The call
Capital Economics released a research note on 29 October saying the AI trade may or may not be in a bubble, but investors still need defensive areas to hide if the market bursts. The firm — which correctly called a bearish view on the AI trade in early September, warning the 'AI equity boom is nearing an end' — now forecasts the S&P 500 will eventually fall to 6,500 by the end of 2027 if air continues to leak from the trade or if the bubble bursts. That would equal roughly a 16% decline from current levels.
Before the reckoning, however, the firm expects a final rally in the stock market this year, led by tech stocks. The advice is about positioning for the next 12 months: 'defensive sectors may be the place to hide.'
Where to hide
Capital Economics sees US Treasury yields as a vital counterbalance in an AI bust. The firm expects yields to drop, pushing bond prices higher, and notes the 10-year yield fell all eight times since 1995 when the PHLX Semiconductor Sector Index (SOX) dropped 35% or more.
If yields fall, real estate would benefit: unlike energy and financials, it has fared much better when SOX selloffs coincided with falling yields. But even there, real estate would still fall, just less than the market. The firm calls consumer staples the even better defensive sector to 'ride out the AI bust' — the sector made good gains after the tech peak in early 2000.
Why energy and financials won't save you
Capital Economics explicitly pushes back on the idea that energy and financials are safe havens this time. Both groups 'have done much better' now than they did before past technology selloffs — but that is not because they are insulated from AI.
The reason is repeated supply shocks, especially for energy commodities, which have lifted energy prices and, relatedly, Treasury yields. If the AI boom turns to bust and those dynamics reverse, the assumption that energy and financials will hold up falls apart. The firms that have done best in past tech selloffs were true defensives, not cyclical sectors.
The larger context
The note arrives amid intense investor concern that megacap tech companies — Meta, Microsoft, Amazon and Alphabet — are spending billions on AI infrastructure without adequate returns. Elevated capital expenditures have eaten into hyperscalers' cash flows and profits: Alphabet's third-quarter earnings showed negative free cash flow, and Meta reported negative free cash flow while raising its full-year capex commitment.
This is the same fundamental worry driving the Eisman tipping-point commentary and the neocloud financing squeeze: the AI buildout is real and large, but the returns are not yet visible in the financial statements. Capital Economics' defensive-sector advice is the conservative institutional response to that uncertainty.
Caveats
The 6,500 forecast is a scenario, not a base case, and depends on how quickly AI sentiment unwinds. Capital Economics itself expects a final rally before any reckoning, so the defensive shift is a hedge rather than an immediate call.
Past patterns with the 10-year yield and SOX do not guarantee future behavior, and consumer staples and real estate carry their own valuation and rate risks. The analysis is a top-down sector view, not specific security recommendations.
The market backdrop
The note lands at a moment when every major market observer is asking the same question: how much of the S&P 500's gains are tied to AI capex, and what happens when the spending slows? Capital Economics' 'AI equity boom is nearing an end' call in early September was one of the first from a mainstream research house, and it has been joined since by investor commentary from figures like Steve Eisman, who told CNBC the trade is near a 'tipping point.'
Execution risk is the other side of the story. Mega-cap hyperscalers are building out data centers at a pace that has produced record quarterly capex numbers, but also negative free cash flow at Alphabet and Meta. Bond markets are pricing in the strain — CoreWeave bond yields have hit 15%, a level associated with distressed credit. The combination of stretched equity valuations, negative free cash flow and rising financing costs is what makes the defensive playbook relevant now rather than hypothetical.
What could go wrong with the plan
A pure defensive rotation has its own failure modes. Consumer staples are not cheap after years of being a crowded safe-haven trade, and a traditional reflation could hit bond prices and, with them, rate-sensitive real estate. If the AI reckoning is mild — a 10% drawdown rather than a 40% one — staying in tech could outperform a defensive posture, as it did for much of 2026.
The plan also assumes the AI trade unwinds gradually enough for investors to rotate before the fall. History suggests tech selloffs can be abrupt. Capital Economics' point is not that the defensive sectors are great on their own merits, but that they are the least-bad option when the SOX falls and yields follow. That conditional framing is the honest way to read the note.
Common questions
What does Capital Economics forecast?
The S&P 500 could fall to 6,500 by the end of 2027 if the AI trade deflates — a roughly 16% decline.
Where should investors hide?
Consumer staples and real estate, with Treasury yields expected to fall during any tech selloff.
Why not energy and financials?
Their recent strength comes from energy supply shocks and higher yields, not insulation from AI — dynamics that would reverse in an AI bust.
