Near all-time highs and a ~16% rally from the March pullback, the S&P 500 has staged a historic rally driven by an earnings supercycle and pricing in an artificial intelligence (AI) revolution. For investors who’ve enjoyed the returns, it’s natural to wonder: How much better can stock market returns get from here, especially with a bond market in tumult?
While not the base case, the S&P 500 could reach as high as 9,000 by mid-2027. A ~22% gain from current levels may seem optimistic, but remains entirely plausible. Here’s how.
A bigger, broader AI supercycle
The AI revolution is already driving earnings growth—and by extension the stock market—at a record clip. There hasn’t been a streak of six consecutive quarters of double-digit earnings growth since the aftermath of the global financial crisis (GFC).
Global earnings growth is booming, accelerating from 15.3% year-over-year in the fourth quarter to 22.6% in the first quarter of this year. That’s the highest in over four years. This is already an impressive showing, but even more extraordinary given it’s not a rebound from a cyclical downturn, like after the GFC, but rather an acceleration from an already high base.
For now, it’s being driven by the tech sector. That’s both a concentration risk and an opportunity. The path to 9,000 extends beyond the tech sector. It relies on broader AI adoption across sectors that increases productivity and bolsters margins across the board.
It’s no secret that the macro narrative in the United States centers on AI. But the market is now transitioning its focus from infrastructure to adoption. While the hardware layer continues to print extraordinary profits, the secular earnings story is moving downstream.
The largest cloud giants are deploying over $800 billion in AI capital spending annually, scaling to an estimated $1.16 trillion by 2027. This acts as a massive fiscal stimulus for the private sector, flowing directly into semiconductors, specialized hardware, advanced cooling, power grids and commercial construction, among other adjacent areas.
For companies to sustain mid-teens earnings growth without igniting inflation, productivity needs to accelerate. We’ve seen it before. Productivity boomed in the late 1990s, annualizing ~2.8%. Meanwhile, the index delivered five consecutive years of over 20% returns between 1995 and 2000. It can happen again.
Digesting a bond market sell-off
What gets in the way? The narrative feels unstoppable, but in any bull case, it’s prudent to entertain the risks—especially ones that come from other asset classes. While the Federal Reserve is most likely to take a wait-and-see approach to energy-led increases in headline inflation, the bond market isn’t always as patient.
U.S. 10-year yields rose by over 40 basis points over the last four weeks. Across the Atlantic, U.K. gilt yields, German bunds and Japanese government bonds (JGBs) experienced similar moves around the same timeframes driven by a repricing of central bank policy expectations.
Naturally, it has spooked equity markets. Investors are asking one key question: Can a stock market near all-time highs digest a level of rates that in some parts of the yield curve was last seen in 2007?
It’s not about the level of rates itself, but rather the magnitude of the move that matters more. An over 40 basis point move in 10-year Treasury yields isn’t uncommon. Similar moves of this margin have happened six times in the last five years, notably in the wake of Liberation Day and after the 2024 U.S. presidential election. But this broad-based sell-off in rates hasn’t happened in over a year. Perhaps that’s why the move feels so acute this time around in equities.
