I don’t think Zitron is recommending anyone short anything. That’s carries a ton of risk.
What you consider “losing money” I might consider “choosing not to participate in an ongoing global financial scam at the cost of my retirement growing slightly slower for a while”.
A bubble prophet that doesn't have any short positions?
Why doesn't he put money where his mouth is?
If you choose to believe that, then you pretty well can’t have your money anywhere near the market at any time ever.
