The single currency tumbled after yesterday's brief but strong rebound to 1.3095 on short-covering, suggesting the corrective upmove from last week's 14-month low of 1.2510 has formed a temporary top there and consolidation with downside bias would be seen, however, pivotal support at 1.2609 should contain downside and yield another strong rebound later.    On the upside, above 1.2803/17 resistance area would confirm an intra-day low is made and bring a rebound to 1.2890/00 and possily 1.2950, however, said resistance at 1.3095 is expected to remain intact.
