White line is the most important support from 2009, the brexit is a black swan, and it's influence can't be digest in 2 trading day. SPX has see-war above 2000 about 2years, all things indicate that the market will go down.
When the smart money leave from the stock market, the safe haven will be popular. The stock and the safe-haven are inverse, we can see the money-flow through this chart, just like 2008. I believe that the smart money always goes ahead.
