Growing AI bubble concerns push short bets on US stocks to highest since 2010
Odaily Odaily reported that as concerns over AI-related risks intensify, bearish bets against the U.S. stock market are climbing to historic highs, reflecting market skepticism about the sustainability of the current rally.
Data shows that short interest in S&P 500 index constituents as a percentage of free-float shares has approached approximately 3.79%, the highest level since S3 Partners began tracking the data in 2010. Meanwhile, the short ratio for Russell 3000 index components recently rose to 6.3%, also a new record.
Previously, since late March, the S&P 500 has accumulated a gain of about 18%, driving the market higher. However, some investors are beginning to worry about the sustainability of the AI-driven tech rally and whether the market faces correction risks amid high valuations.
Analysts point out that the significant increase in short positions reflects investor concerns over AI bubble risks, earnings expectations, and market concentration. It could also be an important signal of increasing market volatility.
However, historical data suggests that high levels of short interest do not necessarily mean an imminent market decline. If corporate earnings continue to improve or AI investments yield better-than-expected returns, short covering could, in turn, fuel further stock market gains. (Bloomberg)
