When we left town on Friday trading was as slow as the traffic on the interstate. Labor Day is the last holiday of the summer. No one wants to miss it. The Dow fell 30 points on Friday. Gold dropped $16 an ounce. An ounce of the yellow metal sells for $1,390 at writing. But that was the summer. And the summer is history. Now we’re in the “R” months: September, October, November and December.
