The Dow had a rough day today, falling more than 100 points (0.8%) as investors were reminded that the European debt crisis remains far from solved. Spain put off making a decision on seeking a bailout, and German unemployment fell for the fifth consecutive month. In the U.S., consumer spending increased less than economists had predicted. All this added up to a triple-digit loss for the Dow.

Looking at individual stocks, Caterpillar was the Dow's biggest loser, dropping 1.9%. Competitor Joy Global recently cut its full year profit and sales forecasts on slowing commodity demand in China and the U.S. Still, this is  a stock well positioned for emerging market growth, and trading at a very attractive 10 times earnings. Outside the Dow, First Solar plunged 18% today after a report said it would cut deliveries to a $1.8 billion power plant that it's building in Arizona.
