AI is carrying the market while a weaker economy changes which ETFs make sense

The point isn’t to permanently avoid small caps, REITs, dividend stocks or even AI-heavy ETFs. The conditions can change.

For VIOV, the signal to watch is lower borrowing costs combined with evidence that the economy is slowing without falling into a deep recession. If Treasury yields begin falling materially and small-cap earnings stop deteriorating, the case for small-cap value gets much better. A rotation out of mega-cap technology would add another confirmation.

For VNQ, the trigger is clearer: falling long-term interest rates and stabilizing real estate conditions. If the 10-year Treasury moves decisively lower, mortgage rates follow and refinancing pressure begins easing, REITs could move from one of the more difficult areas of the market to one of the more interesting ones.

For VYM, the setup improves when investors no longer receive roughly 5% from Treasuries while taking equity risk for a similar income stream. Falling Treasury yields would make dividend stocks relatively more attractive. Evidence that companies are maintaining or increasing dividends during an economic slowdown would strengthen the case.

For VIOV, VNQ and VYM, I would therefore watch the 10-year Treasury more closely than the Federal Reserve’s headline rate. Long-term borrowing costs are what directly affect valuations, financing and the competition from bonds.

VUG, VGT and QQQM require a different test.

They don’t become attractive again simply because their prices fall.

The crucial question is whether AI spending is turning into earnings.

If semiconductor demand remains strong, cloud and data-center spending continues producing revenue, AI companies demonstrate improving economics and the enormous capital expenditures begin generating measurable profits, then a technology selloff could become an opportunity rather than a warning.

But if AI revenue expectations keep getting cut while companies continue borrowing enormous amounts of money to build infrastructure, a lower share price by itself would not be enough.

That distinction is especially important now.

On October 8, Reuters reported that OpenAI’s annualized revenue expectation had fallen to about $50 billion from a previous expectation of $70 billion, while AI-related companies continue pursuing enormous financing commitments. At the same time, semiconductor stocks had already gained more than 80% in 2026 before the latest selloff.

That creates a simple test for VGT, VUG and QQQM:

AI profits rising faster than AI spending = the bull case remains intact.

AI spending rising faster than AI profits = the risk is increasing.

For VTI and VOO, I would not wait for a perfect economic signal. These are broad-market funds and can be accumulated through a long-term strategy even when the economy is weakening. The bigger question is how aggressively to add when valuations are high and the market is being carried by a narrow group of companies.

VXUS becomes more attractive if U.S. valuations remain elevated while international earnings and economic conditions improve. VWO needs an even higher bar because currency, geopolitical and emerging-market risks can overwhelm a valuation argument.

So the “time to buy” isn’t one magic number.

I’d watch five things:

1. 10-year Treasury yield: A sustained decline would improve the setup for VIOV and VNQ and reduce pressure on growth-stock valuations.

2. AI earnings versus AI spending: Rising AI revenue and profits would support VUG, VGT and QQQM. Falling revenue expectations while capital spending keeps exploding would be a warning.

3. Employment: If unemployment rises gradually while inflation cools, that could create the conditions for lower rates without a severe recession. A rapid deterioration in employment would be a different signal.

4. Housing: Stabilizing home sales, construction and refinancing conditions would improve the case for VNQ and small-cap stocks.

5. Market breadth: If fewer and fewer mega-cap technology stocks are responsible for the market’s gains, that is a warning. If leadership begins spreading into small caps, value stocks and international markets, it would provide evidence that the rally is broadening.

That gives investors something much more useful than “buy these ETFs” or “don’t buy these ETFs.”

The environment is changing.

If AI continues producing real earnings while rates remain high, the AI-heavy funds can continue winning.

If the economy weakens enough to bring inflation and long-term yields down, the opportunity can start shifting toward small caps, real estate and other rate-sensitive areas.

And if both the economy and AI earnings deteriorate at the same time, none of these equity ETFs suddenly becomes safe just because the price has fallen.

The objective is to recognize which condition is actually developing before deciding which ETF deserves the next dollar.
