Bank of America flashed a sell signal at 9.2 because AI stocks now make up 39% of the S&P 500 in its latest Flow Show report.

The bank's "bull-bear" indicator flashed a sell signal at 9.2, marking the deepest sell-off zone since May 2026.
This indicator has historically been 60% accurate, and global equities typically retreat 2–3% within 2–3 months after such signals, with maximum declines reaching 15–20%.
Meanwhile, stocks related to AI now account for 39% of the S&P 500, reaching a concentration level similar to the historic extremes of late 19th-century railroad stock speculation.
The U.S. Treasury yield curve has shown a bearish "flattening" since Fed nominee Kevin Warsh was announced on January 30.
The 2–10 year spread has narrowed from 75 basis points to 25 basis points.
However, contrary to this warning, the U.S. stock market attracted a record weekly net inflow of $119.2 billion, with annualized data potentially reaching a historic high of $739 billion. #美伊谈判第一轮结束
