In a Tokyo-less Asian session, the dollar had begun the week bid, but quickly reversed in early Europe, which saw the euro rise more than a cent off the $1.2666 low. It was largely a short-covering bounce, but as North American players take their posts, it is running out of steam, unable to take out the $1.28 level , which would and trigger another round of short covering. Sentiment toward the single currency is still overwhelmingly bearish, but there seems to be a growing sense that it may have come too far too fast.
Given the extended positioning and sentiment, the market is vulnerable to a larger correction. Support for the euro is seen in the $1.2720-40, provided this area holds, short-term momentum traders may begin trimming positions. The euro has not taken out the previous day's high since Jan 3 (and that might say more about the fact that markets were largely closed on Jan 2). Friday's high was near $1.2813.
