This week is not complicated, but it is unforgiving. Microsoft and Alphabet report Wednesday after the close, hours after the Federal Reserve announces its decision at 2:00 p.m. ET. Amazon and Intel follow Thursday, the same day as the advance estimate of third-quarter GDP. That density of events is what makes the next 48 hours matter more than any single earnings result.
Meta already showed the cost of getting this wrong. On October 22, after Meta raised the floor of its 2026 capex guidance to $135 billion and posted negative free cash flow in the third quarter, the Nasdaq dropped 2.6%, its worst session since June, and the Philadelphia Semiconductor Index fell about 6.7%.
The three hyperscalers reporting this week are spending at a scale that makes Meta’s number look modest. Microsoft is tracking toward $190 billion in capital expenditures for calendar 2026. Alphabet has guided to $195 billion to $205 billion. Amazon raised its 2026 capex to $220 billion in July, with CEO Andy Jassy saying the company still will not have enough capacity to meet demand in 2026 or 2027. Every call this week is a vote on whether that spending is justified.
Where to Focus Wednesday
Alphabet is the higher-conviction read. Google Cloud grew 82% year over year in Q2, operating margin reached 35.6%, and backlog hit $514 billion. The sequencing matters: the Fed statement lands at 2:00 p.m., Alphabet’s call starts at 4:30 p.m. Shares may absorb two separate macro events within a single afternoon. Position size accordingly.
Microsoft guided Azure and other cloud services revenue to growth of approximately 45% in constant currency for Q1 FY27. The secondary watch is gross margin, which has been under pressure as AI infrastructure costs rise. A revenue beat alongside further margin pressure can still send the stock lower.
Thursday’s Different Calculus
AWS grew 37% year over year in Q2, its fastest pace in 18 quarters, and the contracted backlog reached $496 billion. Demand is not in question. The number to watch Thursday is whether Jassy signals any change to 2027 capex expectations and how that lands against current free cash flow trajectory.
Intel is the overlooked entry point. Its Data Center and AI division grew 59% in Q2. That divergence is worth monitoring in a week the hyperscaler calls will dominate.
The Plan
FactSet’s October 23 update shows the S&P 500 is still on pace for better than 25% year-over-year earnings growth for Q3, with only a fraction of the index reported so far. The macro backdrop is intact. The risk this week is entirely sequencing. Trim index-level exposure before the Wednesday 2:00 p.m. window, prioritize cloud margin and 2027 guidance commentary on the evening calls, and treat Intel’s pullback as the cleaner, lower-correlation trade of the week.
