S&P 500 and Nasdaq Extend Wins as Markets Brace for Fed Decision and Alphabet, Microsoft Earnings

The Quick Take

• S&P 500 and Nasdaq gained for a second consecutive session ahead of the Federal Reserve's rate decision
• Alphabet and Microsoft earnings, due after market close, will test investor assumptions about AI cash flow and demand outlook
• Concerns over big tech capital expenditure and AI spending trajectory are central to market positioning

US equity markets extended their winning streak into a second session, with the S&P 500 and Nasdaq advancing as investors positioned ahead of two macro-defining events: the Federal Reserve's rate decision and the earnings releases from Alphabet and Microsoft. The dual catalysts created a risk-on environment where market participants balanced optimism about AI-driven revenue growth at major tech names against concerns about elevated capital expenditure commitments and whether AI monetization is matching the investment pace. With both events scheduled to resolve in the same trading session, the market was essentially holding its breath — rallying on expectation while preparing for significant volatility on the results.

The earnings releases from Alphabet and Microsoft carry disproportionate weight for global equity market direction. Together they represent a significant portion of the S&P 500 market cap, and their AI spending disclosures — capex guidance, cloud revenue growth, and AI-product adoption rates — will set the tone for the entire technology sector's valuation framework entering Q4. A beat-and-raise scenario from either company could trigger a relief rally in global tech indices, while concerns about AI ROI or margin compression from higher spend would ripple into semiconductor names, cloud infrastructure vendors, and Indian IT outsourcing firms exposed to big tech client budgets.

Watch the Federal Reserve's statement language closely: any shift toward a more accommodative tone — particularly around the timing of rate cuts — would validate the equity market rally and provide a secondary tailwind for growth stocks already positioned for AI-driven earnings upside. The macro variable that determines whether the current market advance holds is the combination of Fed guidance and big tech earnings quality. An Alphabet search revenue miss combined with a hawkish Fed hold would be the worst-case scenario for risk assets in the near term, potentially reversing two sessions of gains rapidly.
