Stocks opened higher following this morning's release of the December Consumer Price Index (CPI). However, this initial burst of buying power faded throughout the session as market participants mulled over the mixed report.  

Ahead of the opening bell, the Bureau of Labor Statistics said headline inflation was up 0.3% month-over-month in December and 3.4% higher year-over-year. Both figures are higher than what was seen in the November CPI and the annual increase was the largest in three months.
