How do I short the world?
If my memory serves me correctly (and it may not), I recall reading a book about Jesse Livermore who was a legendary stock trader from almost 100 years ago, and he found a way to do almost exactly that. He saw a huge recession coming and shorted a wide variety of stocks. I don't know if you can short index funds, but you could probably make a ton of money doing so.
i've been watching permabears trying to short the stock market for years---such a dangerous game. many trading accounts have been destroyed trying to front run the next 2008. if you wanna try your luck, i suggest the proshares 3x short s&p500 ETF (SPXU) for maximum exposure.

the fact that everyone sees a global recession coming right now tells me it's not happening yet. especially after that v-shaped recovery in stocks. i think people are jumping the gun by a couple years.
