# Five Leading Indicators of "Shorting the U.S. Stock Bubble" in the Eyes of Wall Street

Bank of America chief strategist Hartnett has listed "five important signals" as leading indicators for investors to start shorting:

-   The Bank of America stock ETF BKX rises above $140;
-   The bond spread of technology companies exceeds 100bp;
-   The U.S. junk bond ETF JNK falls below $80;
-   Bitcoin falls below $100,000;
-   Increased unemployment in the U.S. leads to the younger generation of Americans having no money to continue buying high-risk assets (he believes stocks and digital currencies are their only source of livelihood).

From the above indicators, Hartnett believes that rising interest rates (especially for junk bonds and tech bonds) will hinder the "infinite bullets" of AI infrastructure, and the sustainability of retail investors (Bitcoin and unemployment are barometers) is crucial for whether U.S. stocks can continue to rise.
