Stock markets opened higher on Tuesday as oil prices dipped, helping investors recover slightly after Monday's losing session. International crude prices fell 3%, with Brent down to $78.50 a barrel. US oil prices were also down 3% to $74.77 a barrel.

Oil prices continued rising on Monday as concerns mount that escalating conflict in the Middle East could disrupt global oil supply.

Finally, the September CPI report is also due out this Thursday. Economists expect the CPI index to rise 2.3% year-over-year in September, down from 2.5% in August. Bank of America analysts note that an upside surprise in last month's inflation reading has the potential to send stocks on a roller coaster this week.
