[Fear of Missing Out and Bubble Panic Intertwined, Indicating Increased Fluctuation in the Stock Market by 2026]

The US stock market may continue to experience high Fluctuation patterns in 2026: investors are both worried about missing out on the upward opportunities brought by AI and concerned that this is a bubble that will eventually burst. Over the past 18 months, the alternating pattern of significant sell-offs and 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 funding, 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 field may repeat the cycle of technological revolution "prosperity—collapse."

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