Nvidia stock was in something of a short-term slump on Tuesday, closing the day at $103.73, down 26% from the all-time high set in June. Then Microsoft released its quarterly earnings.
The big picture: Microsoft announced a larger-than-expected $19 billion of capital expenditures in Q2 — that's $300 million per business day — and said "nearly all" of that was spent on building cloud and AI infrastructure.
Nvidia shares immediately surged, on the basis that the chipmaker is surely the prime beneficiary of Microsoft's spending spree.
Between the lines: Microsoft and Nvidia have been the joint avatars of the AI stock-market boom over the past year. Since the beginning of 2023, Microsoft stock is up 74%, while Nvidia is up 701%.
The bottom line: Wednesday's market action is a sign that the market is beginning to concentrate on cash flow and that the fortunes of the two companies might no longer be entirely aligned.
