solar, which surged 12.6% on strong Q3 sales, and Western Digital, reaching an all-time high after beating earnings forecasts.

Despite the positive earnings backdrop, market expectations for future monetary policy have recalibrated. While the Federal Reserve delivered an expected quarter-point rate cut, its cautious forward guidance has led traders to pare bets on a December cut, with futures now pricing a 67.9% chance, down sharply from 91% a week prior. This shift, coupled with dissenting views from regional Fed presidents regarding inflation and labor market strength, introduces a degree of uncertainty regarding the pace of future easing.

Key Decisions for Investors

• Investors should prioritize companies demonstrating strong fundamental performance and positive guidance, especially those leveraging cloud and AI effectively, given the robust Q3 earnings season and Amazon's outperformance.
• Closely monitor Federal Reserve communications and upcoming economic data, as the recalibration of December rate cut expectations introduces uncertainty regarding the future trajectory of monetary policy.
• Evaluate individual companies' AI investment strategies for clear return on investment, as market sentiment remains mixed on the impact of heavy AI spending, despite some concerns being eased by Amazon's results.
