Why you Must NEVER EVER EVER short this market.

The Federal Reserve Stock Balance sheet is 3.691 Trillion or an estimated 14% of market cap : federalreserve.gov/monetarypolicy/bst_recenttrends.htm
The private institutional holdings of the market is 80% : pionline.com/article/20170425/INTERACTIVE/170429926/80-of-equity-market-cap-held-by-institutions

Both parties have the ability to utilize and access unlimited cash in a fractional reserve system. The federal reserve is holding 14% of the value of the stock market since the 2008 crises - bought with digitally created / inflated money; Duetsche Bank with only a market cap of $25 Billion is able to hold $45 TRILLION in notional paper derivative contracts showing how leveraged the system is. It's a leverage of 1800:1!

Once you understand that artificial GDP will be supported at all costs, even at the possible destruction of the dollar, you realize that shorting is futile, there is only BTFD.
