The strongest and weakest currencies for Feb 5th

The strongest and weakest currencies for Feb 5th

The EU revised growth to the upside. Short covering. Technical buying. Hope that Greece will stay in the EU and a solution will be found. Perhaps expectations the US Employment will be weaker tomorrow and the Fed will put off easing. All can be reasons for the rise today. Are any of them strong reasons to buy? Not really but for today, the EUR was the strongest currency of the day

The weakest currency is the JPY today. The currency was up most against all currencies other than the USD. The EURJPY, GBPJPY, CADJPY all benefited from overall buying in the the EUR, GBP and CAD pairs in general. That helped all the JPY crosses move higher (weaken the JPY in the process).
