Stocks are poised for a significant movement in the coming year, as predictions from a leading research firm suggest an impending rally followed by a steep correction. Capital Economics has shared insights that forecast the S&P 500 could reach as high as 8,000 by 2026 before experiencing a drop to around 7,000 in the following year, marking a decline of approximately 13%. This anticipated correction reflects what analysts describe as a return to a “more normal level” for the index.
Jennifer McKeown and William Jackson, economists at the firm, highlighted the possibility of a market “collapse under its own weight,” suggesting that while investors continue to believe in the long-term advantages of artificial intelligence (AI) for the economy, they may soon reassess the stretched valuations of major tech firms. They warned that, in a worst-case scenario, the market could see a pullback as severe as 30%.
Several factors contribute to this potential downturn:
-
Oversized Valuations
Although corporate earnings remain robust, Thomas Mathews, head of markets at Capital Economics, noted that tech stock valuations appear high and could be on the rise. He referenced the price-to-forward 12-month earnings ratio for the U.S. tech sector, which reached its highest point since the dot-com bubble last year before showing signs of easing. Mathews cautioned that while current valuations are not excessively high, the enthusiasm surrounding AI technology could push them to unsustainable levels in the long run. -
Potential Slowdown in Tech Earnings
Earnings growth in the S&P 500 has largely been concentrated within the tech sector, creating a vulnerability. Mathews suggested that while rapid earnings growth might continue for now, there is a risk that expectations for tech company earnings could inflate to a “bubble,” leading to a sharp drop when reality sets in. -
Economic Slowdown Risks
The longevity of the AI rally may also hinge on the performance of the U.S. economy. Matthews acknowledged that while current economic growth seems strong and the risk of recession is minimal, any significant economic slowdown could jeopardize investor confidence in AI-related stocks. -
AI Demand and Global Competition
There are concerns that demand for AI might not meet initial expectations or that rival innovations from countries like China could challenge U.S. tech firms. Mathews pointed to the impact of AI capital expenditures, which have caused significant market fluctuations in the past year. The emergence of Chinese competitors, equipped with innovations such as DeepSeek, underscores the competitive threats facing American technology companies. -
Geopolitical Risks
Recent geopolitical tensions have already created volatility in the markets, illustrating their potential impact on the AI sector. Capital Economics noted that approximately 40% of revenue for U.S. tech companies comes from European allies and partners. The firm indicated that notable geopolitical conflicts could influence the AI sector significantly, particularly if they affect the U.S. economy or impact tech companies’ earnings through other avenues.
In conclusion, while the stock market may experience an upward trajectory in the short term, signals from Capital Economics point to an impending reassessment of valuations coupled with external economic pressures and geopolitical uncertainties that could create turbulence in the years ahead.
