US Housing Starts and Building Permits - higher leads to rally after some time

The Housing Starts and Building Permits data from the USA was released today December 20th 2012
at 8:30am EST, 13:30 GMT. It was higher and although the initial reaction was small it did lead to a rally in all risky assets...AUDUSD, CADJPY, DAX, EMini S&P 500 futures

The market is very thin, no volume due to the approaching Christmas holidays so the reaction might have been a bit exaggerated. However the number was alot higher than the median estimate, and hte largest deviation for awhile.

Here the figures:

US Housing Starts m/m

Actual: 685k Prior: 628k Revised: 627k
