Does weakening demand-side performance amid thriving capital spending signal a boom's end?
Core argument: In late 1999 and early 2000, communications services companies including Verizon, AT&T, WorldCom, Bell South, GTE and Sprint rolled over even as communications equipment stocks such as Cisco, Nokia, Nortel, Qualcomm and Motorola kept rising.
The worrisome part of a boom cycle is when companies closest to final demand roll over, even as capital spending beneficiaries of the cycle keep on thriving. In late 1999 and early 2000, communications services companies rolled over (Verizon, AT&T, WorldCom, Bell South, GTE, Sprint) even as communications equipment company stocks (Cisco, Nokia, Nortel, Qualcomm, Motorola) kept on rising. The obvious parallel to today is soaring stock prices and free cash flow for semiconductor companies (the caboose) even as the front end of the train (hyperscalers) is seeing stock prices stagnate and free cash flow plummet. Tech sector earnings typically track reasonably well with sectors that rely heavily on technology (finance, manufacturing, media, transport, and healthcare) and pay for all that equipment and software. The recent divergence begs the question: who is going to pay for the AI boom if the tech sector’s primary customers are not making more money as well?
