Yardeni Research Flags Four Shocks That Could Create Buying Windows

Yardeni Research has pushed its 8,400-point S&P 500 target from the end of 2026 to mid-2027, setting 7,900 as the new year-end goal, and identified four shocks that could hand investors buying opportunities in the coming weeks.

Ed Yardeni and Elias Griepentrog laid out the analysis in a Sunday note. Their advice was blunt: get ready to buy the scares.

The strategists flagged four surprises to watch. Each one could trigger a selloff. Each selloff, in their view, could become an entry point for investors holding cash.

Why did Yardeni cut the timeline on its S&P 500 target?

The decision to stretch the 8,400 target from end-2026 to mid-2027, with 7,900 now penciled in for year-end, reflects four pressures on valuation multiples:

• Rising bond yields
• Worsening geopolitical tensions
• The funding of artificial intelligence
• Political uncertainty in the U.S.

"Our cautiousness reflects concerns about valuations, not about economic growth or corporate earnings," Yardeni and Griepentrog said. "We expect the economic expansion and the bull market to remain intact as the Roaring 2020s continue."

That distinction drives the whole note. The strategists see risks in what investors pay for stocks, not in what companies earn.

What role does the Iran war play?

The first shock concerns how the war in Iran might unfold. Fighting may be about to resume, the strategists wrote. Yardeni Research rates this as highly likely, on two grounds: neither side appears ready to concede, and Tehran may aim to weaken President Donald Trump's political popularity ahead of the midterm elections.

Geopolitical crises generally cause temporary panics, they noted. If the U.S. economy stays strong, those panics could prove attractive entry points.

Could the Fed actually raise rates?

The second shock is a Federal Reserve surprise. The central bank could raise interest rates by one-quarter point at its meeting on Wednesday — despite the market pricing in a 91% chance of a hold, according to FedWatch. Alternatively, it could move by 50 basis points when it convenes in December.

Either move could push Treasury yields higher, the strategists said. That would compress stock multiples and drive risk-off behavior across markets. But they argued the initial reaction would rest on the surprise itself, not on economic fundamentals.

"After all, additional tightening would reflect the economy's resilience and the Fed's determination to contain inflation, and the policy rate would likely remain in accommodative territory," they said. "Any resulting selloff therefore could offer another buying opportunity."

What about the midterm elections?

The third potential event is a surprise result from the U.S. midterm elections in November. Betting markets have increasingly forecast a Democratic Party sweep, yet Yardeni and Griepentrog said investors have not fully discounted what that outcome would mean.

A Democratic-controlled Congress would bring more scrutiny to the White House administration. That could block Trump's judicial appointments and legislation.

There is a twist, though. Constraints on data centers from Democrats, the strategists wrote, could make the AI-investment boom more durable by reducing the likelihood of overinvestment.

Is the AI trade itself a risk?

The fourth shock involves surprises inside the AI trade. The capital-expenditure boom faces political, physical and financial constraints, according to Yardeni Research. Any proliferation of those constraints could fuel another risk-off period.

Even here, the strategists found a silver lining. Such a shock might also subdue worries about overfunding, helping the trade overall.

How is the market positioned right now?

The S&P 500 has declined five of the last seven weeks. S&P 500 futures pointed slightly higher on Monday.

The backdrop explains the note's timing. A market that has drifted lower for most of two months, combined with the strategists' view that earnings and growth remain intact, frames every shock on their list as a potential discount rather than a threat. Investors with cash to spare, in Yardeni's telling, should treat the next panic as a price tag.
