Dueling Numbers

Usually markets prefer newer data to older data, which is why I would have expected that, faced with the dueling numbers of Q4 GDP and ADP's January payroll numbers, the market would have given more weight to the payroll figure. Granted, there is more going on with today's Fed decision looming large, but still it seems strange that the ADP report would be summarily ignored. Can we chalk this up as another piece of evidence of irrationality currently infecting markets? Answer that question and you can make alot of money.
