The low-volume “dog days of summer” have been anything but uneventful. Rather than a sleeping dog, this summer has been more like a rabid dog—gyrating wildly and scaring the heck out of everyone in its path.

Kids are returning to school in some parts of the country already, and many portfolio managers and traders will begin returning to their desks. But what they are finding in the market this week is quite different than they would have seen last week.
