Corporate earnings are expanding at a pace that significantly outstrips the broader economy, a divergence that has fueled persistent bubble concerns among investors. The case for caution rests on the premise that such outsized growth is unsustainable, yet the risk is that current valuations may already be pricing in a normalization that has not yet arrived. What complicates this narrative is the specific trajectory laid out by major institutional strategists, who argue that while the pace will decelerate, it will not collapse.
A team at Goldman Sachs, led by strategist Ben Snider, outlined this view in a recent note. The bank projects that S&P 500 earnings per share growth will slow to 11% in 2027 and remain at that level through 2028. This figure represents a distinct deceleration from recent highs, acknowledging that the exceptional growth rates of the past few years are unlikely to persist indefinitely. However, the projection does not suggest a return to single-digit growth or a contraction, which would signal a more severe economic cooling. The read-through here is that the market is being asked to reprice its expectations from a hyper-growth regime to a still-healthy, mid-teens-to-low-double-digit growth environment. This adjustment is the central tension for equity allocators, who must determine if current prices reflect this specific 11% terminal growth rate or if they are anchored to higher expectations.
The counterargument to the bubble thesis is straightforward: if earnings continue to grow at 11% annually for the next two years, the fundamental support for current valuations remains intact. Skeptics of the bubble narrative point to the resilience of corporate profitability, suggesting that the initial surge in earnings was not merely a cyclical blip but a structural shift in productivity and demand. From this perspective, the Goldman Sachs forecast validates the market's optimism rather than debunking it. The argument holds that investors are not pricing in perfection, but rather a sustainable, albeit slower, expansion that still delivers strong absolute gains. This view posits that the fear of a bubble is misplaced because the underlying business fundamentals are still expanding at a rate that justifies premium multiples.
On balance, the facts resolve the debate only partially. The Goldman Sachs team has provided a concrete anchor point: 11% growth in 2027 and 2028. This is a specific, sourced projection that allows for a clear assessment of whether current market prices are aligned with reality. The line to watch is whether actual earnings reports in the coming quarters begin to track toward this 11% figure or if they continue to surprise to the upside, which would invalidate the premise of a significant slowdown. Until the data confirms the deceleration, the tension between the bubble narrative and the resilience thesis remains unresolved. The market will continue to oscillate between these two views, with the 11% projection serving as the benchmark against which all future earnings surprises are measured.
