The market doesn't like the tough talk

The S&P 500 hasn't had a day this bad since June. The index is at a session low and down 31 points to 2442.

Technically, the 55-day moving average just gave way. It had held in the dip in early July.

August is a time of year that volatility is surprisingly high and the Trump/Kim feud was the fire and fury the market needed.
