Sell SPY by Feb 28, 2027.

Some of the most common reasons pundits believe that U.S large-cap stocks are doing so poorly in 2026 are: a. Fear of an overvaluation in AI-related stocks. b. Overvaluation of U.S. large-cap in general from 2025. c. Fear of an economic slowdown. d. U.S tariffs 7 trade policies. e. Geopolitical uncertainty. I believe a and b are largely responsibility, but does anyone have any other reasons, e.g. earnings slow down, weak forward guidance by many companies?
