【Fear of Missing Out and Bubble Panic Intertwined, Indicating Increased Stock Market Volatility in 2026】

The U.S. stock market may continue to exhibit high volatility in 2026: investors are worried about missing out on the upward opportunities brought by AI, while also fearing that this is a bubble that will eventually burst. Over the past 18 months, a significant sell-off followed by rapid rebounds has become the norm, and this trend is likely to continue next year.

On one hand, AI is still in the stage of commercialization, and the related industrial chain continues to attract capital, which may trigger a phase of sharp increases; on the other hand, if performance cannot keep up with valuation expansion, or if there are changes in liquidity and policy environment, the market may experience a severe pullback. Some strategists believe that the AI sector may replay the cycle of technological revolution "prosperity—collapse."

Therefore, a more critical feature of 2026 is differentiation and fluctuations. Investors need to control their positions, focus on targets with stronger profit certainty, and respond to volatility through batch trading and dynamic rebalancing. Long-term opportunities still exist, but short-term market trends will be more influenced by emotions and liquidity.
