Goldman Sachs warns the US stock bull market may see its final leg up, with net equity supply in 2027 set to hit the highest since 2000
BlockBeats news, November 9, Tony Pasquariello, Goldman Sachs' global head of hedge fund coverage, warned that the three major drivers supporting the US stock market's rise over the past 4 years—earnings growth, fund flows and the AI narrative—are all showing marginal deterioration. Although the S&P 500 is still expected to complete a final leg up by year-end, the market in 2027 may face the largest net equity supply shock since the bursting of the dot-com bubble in 2000, and index volatility may also trend higher.
Pasquariello pointed out that S&P 500 earnings growth reached 33% in the second quarter and an estimated 35% in the third quarter, but growth momentum may be peaking. Goldman Sachs expects S&P 500 earnings per share (EPS) to still grow about 18% in 2027, but changes in AI capital expenditure may bring significant downside risk.
The funding side is also under pressure. Goldman Sachs prime brokerage data show that over the past 20 trading days, hedge funds sold global AI stocks at the fastest pace in more than 5 years, deviating from the historical average by more than 3 standard deviations. Weaker corporate buybacks, shrinking purchases by overseas investors and CTA strategies following the sell-off further weaken the market's capacity to absorb supply.
Goldman Sachs expects that IPOs by large companies such as SpaceX and Anthropic, as well as tech giants using more cash flow for AI infrastructure construction rather than stock buybacks, will jointly push net equity supply in the US stock market in 2027 to the highest level since 2000.
The AI narrative is also beginning to diverge. The market expects the pace of capital expenditure growth by tech giants to slow from 96% this year to 44% next year, and net free cash flow consumption by hyperscale cloud providers reached 31000000000 USD in the third quarter. Goldman Sachs believes the market is shifting from previously mainly pricing the growth space brought by AI investment to also assessing the uncertainty of capital expenditure sustainability and investment returns.
On valuation, the Nasdaq 100's forward price-to-earnings ratio has fallen to 18.4 times, the lowest level since 2020. However, Pasquariello cited the views of two veteran investors saying that the current stock market still looks overly optimistic compared with the credit market, and that pressure on AI-related high-yield bonds may mean the credit market is the first to reflect financing risk.
Another Goldman Sachs strategist, Rich Privorotsky, believes this round of adjustment is closer to the liquidity event of 1998 rather than the dot-com bubble burst of 2000, but also acknowledged that the current scale of AI investment and uncertainty of returns have unsettling similarities with 2000.
