Stocks opened higher across the board Wednesday as investors cheered the latest inflation data. The main indexes struggled as the session wore on, though, as anxiety grows ahead of tomorrow morning's release of the September Consumer Price Index (CPI) report and the start of third-quarter earnings season.  

This morning's data from the Bureau of Labor Statistics showed the September producer price index (PPI), which measures what businesses are charging suppliers for goods, rose 0.5% month-over-month, slower than August's 0.7% increase but above economists' estimates, as gas prices remained high. On a year-over-year basis, the PPI was up 2.2% – its biggest annual increase since April.
