The moves come despite strong gains across US markets in recent months, reflecting growing concern over whether the rally can continue as stock valuations approach some of the highest levels recorded in market history.
Hedge Funds Cut Technology Exposure at Record Pace
According to data from Goldman Sachs, hedge funds have been net sellers of US technology stocks during six of the past eight weeks.
The cumulative market value of their technology positions has fallen by approximately 10%, marking the largest reduction in exposure to the sector since the data began being tracked more than a decade ago.
The shift suggests that professional investors are becoming increasingly cautious toward a sector that has driven a significant portion of Wall Street’s recent gains, particularly amid enthusiasm surrounding artificial intelligence.
Short Bets Against US Stocks Reach Record Levels
At the same time, short positions against stocks in the S&P 500 have climbed to historic levels.
Short interest has approached 3.8% of total shares available for trading, the highest level recorded in data from S3 Partners dating back to 2010.
Rising short interest indicates that more investors are either betting that stock prices will decline or using bearish positions as protection against a potential market correction.
S&P 500 Has Rallied Around 18% Since Late March
The growing caution comes despite a powerful rally in US equities.
The S&P 500 has gained approximately 18% since late March, demonstrating continued investor appetite for stocks.
However, the simultaneous rise in short positions highlights a widening divide over whether the market can maintain its upward momentum.
While some investors continue to expect further gains, others are reducing risk and positioning themselves for the possibility of falling stock prices.
Historically High US Stock Valuations Raise Concerns
Investor concerns extend beyond hedge fund positioning.
US equity valuations have climbed to levels that rank among the most elevated in market history, according to long-term valuation measures.
Current valuations have even surpassed levels recorded shortly before the historic Wall Street crash of 1929.
Since 1881, the US market has experienced only one major period when valuations were higher than they are today, during the dot-com bubble of the late 1990s and early 2000.
CAPE Ratio Reaches 41.4
One of the key valuation indicators attracting attention is the Cyclically Adjusted Price-to-Earnings ratio, or CAPE, developed by Nobel Prize-winning economist Robert Shiller.
The CAPE ratio compares stock prices with the inflation-adjusted average earnings of companies over the previous 10 years and is widely used to evaluate long-term market valuations.
Its historical average stands at approximately 17.8.
However, three major valuation peaks stand out:
- 32.6 in September 1929.
- 44.2 in December 1999.
- 41.4 in July 2026.
The current reading therefore places US stock valuations close to the extreme levels reached during the dot-com bubble and above those recorded ahead of the 1929 crash.
Is History About to Repeat Itself?
Historically high valuations do not necessarily mean that another market crash is imminent.
Economic conditions, monetary policy, corporate profitability and financial markets are significantly different today from previous periods.
However, elevated valuations can make markets more vulnerable to negative surprises involving corporate earnings, interest rates, inflation, economic growth or geopolitical developments.
Investors are also closely watching whether technology and artificial intelligence companies can generate sufficient earnings to justify the enormous investments and elevated valuations associated with the sector.
Technology Stocks Face a Critical Test
Technology has been one of the primary engines behind Wall Street’s gains in recent years, but the latest hedge fund positioning indicates growing caution toward the sector.
With bearish bets against US stocks reaching record levels and equity valuations approaching historic extremes, Wall Street may be entering a critical phase in which corporate earnings and economic data determine whether the rally can continue or whether a broader market correction lies ahead.
