Peter Schiff - Dollar Bulls Beware
By late 2009, as the U.S. dollar flirted with multi-year lows against most foreign currencies, big investment players crowded into trades that shorted the greenback. Commentators noted that the anti-dollar momentum had taken on a life of its own and that the trade had become too crowded. It is true that markets have a nasty tendency to move against the crowd. When a lot of traders agree on a particular trade, it's more likely that in the short-run the opposite trade will be a winner.
The 2008 "flight to safety" rally of the U.S. dollar was a once in a lifetime event that presented huge opportunities for aggressive currency traders. By December 2008, after rallying 25% over the previous five months, the dollar topped out. However, there were many speculators who had come somewhat late to the party, as well as many others who had ridden the dollar up and were thus sitting on huge unrealized gains.
Those technical reasons, combined with the re-emergence of strong growth in emerging markets and solid earnings from overseas companies, redirected investment flows away from the dollar. 2009 became a year of dollar weakness, with the buck giving back nearly all of its gains. At that point, most people made the reasonable conclusion that the decline would continue.
