UBS’s Baweja warns of margin pressure risk for stocks in 2027

Enjoy the rally while it lasts. That’s essentially the message from Bhanu Baweja, chief strategist at UBS Investment Bank, who sees strong US earnings growth pushing stocks higher in the near term before the picture gets considerably murkier heading into 2027.

Baweja’s thesis is straightforward: corporate margins, the engine behind much of the post-pandemic equity surge, face mounting pressure as the calendar flips to next year. The result could be a stalling in returns that catches complacent investors off guard.

The case for near-term optimism, and the cliff after it

Back in January 2026, he described the year ahead as one that would deliver “decent returns but more mediocre returns” compared to what investors had grown accustomed to. Not a crash call. Not a moonshot prediction. Just a realistic assessment that the easy money phase of the cycle was winding down.

By April, his tone had shifted further toward caution. He explicitly encouraged investors to “play defense” in equity markets, citing geopolitical uncertainties as a primary concern.

The most recent layer of his analysis zeroes in on margins. Strong nominal growth has been the dominant force propping up markets, but Baweja draws a careful distinction: it’s real economic activity doing the heavy lifting, not inflation. His timeline puts the inflection point squarely in 2027, when he expects returns to flatline.

Consumer spending: the canary in the coal mine

As of May 2026, he flagged a potential slowdown in US consumer spending as the single biggest threat to the stock market rally.

Consumer spending accounts for roughly two-thirds of US GDP. When wallets tighten, the ripple effects move through corporate revenue lines faster than most models predict.

What defensive positioning actually looks like

Baweja’s framework, laid out in a UBS podcast from November 2025 discussing the global economics and market outlook for 2026-2027, emphasized a shift away from high-beta, momentum-driven trades toward more resilient parts of the market.

Baweja’s credibility on these calls carries weight. He leads strategy at UBS Investment Bank, which has achieved top rankings in Institutional Investor surveys and former Extel polls.

The bigger picture for risk assets

For investors across all markets, the sequencing matters enormously. The next several months could still deliver positive returns as earnings momentum carries forward. Baweja is essentially arguing that the window for taking profits and repositioning is now, not after the margin compression has already shown up in quarterly reports.

Baweja has consistently identified geopolitical risk as a wildcard that could accelerate the timeline for defensive positioning.
