It’s too complicated to try to figure out which stocks to short and when. Rather, the play is to invest in solid companies that produce non-bubble goods and services and will still be producing that after AI economy crashes. UPS, Kraft-Heinz, Edison International, etc. These companies pay out 5%+ dividend yield and sell massive amounts of real world services and goods that will still be necessary to households and businesses no matter how badly the AI economy craters.
