The US dollar retreated after PMI data showed a slowdown in business activity. However, the euro’s fall below parity and July’s low indicates that sellers are in control. As last month’s rally turned out to be a dead cat bounce, the path of least resistance would be down. After the RSI sank into oversold territory, 0.9900 from December 2002 saw some bargain hunting. Though the former demand zone around 1.0040 could be a tough level to crack. Renewed selling would send the single currency towards 0.9700.
