* Equities have recently trended to the upside, buoyed by strong economic data and the U.S. Federal Reserve's commitment to be "patient" about raising interest rates.

A measure of consumer confidence, which will be released at 10 a.m. (1500 GMT), is seen rising to 93 in December, from the previous reading of 88.7.
