Is the Euro About to Rally to 120?

The currency markets are signalling that a massive shift might be about to happen.
According to a Bank of America/ Merrill Lynch fund manager survey, the US Dollar ($USD) is the single most crowded trade on the planet.
In a fiat world, the value of a given currency is based on where it trades relative to other currencies. In the case of the $USD, the Euro comprises 56% of the basket of currencies against which the $USD is valued.
Put another way, whatever happens to the Euro will effectively trigger an inverse reaction in the $USD.
