Optimism about Greece seems to have pushed the Euro upwards against the US Dollar. The current trend is upwards. It is now due a downswing. Will the upward trend be sustained? I doubt it. The Dollar zone is promising an imminent rise in interest rate, maybe as soon as September, while the Euro zone is only beginning its ZIRP and QE. The pressure has to be for the Dollar to rise in the months ahead, even as the DOW and NASDAQ falter.
