Here's a second round from our Technical Tuesday expert, Chris Kimble. Chris explains:

For many market technicians, copper is a superb leading indicator owing to its varied uses in manufacturing and housing/construction. Trucking reflects the movement of goods — also a good economic indicator.

Both peaked and rolled over together in early 2008, anticipating the depth of the forthcoming economic slowdown. Copper hit its low in late 2008, over three months before the S&P 500 low, and then took off like a rocket.

Many debate whether the economy is really getting better. I would suggest the next move in copper and trucking will tell us a ton. Both have been in a sideways pattern, back at the top of the trading range. Should an upside breakout take place, this would be a sweet indication that things are improving on Main Street as well as Wall Street!
