Nigel Green, Chief Executive Officer of global financial advisory giant deVere Group, says global investors are entering a moment of truth as a cascade of heavyweight US events converge — a GDP snapshot, a central bank verdict, a key jobs update, and earnings from the titans of tech — all within three days that could reset expectations for the remainder of the year.

deVere Group, one of the world’s largest independent advisors of specialist global financial solutions to international, local mass affluent, and high-net-worth clients, has a network of offices around the world servicing over 80,000 clients who together control $14bn under advisement.

According to Green, “this is no ordinary week, it’s the pulse-check that could either reignite confidence or shatter the summer surge.

“We’ve seen equity indices pushing into rarefied territory, but the market’s next move hinges on how these signals stack up.”

Recent resilience in US stocks, he believes, has been built on a mix of steady consumer data, optimism over artificial intelligence, and the assumption that inflation is softening. But that narrative will now face a barrage of reality checks.

Growth data lands on Wednesday, followed by a crucial Federal Reserve policy update and a deluge of corporate results — including Microsoft, Meta, Apple, and Amazon, whose combined valuations tower above $11 trillion.

“Any one of these would be enough to stir volatility. Together, they’re a reckoning,” Nigel Green adds. “Investors need to be braced for sharp pivots.”

The stakes are rising in part because of investor unease over valuations. The S&P 500 is trading well above its long-term earnings multiple, with AI-fueled enthusiasm carrying big tech higher.

Yet beneath the surface, there’s apprehension: will the real economy justify the price tags?

“This week may deliver answers — or more questions. But either way, it’s going to shake out the complacency,” says Green.

Thursday will be dominated by the Fed’s decision, with rates expected to hold steady for now. But the real drama is what follows: will Chair Jerome Powell signal a shift toward cutting later this year, or suggest patience as tariff-related inflationary effects play out?

“There’s a growing split within the Fed, and the bond market knows it,” says the deVere CEO.

“The divergence between those urging immediate relief and others advocating restraint is widening. That debate will define credit markets in the months ahead.”

Complicating matters further is President Trump’s looming tariff deadline, set for the early hours of Friday.

Washington has already clinched new trade arrangements with the UK, Japan, and parts of Europe, but talks with others remain unresolved. The clock is ticking, and investors are watching whether Trump enforces ‘reciprocal’ levies on those without a deal, or grants another stay.

“Tariff politics and monetary policy are now tightly interwoven,” Nigel Green warns. “If new duties kick in, it will alter inflation assumptions, squeeze margins, and challenge the Fed’s path.”

Friday’s US jobs report will round off the trifecta, with economists forecasting a slowdown in hiring. Any surprise — positive or negative — could rattle rates, equities, and currency markets in equal measure. And as month-end approaches, funds are already repositioning, raising the chance of outsized moves.

“The volatility cocktail is potent: tech earnings, economic data, policy direction, trade tension, and portfolio flows — all hitting at once,” says the chief executive.

“This is a crucible moment. The tone set this week will echo through the autumn.”

Despite the turbulence, Nigel Green remains constructive longer term, particularly on firms embracing technological transformation and sectors insulated from policy risk. But he cautions against complacency.

“Markets are at a fork, and the decisions made over these three days are likely to redraw the map,” he concludes.
