How the weak dollar helps Europe, and Ralph Lauren

Since January 2001, the dollar has lost much of its value. It's fallen 71% in value from the 92 cents to the Euro at which it traded back then. This is great news for Europeans who have a chance to come to the U.S.

I am teaching a group of students from Italy this month. Their friends advised them to come to the U.S. with empty suitcases so they could fill them up with clothing and other retail goods. That's because when they come here, the clothing that they buy in Europe looks to be on a 50% off sale. This leads to what may be an investment opportunity for Americans -- Polo Ralph Lauren (NYSE: RL). (Its stock is not overpriced; it's lost 39% of its value in the last year and it trades at a price earnings-to-growth (PEG) ratio of 1.2 -- a P/E of 15.7 and earnings forecast to grow 12.8% to $4.51 in 2009.)

How so? The Italian students are eager to gobble up as much of its merchandise as they can. If these students are a microcosm of Europeans, we can expect them to flock to the East Coast of the U.S. during their summer break to boost their wardrobes. They also like Lacoste and Gucci as well -- both of whose products are selling at screaming discounts here for those who get paid in Euros.
